A key principle demonstrated by Turner's syndrome is that

ovaries are NOT necessary for development of the Mullerian system

Women are more likely to initiate sex during _______________, suggesting an influence of hormones on female sexual behavior.

ovulation

The prenatal development of the internal reproduces structures of the male requires

recreation of androgens

Menstruation is triggered by
