It is a well known fact in the medical profession that the ovaries of the female exert upon her development an influence analogous to that which the testes exert on the development of the male. For that reason, a surgeon should, under no condition, remove both ovaries (sexual glands) unless they are diseased in such a way as to necessitate their complete removal in order to save the life of the individual. If a woman of twenty-five were to suffer the loss of both ovaries, she would go very early into a condition of senile decay. If a female before puberty is deprived of both ovaries, it leads her to develop masculine physical characteristics and her temperament is wholly lacking in those characteristics which, summed up, might, for the want of a better term, be called FEMININITY.
