Endometriosis is a common but an enigmatic disease in which endometrial glands and stroma are found outside the uterus. Worldwide, 80 million women are affected by the disease. It has generally been accepted as a problem of reproductive ages and affects 6-10% of those women. It is more common in women with infertility. Moreover, since it is an estrogen dependent problem, it is generally believed that endometriosis connotes 'active ovarian function' and is 'healed' after the menopause. However, there are reports on endometriosis beyond the reproductive ages. In this article, endometriosis after the menopause will be discussed.
