Endometriosis is a condition where tissue similar to the lining of the uterus is found outside of the uterine cavity (such as on the ovaries, fallopian tubes, or other pelvic structures). This tissue responds to the hormones that trigger the menstrual cycle so thickens and sheds like the cells found in the uterus. Below you may find medications used to treat or help with Endometriosis. More about Endometriosis
