In the natural process of menopause, a woman's ovaries stop releasing eggs and making the hormones estrogen and progesterone. When this occurs, a woman stops having her period and is no longer fertile.
Menopause can also occur after surgical removal of a woman's ovaries or following chemotherapy or hormone therapy for the treatment of breast cancer.
