Volume 5 — THE MECHANISM OF DETUMESCENCE. (continued 2)

"The first fact that I hit upon was the importance of pressure. As one of my informants picturesquely phrases it—'the tighter the fit the greater the pleasure.' This agrees, too, with their unanimous testimony that the pleasurable sensations were much greater when the orgasm occurred simultaneously in the man and woman. Their analysis seldom went further than this, but a few remarked that the distinctive sensations accompanying the orgasm seem to begin near the root of the penis or in the testes, and that they are qualitatively different from the tickling sensations which precede them.

"These tickling sensations are caused, I think, by the friction of the glands against the vaginal walls, and are supplemented by other sensations from the urethra, whose nerves are stimulated by pressure of the vaginal walls and sphincter. The specific sensation of the orgasm begins, I believe, with a strong contraction of the muscles of the urethral walls along the entire length of the canal, and is felt as a peculiar ache starting from the base of the penis and quickly becoming diffused through the whole organ. This sensation reaches its climax with the expulsion of the semen into the urethra and the consequent feeling of distention, which is instantly followed by the rhythmic peristaltic contractions of the urethral muscles which mark the climax of the orgasm.

"The most careful introspection possible under the circumstances seems to show that these sensations arise almost wholly from the urethra and in a far less degree from the corona. During periods of great sexual excitement the nerves of the urethra and corona seem to possess a peculiar sensitivity and are powerfully stimulated by the violent peristaltic contractions of the muscles in the urethral walls during ejaculation. It seems possible that the intensity and volume of sensation felt at the glans may be due in part to the greater area of sensitive surface presented in the fossa as well as to the sensitivity of the corona, and in part to the fact that during the orgasm the glans is more highly congested than at any other time, and the nerve endings thus subjected to additional pressure.

"If the foregoing statements are true, it is easy to see why the pleasure of the man is much increased when the orgasm occurs at the same time in his partner and himself, for the contractions of the vagina upon the penis would increase the stimulation of all the nerve endings in that organ for which a mechanical stimulus is adequate, and the prominence of the corpus spongiosum and corona would ensure them the greatest stimulation. It seems not improbable that the specific sensation of orgasm rises from the stimulation of the peculiar form of nerve end-bulbs which Krause found in the corpus spongiosum and in the glans.

"The characteristic massiveness of the experience is probably due largely to the great number of sensations of strain and pressure caused by the powerful reflex contraction of so many of the voluntary muscles.

"Of course, the foregoing analysis is purely tentative, and I offer it only on the chance that it may suggest some line of inquiry which may lead to results of value to the student of sexual psychology."

In man the whole process of detumescence, when it has once really begun, only occupies a few moments. It is so likewise in many animals; in the genera Bos, Ovis, etc., it is very short, almost instantaneous, and rather short also in the Equidæ (in a vigorous stallion, according to Colin, ten to twelve seconds). As Disselhorst has pointed out, this is dependent on the fact that these animals, like man, possess a vas deferens which broadens into an ampulla serving as a receptacle which holds the semen ready for instant emission when required. On the other hand, in the dog, cat, boar, and the Canidæ, Felidæ, and Suidæ generally, there is no receptacle of this kind, and coitus is slow, since a longer time is required for the peristaltic action of the vas to bring the semen to the urogenital sinus. (R. Disselhorst, Die Accessorischen Geschlechtsdrusen der Wirbelthiere, 1897, p. 212.)

In man there can be little doubt that detumescence is more rapidly accomplished in the European than in the East, in India, among the yellow races, or in Polynesia. This is probably in part due to a deliberate attempt to prolong the act in the East, and in part to a greater nervous erethism among Westerns.

In the woman the specifically sexual muscular process is less visible, more obscure, more complex, and uncertain. Before detumescence actually begins there are at intervals involuntary rhythmic contractions of the walls of the vagina, seeming to have the object of at once stimulating and harmonizing with those that are about to begin in the male organ. It would appear that these rhythmic contractions are the exaggeration of a phenomenon which is normal, just as slight contraction is normal and constant in the bladder. Jastreboff has shown, in the rabbit, that the vagina is in constant spontaneous rhythmic contraction from above downward, not peristaltic, but in segments, the intensity of the contractions increasing with age and especially with sexual development. This vaginal contraction which in women only becomes well marked just before detumescence, and is due mainly to the action of the sphincter cunni (analogous to the bulbo-cavernosus in the male), is only a part of the localized muscular process. At first there would appear to be a reflex peristaltic movement of the Fallopian tubes and uterus. Dembo observed that in animals stimulation of the upper anterior wall of the vagina caused gradual contraction of the uterus, which is erected by powerful contraction of its muscular fiber and round ligaments while at the same time it descends toward the vagina, its cavity becoming more and more diminished and mucus being forced out. In relaxing, Aristotle long ago remarked, it aspirates the seminal fluid.

Although the active participation of the sexual organs in woman, to the end of directing the semen into the womb at the moment of detumescence, is thus a very ancient belief, and harmonizes with the Greek view of the womb as an animal in the body endowed with a considerable amount of activity,^[117] precise observation in modern times has offered but little confirmation of the reality of this participation. Such observations as have been made have usually been the accidental result of sexual excitement and orgasm occurring during a gynæcological examination. As, however, such a result is liable to occur in erotic subjects, a certain number of precise observations have accumulated during the past century. So far as the evidence goes, it would seem that in women, as in mares, bitches, and other animals, the uterus becomes shorter, broader, and softer during the orgasm, at the same time descending lower into the pelvis, with its mouth open intermittently, so that, as one writer remarks, spontaneously recurring to the simile which commended itself to the Greeks, "the uterus might be likened to an animal gasping for breath."^[118] This sensitive, responsive mobility of the uterus is, indeed, not confined to the moment of detumescence, but may occur at other times under the influence of sexual emotion.

It would seem probable that in this erection, contraction, and descent of the uterus, and its simultaneous expulsion of mucus, we have the decisive moment in the completion of detumescence in woman, and it is probable that the thick mucus, unlike the earlier more limpid secretion, which women are sometimes aware of after orgasm, is emitted from the womb at this time. This is, however, not absolutely certain. Some authorities regard detumescence in women as accomplished in the pouring out of secretions, others in the rhythmic genital contractions; the sexual parts may, however, be copiously bathed in mucus for an indefinitely long period before the final stage of detumescence is achieved, and the rhythmic contractions are also taking place at a somewhat early period; in neither respect is there any obvious increase at the final moment of orgasm. In women this would seem to be more conspicuously a nervous manifestation than in men. On the subjective side it is very pronounced, with its feeling of relieved tension and agreeable repose—a moment when, as one woman expresses it, together with intense pleasure, there is, as it were, a floating up into a higher sphere, like the beginning of chloroform narcosis—but on the objective side this culminating moment is less easy to define.

Various observations and remarks made during the past two or three centuries by Bond, Valisneri, Dionis, Haller, Günther, and Bischoff, tending to show a sucking action of the uterus in both women and other female animals, have been brought together by Litzmann in R. Wagner's Handwörterbuch der Physiologie (1846, vol. iii, p. 53). Litzmann added an experience of his own: "I had an opportunity lately, while examining a young and very erethic woman, to observe how suddenly the uterus assumed a more erect position, and descended deeper in the pelvis; the lips of the womb became equal in length, the cervix rounded, softer, and more easily reached by the finger, and at the same time a high state of sexual excitement was revealed by the respiration and voice."

The general belief still remained, however, that the woman's part in conjugation is passive, and that it is entirely by the energy of the male organ and of the male sexual elements, the spermatozoa, that conjunction with the germ cell is attained. According to this theory, it was believed that the spermatozoa were, as Wilkinson expresses it, in a history of opinion on this question, "endowed with some sort of intuition or instinct; that they would turn in the direction of the os uteri, wading through the acid mucus of the vagina; travel patiently upward and around the vaginal portion of the uterus; enter the uterus and proceed onward in search of the waiting ovum." (A. D. Wilkinson, "Sterility in the Female," Transactions of the Lincoln Medical Society, Nebraska, 1896.)

About the year 1859 Fichstedt seems to have done something to overthrow this theory by declaring his belief that the uterus was not, as commonly supposed, a passive organ in coitus, but was capable of sucking in the semen during the brief period of detumescence. Various authorities then began to bring forward arguments and observations in the same sense. Wernich, especially, directed attention to this point in 1872 in a paper on the erectile properties of the lower segment of the uterus ("Die Erectionsfahigkeit des untern Uterus-Abschnitts," Beiträge zur Geburtshülfe und Gynäkologie, vol. i, p. 296). He made precise observations and came to the conclusion that owing to erectile properties in the neck of the uterus, this part of the womb elongates during congress and reaches down into the pelvis with an aspiratory movement, as if to meet the glans of the male. A little later, in a case of partial prolapse, Beck, in ignorance of Wernich's theory, was enabled to make a very precise observation of the action of the uterus during excitement. In this case the woman was sexually very excitable even under ordinary examination, and Beck carefully noted the phenomena that took place during the orgasm. "The os and cervix uteri," he states, "had been about as firm as usual, moderately hard and, generally speaking, in a natural and normal condition, with the external os closed to such an extent as to admit of the uterine probe with difficulty; but the instant that the height of excitement was at hand, the os opened itself to the extent of fully an inch, as nearly as my eye can judge, made five or six successive gasps as if it were drawing the external os into the cervix, each time powerfully, and, it seemed to me, with a regular rhythmical action, at the same time losing its former density and hardness and becoming quite soft to the touch. Upon the cessation of the action, as related, the os suddenly closed, the cervix again hardened itself, and the intense congestion was dissipated." (J. R. Beck, "How do the Spermatozoa Enter the Uterus?" American Journal of Obstetrics, 1874.) It would appear that in the early part of this final process of detumescence the action of the uterus is mainly one of contraction and ejaculation of any mucus that may be contained; Dr. Paul Mundé has described "the gushing, almost in jets," of this mucus which he has observed in an erotic woman under a rather long digital and specular examination. (American Journal of Obstetrics, 1893.) It is during the latter part of detumescence, it would seem, and perhaps for a short time after the orgasm is over, that the action of the uterus is mainly aspiratory.

