Note DD — Chapter XXI · SEX-HYGIENE FOR ADULTS

Roubaud says that, initus interruptus causes in the woman voluptuous excitation without allowing the reception of the spermatic fluid into the organs. The desire and the copulative-voluptuousness awaken the sensibility of the womb and prepare it to receive the normal excitation of the sperma. If its arrival fails, the uterine sensibility, awakened by the erotic sensibility, reacts upon the mobility in a confused manner and causes unsuitable and irregular motions. If these manoeuvres are often repeated the woman eventually becomes a nervous wreck.
