If a woman has had her ovaries removed for menopause, she will not have a major problem. If one or both ovaries are removed while she is still of childbearing age or if she is younger than forty-five, she may experience menopausal syndrome, such as hot flashes, sweating, memory loss, high blood cholesterol, osteoporosis, and other abnormal symptoms. The ovaries secrete estrogen, and premature removal of the ovaries will not only affect pregnancy, but may also affect the endocrine function of the ovaries. If women lose the endocrine function of the ovaries, they may experience premature aging. If abnormal symptoms occur, early estrogen and progesterone replacement therapy should be used to prevent the appearance of menopausal syndrome.