While the active part played by the womb in detumescence can no longer be questioned, it need not too hastily be assumed that the belief in the active movements of the spermatozoa must therefore be denied. The vigorous motility of the tadpole-like organisms is obvious to anyone who has ever seen fresh semen under the microscope; and if it is correct, as Clifton Edgar states, that the spermatozoa may retain their full activity in the female organs for at least seventeen days, they have ample time to exert their energies. The fact that impregnation sometimes occurs without rupture of the hymen is not decisive evidence that there has been no penetration, as the hymen may dilate without rupturing; but there seems no reason to doubt that conception has sometimes taken place when ejaculation has occurred without penetration; this is indicated in a fairly objective manner when, as has been occasionally observed, conception has occurred in women whose vaginas were so narrow as scarcely to admit the entrance of a goose-quill; such was the condition in the case of a pregnant woman brought forward by Roubaud. The stories, repeated in various books, of women who have conceived after homosexual relations with partners who had just left their husbands' beds are not therefore inherently impossible.^[119] Janke quotes numerous cases in which there has been impregnation in virgins who have merely allowed the penis to be placed in contact with the vulva, the hymen remaining unruptured until delivery.^[120]

It must be added, however, that even if the semen is effused merely at the mouth of the vagina, without actual penetration, the spermatozoa are still not entirely without any resource save their own motility in the task of reaching the ovum. As we have seen, it is not only the uterus which takes an active part in detumescence; the vagina also is in active movement, and it seems highly probable that, at all events in some women and under some circumstances, such movement favoring aspiration toward the womb may be communicated to the external mouth of the vagina.

Riolan (Anthropographia, 1626, p. 294) referred to the constriction and dilation of the vulva under the influence of sexual excitement. It is said that in Abyssinia women can, when adopting the straddling posture of coitus, by the movements of their own vaginal muscles alone, grasp the male organ and cause ejaculation, although the man remains passive. According to Lorion the Annamites, adopting the normal posture of coitus, introduce the penis when flaccid or only half erect, the contraction of the vaginal walls completing the process; the penis is very small in this people. It is recognized by gynæcologists that the condition of vaginismus, in which there is spasmodic contraction of the vagina, making intercourse painful or impossible, is but a morbid exaggeration of the normal contraction which occurs in sexual excitement. Even in the absence of sexual excitement there is a vague affection, occurring in both married and unmarried women, and not, it would seem, necessarily hysterical, characterized by quivering or twitching of the vulva; I am told that this is popularly termed "flackering of the shape" in Yorkshire and "taittering of the lips" in Ireland. It may be added that quivering of the gluteal muscles also takes place during detumescence, and that in Indian medicine this is likewise regarded as a sign of sexual desire in women, apart from coitus.

A non-medical correspondent in Australia, W. J. Chidley, from whom I have received many communications on this subject, is strongly of opinion from his own observations that not only does the uterus take an active part in coitus, but that under natural conditions the vagina also plays an active part in the process. He was led to suspect such an action many years ago, as well by an experience of his own, as also by hearing from a young woman who met her lover after a long absence that by the excitement thus aroused a tape attached to the underclothes had been drawn into the vagina. Since then the confidences of various friends, together with observations of animals, have confirmed him in the view that the general belief that coitus must be effected by forcible entry of the male organ into a passive vagina is incorrect. He considers that under normal circumstances coitus should take place but rarely, and then only under the most favorable circumstances, perhaps exclusively in spring, and, most especially, only when the woman is ready for it. Then, when in the arms of the man she loves, the vagina, in sympathy with the active movements of the womb, becomes distended at the touch of the turgescent, but not fully erect, penis, "flashes open and draws in the male organ." "All animals," he adds, "have sexual intercourse by the male organ being drawn, not forced, into the female. I have been borne out in this by friends who have seen horses, camels, mules and other large animals in the coupling season. What is more absurd, for instance, than to say that an entire penetrates the mare? His penis is a sensitive, beautiful piece of mechanism, which brings its light head here and there till it touches the right spot, when the mare, if ready, takes it in. An entire's penis could not penetrate anything; it is a curve, a beautiful curve which would easily bend. A bull's, again, is turned down at the end and, more palpably still, would fold on itself if pressed with force. The womb and vagina of a beautiful and healthy woman constitute a living, vital, moving organ, sensitive to a look, a word, a thought, a hand on the waist."

A well-known American author thus writes in confirmation of the foregoing view: "In nature the woman wooes. When impassioned her vagina becomes erect and dilated, and so lubricated with abundant mucus to the lips that entrance is easy. This dilatation and erectile expansion of vagina withdraws the hymen so close to the walls that penetration need not tear it or cause pain. The more muscular, primitive and healthy the woman the tougher and less sensitive the hymen, and the less likely to break or bleed. I think one great function of the foreskin also is to moisten the glans, so that it can be lubricated for entrance, and then to retract, moist side out, to make entrance still easier. I think that in nature the glans penetrates within the labia, is withstood a moment, vibrating, and then all resistance is withdrawn by a sudden 'flashing open' of the gates, permitting easy entrance, and that the sudden giving up of resistance, and substitution of welcome, with its instantaneous deep entrance, causes an almost immediate male orgasm (the thrill being irresistibly exciting). Certainly this is the process as observed in horses, cattle, goats, etc., and it seems likely something analogous is natural in man."

While it is easily possible to carry to excess a view which would make the woman rather than the man the active agent in coitus (and it may be recalled that in the Cebidæ the penis, as also the clitoris, is furnished with a bone), there is probably an element of truth in the belief that the vagina shares in the active part which, there can now be little doubt, is played by the uterus in detumescence. Such a view certainly enables us to understand how it is that semen effused on the exterior sexual organs can be conveyed to the uterus.

It was indeed the failure to understand the vital activity of the semen and the feminine genital canal, co-operating together towards the junction of sperm cell and germ cell, which for so long stood in the way of the proper understanding of conception. Even the genius of Harvey, which had grappled successfully with the problem of the circulation, failed in the attempt to comprehend the problem of generation. Mainly on account of this difficulty, he was unable to see how the male element could possibly enter the uterus, although he devoted much observation and study to the question. Writing of the uterus of the doe after copulation, he says: "I began to doubt, to ask myself whether the semen of the male could by any possibility make its way by attraction or injection to the seat of conception, and repeated examination led me to the conclusion that none of the semen reached this seat." (De-Generatione Animalium, Exercise lxvii.) "The woman," he finally concluded, "after contact with the spermatic fluid in coitu, seems to receive an influence and become fecundated without the co-operation of any sensible corporeal agent, in the same way as iron touched by the magnet is endowed with its powers."

Although the specifically sexual muscular process of detumescence in women—as distinguished from the general muscular phenomena of sexual excitement which may be fairly obvious—is thus seen to be somewhat complex and obscure, in women as well as in men detumescence is a convulsion which discharges a slowly accumulated store of nervous force. In women also, as in men, the motor discharge is directed to a specific end—the intromission of the semen in the one sex, its reception in the other. In both sexes the sexual orgasm and the pleasure and satisfaction associated with it, involve, as their most essential element, the motor activity of the sexual sphere.^[121]

The active co-operation of the female organs in detumescence is probably indicated by the difficulty which is experienced in achieving conception by the artificial injection of semen. Marion Sims stated in 1866, in Clinical Notes on Uterine Surgery, that in 55 injections in six women he had only once been successful; he believed that that was the only case at that time on record. Jacobi had, however, practiced artificial fecundation in animals (in 1700) and John Hunter in man. See Gould and Pyle, Anomalies and Curiosities of Medicine, p. 43; also Janke (Die Willkürliche Hervorbringen des Geschlechts, pp. 230 et seq.) who discusses the question of artificial fecundation and brings together a mass of data.

The facial expression when tumescence is completed is marked by a high degree of energy in men and of loveliness in women. At this moment, when the culminating act of life is about to be accomplished, the individual thus reaches his supreme state of radiant beauty. The color is heightened, the eyes are larger and brighter, the facial muscles are more tense, so that in mature individuals any wrinkles disappear and youthfulness returns.

