The effects of removing one side of the ovary on a woman over 40 on her normal life are relatively small. The effects of removing both sides of the ovary include inability to have children, menopause, and early onset of menopause. 1. Unilateral ovariectomy: after removing one ovary, women over 40 years old will have normal function of the other ovary, which will still secrete estrogen and progesterone periodically, and the uterine lining will shed periodically, so they will have normal menstruation and ovulation, which will have less impact on the patient’s life. 2. Inability to bear children: After the removal of both ovaries of women over 40 years old, the body will no longer secrete estrogen periodically, and will not be able to ovulate periodically, therefore, the fertility will usually be lost. 3. Menopause: After the removal of both ovaries, the hormone level in the body is out of balance, which will not stimulate the endometrium to proliferate and peel off cyclically, so there will be no more menstruation. 4. Early menopause: After removing both ovaries of women over 40 years old, the low level of estrogen in the body will lead to premature aging, early menopause, etc., and symptoms such as hot flashes, excessive sweating, mood changes, insomnia, etc. will appear. The effects of ovary removal in women over 40 vary from person to person, and it is recommended to consult a doctor for timely treatment after experiencing uncomfortable symptoms.
