Diseases of the generative organs are of course distinctive in the two sexes. The tissues of the male being, as a rule, larger and firmer, they might be expected to offer more resistance to the external forces, but this is very doubtfully the case, and at nearly all periods of life the female is less susceptible to disease than the male. It is a remarkable fact that apparently in all lands, there are more male than female children born (in the proportion of 103-105 boys to 100 , girls). But this disproportion begins to be reduced at the very point of birth, by the fact that more males are still-born than females (in the proportion of 14: 10). This is apparently due to the fact that male children are on the average more bulky - especially have larger heads, than females, and are therefore more exposed to the accidents of parturition. Even after birth the females show less liability to disease, so that by the end of the first year the sexes are already equal in numbers. Throughout the remaining years of life the females are, at all ages, usually in the majority. Even the dangers of childbearing do not reverse the balance, as the risks are counterbalanced by the greater exposure of men, during the corresponding years of life, to accident and injury in the pursuance of their occupations.
