Endometriosis

DS00289, MY00554_IM00303-w7_endometriosisthu.jpg Endometriosis occurs when bits of the tissue that lines the uterus (endometrium) grow on other pelvic organs, such as the ovaries or fallopian tubes. Outside the uterus, endometrial tissue thickens and bleeds, just as the normal endometrium does during the menstrual cycle.
