By Mayo Clinic staff

Adenomyosis is a condition in which tissue that normally lines the uterus (endometrium) also grows within the muscular walls of the uterus. This is most likely to happen late in your childbearing years and after you've had children.

Adenomyosis isn't the same as endometriosis — a condition in which the uterine lining becomes implanted outside the uterus — although women with adenomyosis often also have endometriosis. The cause of adenomyosis remains unknown, but the disease typically disappears after menopause. For women who experience severe discomfort from adenomyosis, there are treatments that can help, but hysterectomy is the only cure.

Although adenomyosis can be quite painful, the condition is generally harmless. Learn more about adenomyosis, including its signs and symptoms, when you should see a doctor and what the best treatment might be for you.
