Endometriosis

Condition marked by the presence, growth, and function of the tissue that normally lines the uterus (endometrium) in such sites as within the uterine walls, the fallopian tubes, the ovaries, and other sites within the pelvis or, rarely, out of the pelvic region. Endometriosis is fairly common (est. 15% of women), especially in childless women and women who have children late in life. Symptoms depend on the size and location of the displaced tissue but commonly include painful menstruation, painful coitus, and sometimes painful urination and defaecation and premenstrual bleeding. Endometriosis is a common cause of infertility. Treatment includes analgesics to relieve pain, hormones to decrease the size and number of lesions and, in severe cases, surgery.
