Question: why do women and men have different hormones ?

Amy Cameron answered on 16 Jun 2015:

Men and women have different levels of hormones as their bodies are designed for some different functions especially in relation to reproduction. For example both men and women produce testosterone but men have over 12x the amount compared to women. Testosterone is needed for sexual drive and to maintain an erection in men. In women oestrogen, progesterone and the gonardotrophic hormones LH and FSH all change levels throughout a woman’s menstrual cycle in order to prepare the womb for an egg, to release an egg and to shed the uterine lining if an egg doesn’t implant. Men have oestrogen but at much lower levels but their function is not known. If they have too much they can develop ‘feminised’ features and lose their sex drive.
