At what age do women go through menopause?

Varies. The average age of menopause is age 51. However, every woman is different. A minority of women will go through menopause in their early 40s or even late 50s.
Menopause in Women. It all depends. This can vary widely among women. I would bet, however, that the females in your family have fairly similar stories on this front. Women often follow in their mother's and sister's foot steps. It is most commonly occurring in the 40s for most women.