At the beginning of detumescence the features are frequently more discomposed. There is a general expression of eager receptivity to sensory impressions. The dilatation of the pupils, the expansion of the nostrils, the tendency to salivation and to movements of the tongue, all go to make up a picture which indicates an approaching gratification of sensory desires; it is significant that in some animals there is at this moment erection of the ears.^[122] There is sometimes a tendency to utter broken and meaningless words, and it is noted that sometimes women have called out on their mothers.^[123] The dilatation of the pupils produces photophobia, and in the course of detumescence the eyes are frequently closed from this cause. At the beginning of sexual excitement, Vaschide and Vurpas have observed, tonicity of the eye-muscles seems to increase; the elevators of the upper lids contract, so that the eyes look larger and their mobility and brightness are heightened; with the increase of muscular tonicity strabismus occurs, owing to the greater strength of the muscles that carry the eyes inward.^[124]

The facial expression which marks the culmination of tumescence, and the approach of detumescence is that which is generally expressive of joy. In an interesting psycho-physical study of the emotion of joy, Dearborn thus summarizes its characteristics: "The eyes are brighter and the upper eyelid elevated, as also are the brows, the skin over the glabella, the upper lip and the corners of the mouth, while the skin at the outer canthi of the eye is puckered. The nostrils are moderately dilated, the tongue slightly extended and the cheeks somewhat expanded, while in persons with largely developed pinnal muscles the ears tend somewhat to incline forwards. The whole arterial system is dilated, with consequent blushing from this effect on the dermal capillaries of the face, neck, scalp and hands, and sometimes more extensively even; from the same cause the eyes slightly bulge. The whole glandular system likewise is stimulated, causing the secretions,—gastric, salivary, lachrymal, sudoral, mammary, genital, etc.—to be increased, with the resulting rise of temperature and increase in the katobolism generally. Volubility is almost regularly increased, and is, indeed, one of the most sensitive and constant of the correlations in emotional delight.... Pleasantness is correlated in living organisms by vascular, muscular and glandular extension or expansion, both literal and figurative." (G. Dearborn, "The Emotion of Joy," Psychological Review Monograph Supplements, vol. ii, No. 5, p. 62.) All these signs of joy appear to occur at some stage of the process of sexual excitement.

In some monkeys it would seem that the muscular movement which in man has become the smile is the characteristic facial expression of sexual tumescence or courtship. Discussing the facial expression of pleasure in children, S. S. Buckman has the following remarks: "There is one point in such expression which has not received due consideration, namely, the raising of lumps of flesh each side of the nose as an indication of pleasure. Accompanying this may be seen small furrows, both in children and adults, running from the eyes somewhat obliquely towards the nose. What these characters indicate may be learned from the male mandril, whose face, particularly in the breeding season, shows colored fleshy prominences each side of the nose, with conspicuous furrows and ridges. In the male mandril these characters have been developed because, being an unmistakable sign of sexual ardor, they gave the female particular evidence of sexual feelings. Thus such characters would come to be recognized as habitually symptomatic of pleasurable feelings. Finding similar features in human beings, and particularly in children, though not developed in the same degree, we may assume that in our monkey-like ancestors facial characters similar to those of the mandril were developed, though to a less extent, and that they were symptomatic of pleasure, because connected with the period of courtship. Then they became conventionalized as pleasurable symptoms." (S. S. Buckmann, "Human Babies: What They Teach," Nature, July 5, 1900.) If this view is accepted, it may be said that the smile, having in man become a generalized sign of amiability, has no longer any special sexual significance. It is true that a faint and involuntary smile is often associated with the later stages of tumescence, but this is usually lost during detumescence, and may even give place to an expression of ferocity.

When we have realized how profound is the organic convulsion involved by the process of detumescence, and how great the general motor excitement involved, we can understand how it is that very serious effects may follow coitus. Even in animals this is sometimes the case. Young bulls and stallions have fallen in a faint after the first congress; boars may be seriously affected in a similar way; mares have been known even to fall dead.^[125] In the human species, and especially in men—probably, as Bryan Robinson remarks, because women are protected by the greater slowness with which detumescence occurs in them—not only death itself, but innumerable disorders and accidents have been known to follow immediately after coitus, these results being mainly due to the vascular and muscular excitement involved by the processes of detumescence. Fainting, vomiting, urination, defæcation have been noted as occurring in young men after a first coitus. Epilepsy has been not infrequently recorded. Lesions of various organs, even rupture of the spleen, have sometimes taken place. In men of mature age the arteries have at times been unable to resist the high blood-pressure, and cerebral hæmorrhage with paralysis has occurred. In elderly men the excitement of intercourse with strange women has sometimes caused death, and various cases are known of eminent persons who have thus died in the arms of young wives or of prostitutes.^[126]

These morbid results, are, however, very exceptional. They usually occur in persons who are abnormally sensitive, or who have imprudently transgressed the obvious rules of sexual hygiene. Detumescence is so profoundly natural a process; it is so deeply and intimately a function of the organism, that it is frequently harmless even when the bodily condition is far from absolutely sound. Its usual results, under favorable circumstances, are entirely beneficial. In men there normally supervenes, together with the relief from the prolonged tension of tumescence, with the muscular repose and falling blood-pressure,^[127] a sense of profound satisfaction, a glow of diffused well-being,^[128] perhaps an agreeable lassitude, occasionally also a sense of mental liberation from an overmastering obsession. Under reasonably happy circumstances there is no pain, or exhaustion, or sadness, or emotional revulsion. The happy lover's attitude toward his partner is not expressed by the well-known Sonnet (CXXIX) of Shakespeare:—

He feels rather with Boccaccio that the kissed mouth loses not its charm,

In women the results of detumescence are the same, except that the tendency to lassitude is not marked unless the act has been several times repeated; there is a sensation of repose and self-assurance, and often an accession of free and joyous energy. After completely satisfactory detumescence she may experience a feeling as of intoxication, lasting for several hours, an intoxication that is followed by no evil reaction.

Such, so far as our present vague and imperfect knowledge extends, are the main features in the process of detumescence. In the future, without doubt, we shall learn to know more precisely a process which has been so supremely important in the life of man and of his ancestors.

In some parts of the world this is further aided by artificial means. Thus it is stated by Riedel (as quoted by Ploss and Bartels) that in the Gorong Archipelago the bridegroom, before the first coitus, anoints the bride's pudenda with an ointment containing opium, musk, etc. I have been told of an English bride who was instructed by her mother to use a candle for the same purpose.

Onanoff (Paris Société de Biologie, May 3, 1890) proposed the name of bulbo-cavernous reflex for the smart contraction of the ischio-and bulbo-cavernosus muscles (erector penis and accelerator urinæ) produced by mechanical excitation of the glans. This reflex is clinically elicited by placing the index-finger of the left hand on the region of the bulb while the right hand rapidly rubs the dorsal surface of the glands with the edge of a piece of paper or lightly pinches the mucous membrane; a twitching of the region of the bulb is then perceived. This reflex is always present in healthy adult subjects and indicates the integrity of the physical mechanism of detumescence. It has been described by Hughes. (C. H. Hughes, "The Virile or Bulbo-cavernous Reflex," Alienist and Neurologist, January, 1898.)

A woman of 30, normal and intelligent, after conversing on love and passion, and then listening to the music of Grieg and Schumann, felt real and strong sexual excitement, increased by memories recalled by the presence of a sympathetic person. When then tested by the dynamometer the average of ten efforts with the right hand was found to be 28.2 (her normal average being 31.1) and with the left hand 28.0 (the normal being 30.0). There was, however, great variability in the individual pressures which sometimes equaled and even exceeded the subject's normal efforts. The voluntary muscles are thus in harmony with the approaching general sexual avalanche.

With regard to the relationship of detumescence to the blood-pressure Haig remarks: "I think that as the sexual act produces low and falling blood-pressure, it will of necessity relieve conditions which are due to high and rising blood-pressure, such, for instance, as mental depression and bad temper; and, unless my observation deceives me, we have here a connection between conditions of high blood-pressure, with mental and bodily depression, and the act of masturbation, for this act will relieve those conditions, and will tend to be practiced for this purpose."

A medical correspondent speaks of subjective feelings of temperature coming over the body from 20 to 24 hours after congress, and marked by sensations of cooling of body and glow of cheeks. In another case, though lassitude appears on the second day after congress, the first day after is marked by a notable increase in mental and physical activity.

The germ cell never comes into the sphere of consciousness and cannot therefore concern us in the psychological study of the phenomena of the sexual instinct. But it is otherwise with the sperm cell, and the seminal fluid has a relationship, both direct and indirect, to psychic phenomena which it is now necessary to discuss.

