Menopause is a period in a woman’s life when the ovaries stop producing estrogen and progesterone. This change is caused by an imbalance between the production of estrogen and progesterone. During menopause, a woman’s body begins to produce fewer eggs than it did before.

The average age at which a woman reaches menopause is 52 years old. Some women experience menopause earlier than others, but no one knows why this happens.
