Depends. If the ovaries are removed at the same time as the uterus, a woman will suddenly begin menopause. If one or both ovaries are still functioning (premenopause) and they are not removed, a woman should not go into menopause until approximately the same time she would have anyway with natural menopause. That's an average age of 51, but with a lot of variability.