While the spermatozoa are formed in the glandular tissue of the testes, the seminal fluid as finally emitted in detumescence is not a purely testicular product, but is formed by mixture with the fluids poured out at or before detumescence by various glands which open into the urethra, and notably the prostate.^[129] This is a purely sexual gland, which in animals only becomes large and active during the breeding season, and may even be hardly distinguishable at other times; moreover, if the testes are removed in infancy, the prostate remains rudimentary, so that during recent years removal of the testes has been widely advocated and practiced for that hypertrophy of the prostate which is sometimes a distressing ailment of old age. It is the prostatic fluid, according to Fürbringer, which imparts its characteristic odor to semen. It appears, however, to be the main function of the prostatic fluid to arouse and maintain the motility of the spermatozoa; before meeting the prostatic fluid the spermatozoa are motionless; that fluid seems to furnish a thinner medium in which they for the first time gain their full vitality.^[130]

When at length the semen is ejaculated, it contains various substances which may be separated from it,^[131] and possesses various qualities, some of which have only lately been investigated, while others have evidently been known to mankind from a very early period. "When held for some time in the mouth," remarked John Hunter, "it produces a warmth similar to spices, which lasts some time."^[132] Possibly this fact first suggested that semen might, when ingested, possess valuable stimulant qualities, a discovery which has been made by various savages, notably by the Australian aborigines, who, in many parts of Australia, administer a potion of semen to dying or feeble members of the tribe.^[133] It is perhaps noteworthy that in Central Africa the testes of the goat are consumed as an aphrodisiac.^[134] In eighteenth century Europe, Schurig, in his Spermatologia, still found it necessary to discuss at considerable length the possible medical properties of human semen, giving many prescriptions which contained it.^[135] The stimulation produced by the ingestion of semen would appear to form in some cases a part of the attraction exerted by fellatio; De Sade emphasized this point; and in a case recorded by Howard semen appears to have acted as a stimulant for which the craving was as irresistible as is that for alcohol in dipsomania.^[136]

It must be remembered that the early history of this subject is more or less inextricably commingled with folk-lore practices of magical origin, not necessarily founded on actual observation of the physiological effects of consuming the semen or testes. Thus, according to W. H. Pearse (Scalpel, December, 1897), it is the custom in Cornwall for country maids to eat the testicles of the young male lambs when they are castrated in the spring, the survival, probably, of a very ancient religious cult. (I have not myself been able to hear of this custom in Cornwall.) In Burchard's Penitential (Cap. CLIV, Wasserschleben, op. cit., p. 660) seven years' penance is assigned to the woman who swallows her husband's semen to make him love her more. In the seventeenth century (as shown in William Salmon's London Dispensatory, 1678) semen was still considered to be good against witchcraft and also valuable as a love-philter, in which latter capacity its use still survives. (Bourke, Scatalogic Rites, pp. 343, 355.) In an earlier age (Picart, quoted by Crawley, The Mystic Rose, p. 109) the Manichæans, it is said, sprinkled their eucharistic bread with human semen, a custom followed by the Albigenses.

The belief, perhaps founded in experience, that semen possesses medical and stimulant virtues was doubtless fortified by the ancient opinion that the spinal cord is the source of this fluid. This was not only held by the highest medical authorities in Greece, but also in India and Persia.

The semen is thus a natural stimulant, a physiological aphrodisiac, the type of a class of drugs which have been known and cultivated in all parts of the world from time immemorial. (Dufour has discussed the aphrodisiacs used in ancient Rome, Histoire de la Prostitution, vol. II, ch. 21.) It would be vain to attempt to enumerate all the foods and medicaments to which has been ascribed an influence in heightening the sexual impulse. (Thus, in the sixteenth century, aphrodisiacal virtues were attributed to an immense variety of foods by Liébault in his Thresor des Remèdes Secrets pour les Maladies des Femmes, 1585, pp. 104, et seq.) A large number of them certainly have no such effect at all, but have obtained this credit either on some magical ground or from a mistaken association. Thus the potato, when first introduced from America, had the reputation of being a powerful aphrodisiac, and the Elizabethan dramatists contain many references to this supposed virtue. As we know, potatoes, even when taken in the largest doses, have not the slightest aphrodisiac effect, and the Irish peasantry, whose diet consists very largely of potatoes, are even regarded as possessing an unusually small measure of sexual feeling. It is probable that the mistake arose from the fact that potatoes were originally a luxury, and luxuries frequently tend to be regarded as aphrodisiacs, since they are consumed under circumstances which tend to arouse the sexual desires. It is possible also that, as has been plausibly suggested, the misunderstanding may have been due to sailors—the first to be familiar with the potato—who attributed to this particular element of their diet ashore the generally stimulating qualities of their life in port. The eryngo (Eryngium maritimum), or sea holly, which also had an erotic reputation in Elizabethan times, may well have acquired it in the same way. Many other vegetables have a similar reputation, which they still retain. Thus onions are regarded as aphrodisiacal, and were so regarded by the Greeks, as we learn from Aristophanes. It is noteworthy that Marro, a reliable observer, has found that in Italy, both in prisons and asylums, lascivious people are fond of onions (La Pubertà, p. 297), and it may perhaps be worth while to recall the observation of Sérieux that in a woman in whom the sexual instinct only awoke in middle age there was a horror of leeks. In some countries, and especially in Belgium, celery is popularly looked upon as a sexual stimulant. Various condiments, again, have the same reputation, perhaps because they are hot and because sexual desire is regarded, rightly enough, as a kind of heat. Fish—skate, for instance, and notably oysters and other shellfish—are very widely regarded as aphrodisiacs, and Kisch attributes this property to caviar. It is probable that all these and other foods which have obtained this reputation, in so far as they have any action whatever on the sexual appetite, only possess it by virtue of their generally nutritious and stimulating qualities, and not by the presence of any special principle having a selective action on the sexual sphere. A beefsteak is probably as powerful a sexual stimulant as any food; a nutritious food, however, which is at the same time easily digestible, and thus requiring less expenditure of energy for its absorption, may well exert a specially rapid and conspicuous stimulant effect. But it is not possible to draw a line, and, as Aquinas long since said, if we wish to maintain ourselves in a state of purity we shall fear even an immoderate use of bread and water.

More definitely aphrodisiacal effects are produced by drugs, and especially by drugs which in large doses are poisons. The aphrodisiac with the widest popular reputation is cantharides, but its sexually exciting effects are merely an accidental result of its action in causing inflammation of the genito-urinary passage, and it is both an uncertain and a dangerous result, except in skillful hands and when administered in small doses. Nux vomica (with its alkaloid strychnia), by virtue of its special action on the spinal cord, has a notably pronounced effect in heightening the irritability of the spinal ejaculatory center, though it by no means necessarily exerts any strengthening influence. Alcohol exerts a sexually exciting effect, but in a different manner; it produces little stimulation of the cord and, indeed, even paralyzes the lumbar sexual center in large doses, but it has an influence on the peripheral nerve-endings and on the skin, and also on the cerebral centers, tending to arouse desire and to diminish inhibition. In this latter way, as Adler remarks, it may, in small doses, under some circumstances, be beneficial in men with an excessive nervousness or dread of coitus, and women, in whom orgasm has been difficult to reach, have frequently found this facilitated by some previous indulgence in alcohol. The aphrodisiac effect of alcohol seems specially marked on women. But against the use of alcohol as an aphrodisiac it must be remembered that it is far from being a tonic to detumescence, at all events in men, and that there is much evidence tending to show that not only chronic alcoholism, but even procreation during intoxication is perilous to the offspring (see, e.g., Andriezen, Journal of Mental Science, January, 1905, and cf. W. C. Sullivan, "Alcoholism and Suicidal Impulses," ib., April, 1898, p. 268); it may be added that Bunge has found a very high proportion of cases of immoderate use of alcohol in the fathers of women unable to suckle their infants (G. von Bunge, Die Zunehmende Unfähigkeit der Frauen ihre Kinder zu Stillen, 1903) while even an approximation to the drunken state is far from being a desirable prelude to the creation of a new human being. It is obvious that those who wish, for any reason, to cultivate a strict chastity of thought and feeling would do well to avoid alcohol altogether, or only in its lightest forms and in moderation. The aphrodisiacal effects of wine have long been known; Ovid refers to them (e.g., Ars Am., Bk. III, 765). Clement of Alexandria, who was something of a man of science as well as a Christian moralist, points out the influence of wine in producing lasciviousness and sexual precocity. (Pædagogus, Bk. II, Chapter II). Chaucer makes the Wife of Bath say in the Wife of Bath's Prologue:—

Alcohol, as Chaucer pointed out, comes to the aid of the man, who is unscrupulous in his efforts to overcome a woman, and this not merely by virtue of its aphrodisiacal effects, and the apparently special influence which it seems to exert on women, but also because it lulls the mental and emotional characteristics which are the guardians of personality. A correspondent who has questioned on this point a number of prostitutes he has known, writes: "Their accounts of the first fall were nearly always the same. They got to know a 'gentleman,' and on one occasion they drank too much; before they quite realized what was happening they were no longer virgins." "In the mental areas, under the influence of alcohol," Schmiedeberg remarks (in his Elements of Pharmacology), "the finer degrees of observation, judgment, and reflection are the first to disappear, while the remaining mental functions remain in a normal condition. The soldier acts more boldly because he notices dangers less and reflects over them less; the orator does not allow himself to be influenced by any disturbing side-considerations as to his audience, hence he speaks more freely and spiritedly; self-consciousness is lost to a very great extent, and many are astounded at the ease with which they can express their thoughts, and at the acuteness of their judgment in matters which, when they are perfectly sober, with difficulty reach their minds; and then afterwards they are ashamed at their mistakes."

