Note (return) — ORGANIC DIFFERENCES IN THE SEXES

A comparison of the waste products of the body and of the quantity of materials consumed in the metabolic process indicates a relatively larger consumption of energy by man. It is stated that man produces more urine than woman in the following proportion: men, 1,000 to 2,000 grams daily; women, 1,000 to 1,400 grams. As age advances, the amount diminishes absolutely and relatively in proportion to the diminution of the energy of the metabolic process. A table prepared from adults of both sexes, twenty-five years of age, of the average weight of sixty kilograms, shows a larger proportion both of inorganic and organic substances in the urine of men.66 Milne Edwards has found that the bones of the male are slightly richer in inorganic substances than those of the female.67
