The ovaries may not shrink in the short term after hysterectomy, but may shrink over time because the uterine artery may be severed at the same time as the hysterectomy, and the ovarian artery is a branch of the uterine artery, so the blood vessels that nourish the ovaries may be affected to some extent after hysterectomy. In the short term, the ovarian function and size may not change significantly, but over time, the ovaries may slowly shrink, and ovarian function may diminish or even fail. Therefore, after hysterectomy, women may not have menopausal symptoms in the short term, but with the passage of time, there may be some hot flashes, sweating, memory loss and other abnormal menopausal symptoms, and it is recommended that estrogen supplementation and replacement therapy be carried out at the same time after hysterectomy.