The action of opium in small doses is also to some extent aphrodisiacal; it slightly stimulates both the brain and the spinal cord, and has sensory effects on the skin like alcohol; these effects are favored by the state of agreeable dreaminess it produces. In the seventeenth century Venette (La Génération de l'Homme, Part II, Chapter V) strongly recommended small doses of opium, then little known, for this purpose; he had himself, he says, in illness experienced its joys, "a shadow of those of heaven." In India opium (as well as cannabis indica) has long been a not uncommon aphrodisiac; it is specially used to diminish local sensibility, delaying the orgasm and thus prolonging the sexual act. (W. D. Sutherland, "De Impotentia," Indian Medical Gazette, January, 1900). Its more direct and stimulating influence on the sexual emotions seems indicated by the statement that prostitutes are found standing outside the opium-smoking dens of Bombay, but not outside the neighboring liquor shops. (G. C. Lucas, Lancet, February 2, 1884.) Like alcohol, opium seems to have a marked aphrodisiacal effect on women. The case is recorded of a mentally deranged girl, with no nymphomania though she masturbated, who on taking small doses of opium at once showed signs of nymphomania, following men about, etc. (American Journal Obstetrics, May, 1901, p. 74.) It may well be believed that opium acts beneficially in men when the ejaculatory centers are weak but irritable; but its actions are too widespread over the organism to make it in any degree a valuable aphrodisiac. Various other drugs have more or less reputation as aphrodisiacs; thus bromide of gold, a nervous and glandular stimulant, is said to have as one of its effects a heightening of sexual feeling. Yohimbin, an alkaloid derived from the West African Yohimbehe tree, has obtained considerable repute during recent years in the treatment of impotence; in some cases (see, e.g., Toff's results, summarized in British Medical Journal, February 18, 1905) it has produced good results, apparently by increasing the blood supply to the sexual organs, but has not been successful in all cases or in all hands. It must always be remembered that in cases of psychical impotence suggestion necessarily exerts a beneficial influence, and this may work through any drug or merely with the aid of bread pills. All exercise, often even walking, may be a sexual stimulant, and it is scarcely necessary to add that powerful stimulation of the skin in the sexual sphere, and more especially of the nates, is often a more effective aphrodisiac than any drug, whether the irritation is purely mechanical, as by flogging, or mechanico-chemical, as by urtication or the application of nettles. Among the Malays (with whom both men and women often use a variety of plants as aphrodisiacs, according to Vaughan Stevens) Breitenstein states (21 Jahre in India, Theil I, p. 228) that both massage and gymnastics are used to increase sexual powers. The local application of electricity is one of the most powerful of aphrodisiacs, and McMordie found on applying one pole to a uterine sound in the uterus and the other to the abdominal wall that in the majority of healthy women the orgasm occurred.

Among anaphrodisiacs, or sexual sedatives, bromide of potassium, by virtue of its antidotal relationship to strychnia, is one of the drugs whose action is most definite, though, while it dulls sexual desire, it also dulls all the nervous and cerebral activities. Camphor has an ancient reputation as an anaphrodisiac, and its use in this respect was known to the Arabs (as may be seen by a reference to it in the Perfumed Garden), while, as Hyrtl mentions (loc. cit. ii, p. 94), rue (Ruta graveolens) was considered a sexual sedative by the monks of old, who on this account assiduously cultivated it in their cloister gardens to make vinum rutæ. Recently heroin in large doses (see, e.g., Becker, Berliner Klinische Wochenschrift, November 23, 1903) has been found to have a useful effect in this direction. It may be doubted, however, whether there is any satisfactory and reliable anaphrodisiac. Charcot, indeed, it is said, used to declare that the only anaphrodisiac in which he had any confidence was that used by the uncle of Heloïse in the case of Abelard. "Cela (he would add with a grim smile) tranche la difficulte."

If semen is a stimulant when ingested, it is easy to suppose that it may exert a similar action on the woman who receives it into the vagina in normal sexual congress. It is by no means improbable that, as Mattei argued in 1878, this is actually the case. It is known that the vagina possesses considerable absorptive power. Thus Coen and Levi, among others, have shown that if a tampon soaked in a solution of iodine is introduced into the vagina, iodine will be found in the urine within an hour. And the same is true of various other substances.^[137] If the vagina absorbs drugs it probably absorbs semen. Toff, of Braila (Roumania), who attaches much importance to such absorption, considers that it must be analogous to the ingestion of organic extractives. It is due to this influence, he believes, that weak and anæmic girls so often become full-blooded and robust after marriage, and lose their nervous tendencies and shyness.^[138]

It is, however, most certainly a mistake to suppose that the beneficial influence of coitus on women is exclusively, or even mainly, dependent upon the absorption of semen. This is conclusively demonstrated by the fact that such beneficial influence is exerted, and in full measure, even when all precautions have been taken to avoid any contact with the semen. In so far as coitus reservatus or interruptus may lead to haste or discomfort which prevents satisfactory orgasm on the part of the woman, it is without doubt a cause of defective detumescence and incomplete satisfaction. But if orgasm is complete the beneficial effects of coitus follow even if there has been no possibility of the absorption of semen. Even after coitus interruptus, if it can be prolonged for a period long enough for the woman to attain full and complete satisfaction, she is enabled to experience what she may describe as a feeling of intoxication, lasting for several hours. It is in the action of the orgasm itself, and the vascular, secretory, and metabolic activities set up by the psychic and nervous influence of coitus with a beloved person, that we must seek the chief key to the effects produced by coitus on women, however these effects may possibly be still further heightened by the actual absorption of semen.^[139]

The positive action of semen, or rather of the testicular products, has been much investigated during recent years, and appears on the whole to be demonstrated. The notable discovery by Brown-Séquard, a quarter of a century ago, that the ingestion of the testicular juices in states of debility and senility acted as a beneficial stimulant and tonic, opened the way to a new field of therapeutics. Many investigators in various countries have found that testicular extracts, and more especially the spermin as studied by Poehl,^[140] and by him regarded as a positive katalysator or accelerator of metabolic processes, exert a real influence in giving tone to the heart and other muscles, and in improving the metabolism of the tissues even when all influences of mental suggestion have been excluded.^[141]

As the ovaries are strictly analogous to the testes, it was surmised that ovarian extract might prove a drug equally valuable with testicular products. As a matter of fact, ovarian extract, in the form of ovarin, etc., would seem to have proved beneficial in various disorders, more especially in anæmia and in troubles due to the artificial menopause. In most conditions, however, in which it has been employed the results are doubtful or uncertain, and some authorities believe that the influence of suggestion plays a considerable part here.

There is, however, another use which is subserved by the testicular products, a use which may indeed be said to be implied in those uses to which reference has already been made, but is yet historically the latest to be realized and studied. It was not until 1869 that Brown-Séquard first suggested that an important secretion was elaborated by the ductless glands and received into the circulation, but that suggestion proved to be epoch-making. If these glandular secretions are so valuable when administered as drugs to other persons, must they not be of far greater value when naturally secreted and poured out into the circulation in the living body? It is now generally believed, on the basis of a large and various body of evidence, that this is undoubtedly so. In a very crude form, indeed, this belief is by no means modern. In opposition to the old writers who were inclined to regard the semen as an excretion which it was beneficial to expel, there were other ancient authorities who argued that it was beneficial to retain it as being a vital fluid which, if reabsorbed, served to invigorate the body. The great physiologist, Haller, in the middle of the eighteenth century, came very near to the modern doctrine when he stated in his Elements of Physiology that the sperm accumulated in the seminical vesicles is pumped back into the blood, and thus produces the beard and the hair together with the other surprising changes of puberty which are absent in the eunuch. The reabsorption of semen can scarcely be said to be a part of the modern physiological doctrine, but it is at least now generally held that the testes secrete substances which pass into the circulation and are of immense importance in the development of the organism.

The experiments of Shattock and Seligmann indicate that the semen and its reabsorption in the seminal vesicles, or the nervous reactions produced by its presence, can have no part in the formation of secondary sexual characters. These investigators occluded the vas deferens in sheep by ligature, at an early age, rendering them later sterile though not impotent. The secondary sexual characters appeared as in ordinary sheep. Spermatogenesis, these inquirers conclude, may be the initial factor, but the results must be attributed to the elaboration by the testicles of an internal secretion and its absorption into the general circulation.^[142]

When animals are castrated there is enlargement of the ductless glands in the body, notably the thyroid and the suprarenal capsules.^[143] It is evident, therefore, that the secretions of these ductless glands are in some degree compensatory to those of the testes. But this compensatory action is inadequate to produce any sexual development in the absence of the testes.

We see, therefore, how extremely important is the function of the testis. Its significance is not alone for the race, it is not simply concerned with the formation of the spermatozoa which share equally with the ova the honor of making the mankind of the future. It also has a separate and distinct function which has reference to the individual. It elaborates those internal secretions which stimulate and maintain the physical and mental characters, constituting all that is most masculine in the male animal, all that makes the man in distinction from the eunuch. Among various primitive peoples, including those of the European race whence we ourselves spring, the most solemn form of oath was sworn by placing the hand on the testes, dimly recognized as the most sacred part of the body. A crude and passing phase of civilization has ignorantly cast ignominy upon the sexual organs; the more primitive belief is now justified by our advancing knowledge.

In these as in other respects the ovaries are precisely analogous to the testes. They not only form the ova, but they elaborate for internal use a secretion which develops and maintains the special physical and mental qualities of womanhood, as the testicular secretion those of manhood. Moreover, as Cecca and Zappi found, removal of the ovaries has exactly the same effect on the abnormal development of the other ductless glands as has removal of the testes. It is of interest to point out that the internal secretion of the ovaries and its important functions seem to have been suggested before any other secretion than the sperm was attributed to the testes. Early in the nineteenth century Cabanis argued ("De l'Influence des Sexes sur le Caractère des Idées et des Affections Morales," Rapport du Physique et du Moral de l'Homme, 1824, vol. ii, p. 18) that the ovaries are secreting glands, forming a "particular humor" which is reabsorbed into the blood and imparts excitations which are felt by the whole system and all its organs.

