Sex - Basic Aspects of Human Sexuality

The Role of Hormones:
What are the effects of the menopause on sexual behavior?

Usually beginning at age 50, a woman experiences her menopause, i.e. the cessation of menstruation. This happens because the ovaries gradually cease their hormone production. This does not necessarily mean a weakening of her sexual response. Indeed, the response may even be strengthened for psychosocial reasons, for example, because she no longer has to fear pregnancy.
