Endometriosis is a condition in which tissue from the lining of the uterus, also called endometrium, grows outside the uterus. This growth can occur on the ovaries, fallopian tubes, intestines or other areas in the pelvis. This tissue acts just like the endometrium in accumulating blood during a woman’s monthly menses, but has no place to shed the blood at the end of the cycle. The accumulation of tissue and blood can cause inflammation and scarring, which can lead to other conditions like pelvic pain and infertility. Blood trapped in the ovaries may develop into benign cysts called endometriomas.

Between 25 and 50 percent of infertile women are estimated to have endometriosis. Endometriosis affects more than one million women in the United States and at this time, the exact cause of the condition is unknown.