[129]

The composite character of the semen was recognized by various old authors, some of whom said, (e.g., Wharton) that it had three constituents, which they usually considered to be: (1) The noblest and most essential part, from the testicles; (2) a watery element from the vesiculæ; (3) an oily element from the prostate.

In a similar but somewhat more precise manner Dufougère has argued ("La Chlorose, ses rapports avec le marriage, son traitement par le liquide orchitique," Thèse de Bordeaux, 1902) that semen when absorbed by the vagina stimulates the secretion of the ovaries and thus exerts an influence over the blood in anæmia; in this way he seeks to explain why it is that coitus is the best treatment for chlorosis.

[139]

In this connection I may refer to an interesting and suggestive paper by Harry Campbell on "The Craving for Stimulants" (Lancet, October 21, 1899). No reference is made to coitus, but the author discusses stimulants as normal and beneficial products of the organism, and deals with the nature of the "physiological intoxication" they produce.

[140]

Spermin was first discovered in the sperm by Schreiner in 1878; it has also been found in the thyroid, ovaries and various other glands. "The spermin secreting and elaborating organs," Howard Kelly remarks (British Medical Journal, January 29, 1898), "may be called the apothecaries' of the body, secreting many important medicaments, much more active and more accurately representing its true wants than artificially administered drugs."

The Aptitude for Detumescence—Is There an Erotic Temperament?—The Available Standards of Comparison—Characteristics of the Castrated—Characteristics of Puberty—Characteristics of the State of Detumescence—Shortness of Stature—Development of the Secondary Sexual Characters—Deep Voice—Bright Eyes—Glandular Activity—Everted Lips—Pigmentation—Profuse Hair—Dubious Significance of Many of These Characters.

What, if any, are the indications which the body generally may furnish as to the individual's aptitude and vigor for the orgasm of detumescence? Is there an erotic temperament outwardly and visibly displayed? That is a question which has often occupied those who have sought to penetrate the more intimate mysteries of human nature, and since we are here concerned with human beings in their relationship to the process of detumescence, we cannot altogether pass over this question, difficult as it is to discuss it with precision.

The old physiognomists showed much confidence in dealing with the matter. Possibly they had more opportunities for observation than we have, since they often wrote in days when life was lived more nakedly than among ourselves, but their descriptions, while sometimes showing much insight, are inextricably mixed up with false science and superstition.

In the De Secretis Mulierum, wrongly attributed to Albertus Magnus, we find a chapter entitled "Signa mulieris calidæ naturæ et quæ coit libenter," which may be summarized here. "The signs," we are told, "of a woman of warm temperament, and one who willingly cohabits are these: youth, an age of over 12, or younger, if she has been seduced, small, high breasts, full and hard, hair in the usual positions; she is bold of speech, with a delicate and high voice, haughty and even cruel of disposition, of good complexion, lean rather than stout, inclined to like drinking. Such a woman always desires coitus, and receives satisfaction in the act. The menstrual flow is not abundant nor always regular. If she becomes pregnant the milk is not abundant. Her perspiration is less odorous than that of the woman of opposite temperament; she is fond of singing, and of moving about, and delights in adornments if she has any."

Polemon, in his Sulla Physionomia, has given among the signs of libidinous impulse: knees turned inwards, abundance of hairs on the legs, squint, bright eyes, a high and strident voice, and in women length of leg below the knee. Aristotle had mentioned among the signs of wantonness: paleness, abundance of hair on the body, thick and black hair, hairs covering the temples, and thick eyelids.

In the seventeenth century Bouchet, in his Serées (Troisième Serée), gave as the signs of virility which indicated that a man could have children: a great voice, a thick rough black beard, a large thick nose.

G. Tourdes (Art. "Aphrodisie," Dictionnaire Encyclopédique des Sciences Médicales) thus summarized the ancient beliefs on this subject: "The erotic temperament has been described as marked by a lean figure, white and well-ranged teeth, a developed hairy system, a characteristic voice, air, and expression, and even a special odor."

In approaching the question of the general physical indications of a special aptitude to the manifestation of vigorous detumescence, the most obvious preliminary would seem to be a study of the castrated. If we know the special peculiarities of those who by removal of the sexual glands at a very early age have been deprived of all ability to present the manifestations of detumescence, we shall probably be in possession of a type which is the reverse of that which we may expect in persons of a vigorously erotic temperament.

The most general characteristics of eunuchs would appear to be an unusual tendency to put on fat, a notably greater length of the legs, absence of hair in the sexual and secondary sexual regions, a less degree of pigmentation, as noted both in the castrated negro and the white man, a puerile larynx and puerile voice. In character they are usually described as gentle, conciliatory, and charitable.

There can be little doubt that castration in man tends to lead to lengthening of the legs (tibia and fibula) at puberty, from delayed ossification of the epiphyses. The hands and feet are also frequently longer and sometimes the forearms. At the same time the bones are more slender. The pelvis also is narrower. The eunuchs of Cairo are said to be easily seen in a crowd from their tall stature. (Collineau, quoting Lortet, Revue Mensuelle de l'Ecole d'Anthropologie, May, 1896.) The castrated Skoptzy show increased stature, and, it seems, large ears, with decreased chest and head (L. Pittard, Revue Scientifique, June 20, 1903.) Féré shows that in most of these respects the eunuch resembles beardless and infantile subjects. ("Les Proportions des Membres et les Caractères Sexuels," Journal de l'Anatomie et de la Physiologie, November-December, 1897.) Similar phenomena are found in animals generally. Sellheim, carefully investigating castrated horses, swine, oxen and fowls, found retardation of ossification, long and slender extremities, long, broad, but low skull, relatively smaller pelvis and small thorax. ("Zur Lehre von den Sekundären Geschlechtscharakteren," Beiträge zur Geburtshülfe und Gynäkologie, 1898, summarized in Centralblatt für Anthropologie, 1900, Heft IV.)

As regards the mental qualities and moral character of the castrated, Griffiths considers that there is an undue prejudice against eunuchs, and refers to Narses, who was not only one of the first generals of the Roman Empire, but a man of highly estimable character. (Lancet, March 30, 1895.) Matignon, who has carefully studied Chinese eunuchs, points out that they occupy positions of much responsibility, and, though regarded in many respects as social outcasts, possess very excellent and amiable moral qualities (Archives Cliniques de Bordeaux, May, 1896.) In America Everett Flood finds that epileptics and feeble-minded boys are mentally and morally benefited by castration. ("Notes on the Castration of Idiot Children," American Journal of Psychology, January, 1899.) It is often forgotten that the physical and psychic qualities associated with and largely dependent on the ability to experience the impulse of detumescence, while essential to the perfect man, involve many egoistic, aggressive and acquisitive characteristics which are of little intellectual value, and at the same time inimical to many moral virtues.

We have a further standard—positive this time rather than negative—to aid us in determining the erotic temperament: the phenomena of puberty. The efflorescence of puberty is essentially the manifestation of the ability to experience detumescence. It is therefore reasonable to suppose that the individuals in whom the special phenomena of puberty develop most markedly are those in whom detumescence is likely to be most vigorous. If such is the case we should expect to find the erotic temperament marked by developed larynx and deep voice, a considerable degree of pigmentary development in hair and skin, and a marked tendency to hairiness; while in women there should be a pronounced growth of the breasts and pelvis.^[144]

There is yet another standard by which we may measure the individual's aptitude for detumescence: the presence of those activities which are most prominently brought into play during the process of detumescence. The individual, that is to say, who is organically most apt to manifest the physiological activities which mainly make up the process of detumescence, is most likely to be of pronounced erotic temperament.

"Erotic persons are of motor type," remark Vaschide and Vurpas, "and we may say generally that nearly all persons of motor type are erotic." The state of detumescence is one of motor and muscular energy and of great vascular activity, so that habitual energy of motor response and an active circulation may reasonably be taken to indicate an aptitude for the manifestation of detumescence.

These three types may be said, therefore, to furnish us valuable though somewhat general indications. The individual who is farthest removed from the castrated type, who presents in fullest degree the characters which begin to emerge at the period of puberty, and who reveals a physiological aptitude for the vigorous manifestation of those activities which are called into action during detumescence, is most likely to be of erotic temperament. The most cautious description of the characteristics of this temperament given by modern scientific writers, unlike the more detailed and hazardous descriptions of the early physiognomists, will be found to be fairly true to the standards thus presented to us.

The man of sexual type, according to Biérent (La Puberté, p. 148), is hairy, dark and deep-voiced.

"The men most liable to satyriasis," Bouchereau states (art. "Satyriasis," Dictionnaire Encyclopédique des Sciences Médicales), "are those with vigorous nervous system, developed muscles, abundant hair on body, dark complexion, and white teeth."

Mantegazza, in his Fisiologia del Piacere, thus describes the sexual temperament: "Individuals of nervous temperament, those with fine and brown skins, rounded forms, large lips and very prominent larynx enjoy in general much more than those with opposite characteristics. A universal tradition," he adds, "describes as lascivious humpbacks, dwarfs, and in general persons of short stature and with long noses."

In a case of nymphomania in a young woman, described by Alibert (and quoted by Laycock, Nervous Diseases of Women, p. 28) the hips, thighs and legs were remarkably plump, while the chest and arms were completely emaciated. In a somewhat similar case described by Marc in his De la Folie a peasant woman, who from an early age had experienced sexual hyperæsthesia, so that she felt spasmodic voluptuous feelings at the sight of a man, and was thus the victim of solitary excesses and of spasmodic movements which she could not repress, the upper part of the body was very thin, the hips, legs and thighs highly developed.

