If the ovaries are surgically removed, a woman does not have a natural source of estrogen, and she enters surgical menopause, which can also be early menopause. Early natural menopause, on the other hand, occurs if a woman stops getting her period and her estrogen production drops before she is 45.
The average age of menopause is 51. The majority of women stop having periods somewhere between ages 45 to 55. The beginning stages of declining ovary function can begin years before that in some women. Others will continue to have menstrual periods into their late 50s.
