Ovarian chocolate cysts, ovarian dysfunction, loss of fertility and other effects may occur 5 years after hysterectomy for adenomyosis. 1. Ovarian chocolate cysts: Adenomyosis may develop ovarian chocolate cysts after surgery if you choose to keep your ovaries when undergoing hysterectomy. Therefore, it is recommended that women should have regular ultrasound or color ultrasound observation of the uterus after the operation, and regular follow-up of the function of both ovaries. 2. Ovarian dysfunction: Hysterectomy may affect the blood supply to the ovaries, and the ovarian hormone secretion level may decrease, which may cause ovarian dysfunction or even early menopause symptoms. 3. Loss of fertility: the uterus is the only place where the fertilized egg can be deposited and develop. Therefore, after hysterectomy, the uterus can no longer provide a place for the fertilized egg to settle and develop, and women will lose their fertility completely. Regular checkups are required after hysterectomy.
