Moreover, why would hormone therapy be prescribed for endometriosis?

Women prescribed contraceptives also report relief from pain. In general, the therapy contains two hormones-estrogen and progestin, a progesterone-like hormone. Women who can't take estrogen because of cardiovascular disease or a high risk of blood clots can use progestin-only pills to reduce menstrual flow.