In his work on Uterine and Ovarian Inflammation (1862, p. 37) Tilt observes: "The restless, bashful eye, and changing complexion, in presence of a person of the opposite sex, and a nervous restlessness of body, ever on the move, turning and twisting on sofa or chair, are the best indications of sexual temperament."

An extremely sensual little girl of 8, who was constantly masturbating when not watched, although brought up by nuns, was described by Busdraghi (Archivio di Psichiatria, fas. i, 1888, p. 53) as having chestnut hair, bright black eyes, an elevated nose, small mouth, pleasant round face, full colored cheeks, and plump and healthy aspect.

A highly intelligent young Italian woman with strong and somewhat perverted sexual impulses is described as of attractive appearance, with olive complexion, small black almond-shaped eyes, dilated pupils, oblique thin eyebrows, very thick black hair, rather prominent cheek-bones, largely developed jaw, and with abundant down on lower part of cheeks and on upper lip. (Archivio di Psichiatria, 1899, fasc. v-vi.)

As the type of the sensual woman in word and act, led by her passions to commit various sexual offenses, Ottolenghi describes (Archivio di Psichiatria, vol. xii, fasc. v-vi, p. 496) a woman of 32 who attempted to kill her lover. The daughter of parents who were neurotic and themselves very erotic, she was a highly intelligent and vivacious woman, with a pleasing and open face, very thick dark chestnut hair, large cheek-bones, adipose buttocks almost resembling those of a Hottentot, and very thick pubic hair. She was very fond of salt things. Sexual inclination began at the age of 7.

Adler and Moll remark, very truly, that, so far at least as women are concerned, sexual anæsthesia or sexual proclivity cannot be unfailingly read on the features. Every woman desires to please, and coquetry is the sign of a cold, rather than of an erotic temperament.^[145] It may be added that a considerable degree of congenital sexual anæsthesia by no means prevents a woman from being beautiful and attractive, though it must probably still always be said that, as Roubaud points out,^[146] the woman of cold and intellectual temperament, the "femme de tête," however beautiful and skillful she may be, cannot compete in the struggle for love with the woman whose qualities are of the heart and of the emotions. But it seems sufficiently clear that the practical observations of skilled and experienced observers agree in attributing to persons of erotic type certain general characteristics which accord with those negative and positive standards we may frame on the basis of castration, of puberty, and of detumescence. It may be worth while to note a few of these characteristics briefly.

The abnormal lengthening of the long bones at the age of puberty in the castrated is, as we have seen, very pronounced. There is little tendency to associate length of limb with an erotic temperament, and a certain amount of data as well as of more vague opinion points in the opposite direction. The Arabs would appear to believe that it is short rather than tall people in whom the sexual instinct is strongly developed, and we read in the Perfumed Garden: "Under all circumstances little women love coitus more and evince a stronger affection for the virile member than women of a large size." In his elaborate investigation of criminals Marro found that prostitutes and women guilty of sexual offenses, as also male sexual offenders, tend to be short and thick set.^[147] In European folk-lore the thick, bull neck is regarded as a sign of strong sexuality.^[148] Mantegazza refers to a strong sexual temperament as being associated with arrest or disorder of bony development, and Marro suggests that the proverbial salacity of rachitic individuals may be due to an increased activity of the sexual organs.^[149] It may be added that acromegaly, with its excessive bony growths, tends to be associated with premature sexual involution.

A further point which is frequently mentioned in the case of women is the development of the chief secondary sexual regions: the pelvis and the breasts. It is, indeed, almost inevitable that there should be some degree of correlation between the aptitude for bearing children and the aptitude for experiencing detumescence. The reality of such a connection is not only evidenced by medical observations, but receives further testimony in popular beliefs. In Italy women with large buttocks are considered wanton, and among the South Slavs they are regarded as especially fruitful.^[150] Blumenbach asserted that precocious venery will enlarge the breasts, and believed that he had found evidence of this among young London prostitutes.^[151]

The association of the aptitude for detumescence with a tendency to a deep rather than to a high voice, both in men and women, has frequently been noted and has seldom been denied. The onset of puberty always affects the voice; in general, Biérent states, the more bass the voice is the more marked is the development of the sexual apparatus; "a very robust man, with very developed sexual organs, and very dark and abundant hairy system, a man of strong puberty in a word, is nearly always a bass."^[152] The influence of sexual excitement in deepening the voice is shown by the rules of sexual hygiene prescribed to tenors, while a bass has less need to observe similar precautions. In women every phase of sexual life—puberty, menstruation, coitus, pregnancy—tends to affect the voice and always by giving it a deeper character. The deepening of the voice by sexual intercourse was an ancient Greek observation, and Martial refers to a woman's good or bad singing as an index to her recent sexual habits. Prostitutes tend to have a deep voice. Venturi points out that married women preserve a fresh voice to a more advanced age than spinsters, this being due to the precocious senility in the latter of an unused function. Such a phenomenon indicates that the relationship of detumescence to the deepening of the voice is not quite simple. This is further indicated by the fact that in robust men abstinence still further deepens the voice (the monk of melodrama always has a bass voice), while excessive or precocious sexual indulgence tends to be associated with the same kind of puerile voice as is found in those persons in whom pubertal development has not been carried very far, or who are of what Griffiths terms eunuchoid type. Idiot boys, who are often sexually undeveloped, tend to have a high voice, while idiot girls (who often manifest marked sexual proclivities) not infrequently have a deep voice.^[153]

Bright dilated eyes are among the phenomena of detumescence, and are very frequently noted in persons of a pronounced erotic temperament. This is, indeed, an ancient observation, and Burton says of people with a black, lively, and sparkling eye, "without question they are most amorous," drawing his illustrations mostly from classic literature.^[154] Tardieu described the erotic woman as having bright eyes, and Heywood Smith states that the eyes of lascivious women resemble, though in a less degree, those of the insane.^[155] Sexual excitement is one among many causes—intellectual excitement, pain, a loud noise, even any sensory irritation—which produce dilatation of the pupils and enlargement of the palpebral fissure, with some protrusion of the eyeball. The influence of the sexual system upon the eye appears to be far less potent in men than in women.^[156] Sexual desire is, however, by no means the only irritant within the sexual sphere which may thus influence the eye; morbid irritations may produce the same effect. Milner Fothergill, in his book on Indigestion, vividly describes the appearance of the eyes sometimes seen in ovarian disorder: "The glittering flash which glances out from some female irides is the external indication of ovarian irritation, and 'the ovarian gleam' has features quite its own. The most marked instance which ever came under my notice was due to irritation in the ovaries, which had been forced down in front of the uterus and been fixed there by adhesions. Here there was little sexual proclivity, but the eyes were very remarkable. They flashed and glittered unceasingly, and at times perfect lightning bolts shot from them. Usually there is a bright glittering sheen in them which contrasts with the dead look in the irides of sexual excess or profuse uterine discharges."

The activity of the glandular secretions, and especially those of the skin, during detumescence, would lead us to expect that such secretory activity is an index to an aptitude for detumescence. As a matter of fact it is occasionally, though not frequently, noted by medical observers. It is stated that the erotic temperament is characterized by a special odor.^[157] The activity of the sweat-glands is seldom referred to by medical observers in describing persons of erotic temperament, although the descriptions of novelists not infrequently contain allusions to this point, and the literature of an earlier age shows that the tendency to perspiration, especially the moist hand, was regarded as a sure sign of a sensual temperament. "The moist-handed Madonna Imperia, a most rare and divine creature," remarks Lazarillo in Middleton's comedy Blurt, Master-Constable, to quote one of many allusions to this point in the Elizabethan drama.

The lips are sometimes noted as red and everted, perhaps thick^[158]; Tardieu remarked that the typically erotic woman has thick red lips. This corresponds with the characteristic type of the satyr in classic statues as in later paintings; his lips are always thick and everted. Fullness, redness, and eversion of the lips are correlated with good breathing, the absence of anæmia, laughter, a well-fleshed face.

This kind of mouth indicates, perhaps, not so much a congenitally erotic temperament, as an abandonment to impulse. The opposite type of mouth—with inverted, thin, and retracted lips—would appear to be found with especial frequency in persons who habitually repress their impulses on moral grounds. Any kind of effort to restrain involuntary muscular action may lead to retraction of the lips: the effort to overcome anger or fear, or even the resistance to a strong desire to urinate or defecate. In religious young men, however, it becomes habitual and fixed. I recall a small band of medical students, gathered together from a large medical school, who were accustomed to meet together for prayer and Bible-reading; the majority showed this type of mouth to a very marked degree: pale faces, with drawn, retracted lips. It may be termed the Christian or pious facies. It is much less frequently seen in religious women (unless of masculine type), doubtless because religion for women is in a much less degree than for men a moral discipline.

It may be added that an interesting form of this contraction of the lips, and one that is not purely repressive, is that which indicates the state of muscular tension associated with the impulse to guard and protect. In this form the contracted mouth is the index of tenderness, and is characteristic of the mother who is watching over the infant she is suckling at her breast. I have observed precisely the same expression in the face of a boy of 14 with a large congenital scrotal hernia; when the tumor was being examined his lower lip became retracted, well marked lines appearing from the angles downwards, though the upper lip retained its normal expression It was precisely the tender look we may see in the faces of mothers who are watching anxiously over their offspring, and the emotion is evidently the same in both cases: solicitude for a sensitive and tenderly guarded object.

