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.
Removing the ovaries reduces her risk of ovarian cancer by 85 to 90 percent, but it will also put her into menopause immediately, at age 39, around a decade before the average woman enters menopause naturally. (The average age for menopause in the United States is 51, according to the National Institute on Aging.)
