A few inaccuracies in your comment: Estrogen will induce breast and uterine cancers unless it is given with progesterone. Hardly zero side-effects. It is considered proper to only administer estrogen alone to women with severe symptoms of menopause. For the purpose of contraception, the COCP uses low levels which inhibit further hormone release by acting on the pituitary gland; it effectively simulates the state of pregnancy. Even this has risks especially for women with coagulation disorders. With regard to your comments about men receiving hormone supplementations: the problem here is that testosterone production doesn't actually decrease as you get older. Or at least, falling testosterone seems to be the result of, and not the cause of, age and lifestyle related changes and declines. This result was shared with my med school class by one of the principle investigators of the 2011 study in the links; I apologise for using science daily Links as I don't have access to research journals ATM http://www.webmd.com/healthy-aging/news/20110607/testosterone-decline-not-inevitable-with-age http://www.webmd.com/healthy-aging/news/20110607/testosteron... http://www.sciencedaily.com/releases/2011/06/110607121129.htm http://www.sciencedaily.com/releases/2011/06/110607121129.ht...