The degree of pigmentation is clearly correlated with sexual vigor. "In general," Heusinger laid down, in 1823, "the quantity of pigment is proportional to the functional effectiveness of the genital organs." This connection is so profound that it may be traced very widely throughout the organic world.

The connection between pigmentation and sexual activity is very ancient. Even leaving out of account the wedding apparel of animals, nearly always gorgeous in scales and plumage and hair, the sexual orifice shows a more or less marked tendency to pigmentation during the breeding season from fishes upward, while in mammals the darker pigmentation of this region is a constant phenomenon in sexually mature individuals.^[159]

In the human species both the negative standard of castration and the positive standard of puberty alike indicate a correlation of this kind. Those individuals in whom puberty never fully develops and who are consequently said to be affected by infantilism, reveal a relative absence of pigment in the sexual centers which are normally pigmented to a high degree.^[160] Among those Asiatic races who extirpate the ovaries in young girls the skin remains white in the perineum, round the anus, and in the armpits.^[161] Even in mature women who undergo ovariotomy, as Kepler found, the pigmentation of the nipples and areola disappears, as well as of the perineum and anus, the skin taking on a remarkable whiteness.

Normally the sexual centers, and in a high degree the genital orifice, represent the maximum of pigmentation, and under some circumstances this is clearly visible even in infancy. Thus babies of mixed black and white blood may show no traces of negro ancestry at birth, but there will always be increased pigmentation about the external genitalia.^[162] The linea fusca, which reaches from the pubes to the navel and occasionally to the ensiform cartilage, is a line of sexual pigmentation sometimes regarded as characteristic of pregnancy, but as Andersen, of Copenhagen, has found by the examination of several hundred children of both sexes, it exists in a slight form in about 75 per cent. of young girls, and in almost as large a proportion of boys. But there is no doubt that it tends to increase with age as well as to become marked at pregnancy. At puberty there is a general tendency to changes in pigmentation; thus Godin found that in 28 per cent, adolescent changes occurred in the eyes and hair at this period, the hair becoming darker, though the eyes sometimes become lighter. Ammon, in his investigation of conscripts at the age of 20 (post, p. 196), discovered the significant fact that the eyes and hair darken pari passu with sexual development. In women, during menstruation, there is a general tendency to pigmentation; this is especially obvious around the eyes, and in some cases black rings of true pigment form in this position. Even the skin of the negro women of Loango sometimes becomes a few shades darker during menstruation.^[163] During pregnancy this tendency to pigmentation reaches its climax. Pregnancy constantly gives rise to pigmentation of the face, the neck, the nipples, the abdomen, and this is especially marked in brunettes.

This association of pigmentation and sexual aptitudes has been recognized in the popular lore of some peoples. Thus the Sicilians, who admire brown skin and have no liking either for a fair skin or light hair, believe that a white woman is incapable of responding to love. It is the brown woman who feels love; as it is said in Sicilian dialect: "Fimmina scura, fimmina amurusa."^[164]

The dependence of pigmentation upon the sexual system is shown by the fact that irritation of the genital organs by disease will frequently suffice to produce a high degree of pigmentation. This may the neck, the trunk, the hands. Simpson long since noted that uterine irritation apart from pregnancy may produce pigmentation of the areolæ of the nipples (Obstetric Works, vol. i, p. 345). Engelmann discussed the subject and gave cases, "The Hystero-Neuroses," pp. 124-139, in Gynæcological Transactions, vol. xii, 1887; and a summary of a memoir by Fouquet on this subject in La Gynécologie, February, 1903, will be found in British Medical Journal, March 28, 1903,

Of all physical traits vigor of the hairy system has most frequently perhaps been regarded as the index of vigorous sexuality. In this matter modern medical observations are at one with popular belief and ancient physiognomical assertions.^[165] The negative test of castration and the positive test of puberty point in the same direction.

It is at puberty that all the hair on the body, except that on the head, begins to develop; indeed, the very word "puberty" has reference to this growth as the most obvious sign of the whole process. When castration takes place at an early age all this development of pubescent hair is arrested. When the primary sexual organs are undeveloped the sexual hair is also undeveloped, as in a case, recorded by Plant,^[166] of a girl with rudimentary uterus and ovaries who had little or no axillary and pubic hair, although the hair of the head was long and strong.^[167]

The pseudo-Michael Scot among the Signa mulieris calidæ naturæ et quæ coit libenter stated that her hair, both on the head and body, is thick and coarse and crisp, and Della Porta, the greatest of the physiognomists, said that thickness of hair in women meant wantonness. Venette, in his Generation de l'Homme, remarked that men who have much hair on the body are most amorous. At a more recent period Roubaud has said that pubic hair in its quantity, color and curliness is an index of genital energy. A poor pilous system, on the other hand, Roubaud regarded as a probable though not an irrefragable proof of sexual frigidity in women. "In the cold woman the pilous system is remarkable for the languor of its vitality; the hairs are fair, delicate, scarce and smooth, while in ardent natures there are little curly tufts about the temples." (Traité de l'Impuissance, pp. 124, 523.) Martineau declared (Leçons sur les Déformations Vulvaires, p. 40) that "the more developed the genital organs the more abundant the hair covering them; abundance of hair appears to be in relation to the perfect development of the organs." Tardieu described the typically erotic woman as very hairy.

Bergh found that among 2200 young Danish prostitutes those who showed an unusual extension and amount of pubic hair included several women who were believed to be libidinous in a very high degree. (Bergh, "Symbolæ," etc., Hospitalstidende, August, 1894.) Moraglia, again, in Italy, in describing various women, mostly prostitutes, of unusually strong sexual proclivities, repeatedly notes very thick hair, with down on the face. (Archivio di Psichiatria, vol. xvi, fasc. iv-v.)

Marro, also, in Italy found that abundance of hair and down is especially marked in women who are guilty of infanticide (as also Pasini has found), though criminal women generally, in his experience, tend to have abnormally abundant hair. (Caratteri del Delinquenti, cap. XXII.) Lombroso finds that prostitutes generally tend to be hairy (Donna Delinquente, p. 320.)

A lad of 14, guilty of numerous crimes of violence having a sexual source, is described by Arthur Macdonald in America as having hair on the chest as well as all over the pubes. (A. Macdonald, Archives de L'Anthropologie Criminelle, January, 1893, p. 55.) The association of hairiness with abnormal sexuality in the weak-minded has been noted at Bicêtre (Recherches Cliniques sur l'Epilepsie, vol. xix, pp. 69, 77.)

Hypertrichosis universalis, a general hairiness of body, has been described by Cascella in a woman with very strong sexual desires, who eventually became insane. (Revista Mensile di Psichiatria, 1903, p. 408.) Bucknill and Tuke give the case of a religiously minded girl, with very strong and repressed sexual desires, who became insane; the only abnormal feature in her physical development was the marked growth of hair over the body.

Brantôme refers to a great lady known to him whose body was very hairy, and quotes a saying to the effect that hairy people are either rich or wanton; the lady in question, he adds, was both. (Brantôme, Vie des Dames Galantes, Discours II.)

De Sade, whose writings are now regarded as a treasure house of true observations in the domain of sexual psychology, makes the Rodin of Justine dark, with much hair and thick eyebrows, while his very sexual sister is described as dark, thin and very hairy. (Dühren, Der Marquis de Sade, third edition, p. 440.)

A correspondent who has always taken a special interest in the condition as regards hairiness of the women to whom he has been attracted, has sent me notes concerning a series of 12 women. It may be gathered from these notes that 5 women were neither markedly sexual nor markedly hairy (either as regards head or pubes), 6 cases both hairy and sexual, 1 was sexual and not hairy, none were hairy and not sexual. My correspondent remarks: "There may be women with scanty pubic hair possessing very strong sexual emotions. My own experience is quite the opposite." He has also independently reached the conclusion, arrived at by many medical observers and clearly suggested by some of the facts here brought together, that profuse hair frequently denotes a neurotic temperament.

It may be added that Mirabeau, as we learn from an anecdote told by an eyewitness and recorded by Legouvé, had a very hairy chest, while the same is recorded of Restif de la Bretonne.

It is a very ancient and popular belief that if a hairy man is not sensual he is strong: vir pilosus aut libidinosus aut fortis. The Greeks insisted on the hairy nates of Hercules, and Ninon de l'Enclos, when the great Condé shared her bed without touching her, remarked, on seeing his hairy body: "Ah, Monseigneur, que vous devez être fort!" It may be doubted whether there is any exact parallelism between muscular strength and hairiness, for strength is largely a matter of training, but there can be no doubt that hairiness really tends to be associated with a generally vigorous development of the body.

Although the observations concerning hairiness of body as an index of vigor, whether sexual or only generally physical, are so ancient, until recent years no attempts have been made to demonstrate on a large scale whether there is actually a correlation between hairiness and sexual or general development of the body. Some importance, therefore, attaches to Ammon's careful observations of many thousand conscripts in Baden. These observations fully justify this ancient belief, since they show that on the one hand the size of the testicles, and on the other hand girth of chest and stature, are correlated with hairiness of body.
