The ovaries play a vital role for women as they have reproductive and endocrine functions, producing and expelling egg cells and secreting sex hormones. In some women, the removal of the ovaries is necessary due to ovarian disease, which can have a number of effects on the woman’s body. If the surgery is performed by removing the ovaries bilaterally, the uterus is often removed at the same time. After the surgery, the endocrine function of women naturally decreases rapidly until it disappears, and they cannot ovulate, stop menstruating, lose their fertility, experience menopause-like symptoms, and enter menopause prematurely. Some women with excessive psychological burden may show signs of depression and need to use hormone replacement therapy at this time; if one ovary is removed, the other ovary can play a compensatory role and can continue to produce egg cells and secrete sex hormones, and patients can have children normally after surgery, but because both ovaries produce eggs in turn, the chances of conception are theoretically reduced. In clinical practice, for young ovarian tumor patients, even if they have bilateral tumors, doctors will strive to perform ovarian tumor debulking in order to preserve some ovarian tissues and try to maintain the patient’s fertility and endocrine function.
