Question

Whether a fetal structure develops looking like a penis or a clitoris depends mainly on what?​

Quizplus · Accepted Answer

The development of a fetus's genitalia depends mainly on the amount of testosterone present. If there is a high amount of testosterone, the structure will develop as a penis, while a low amount will result in a clitoris. Estradiol does play a role in genital development, but primarily as a modulator of the effects of testosterone. The ratio of estradiol to testosterone and the timing of their secretion can also affect genital development, but overall, testosterone is the main determining factor.
