Endometriosis, a cause of female infertility, is a condition in which endometrial tissue grows outside the uterus. Many women with endometriosis have severe cramping during their menstrual period and experience pain during or after sexual intercourse. Research shows that endometriosis is more common in women with fertility problems and that pregnancy rates among women with endometriosis tend to be lower than that of the general population. A common question we hear at CWRC is: “Can women with endometriosis be treated successfully?”
