The ovaries are almond-shaped and located on both sides of the womb in the lower abdomen region. They produce hormones that control the woman’s menstrual cycle and contain eggs. Oophorectomy can be performed alone in some cases, but it is mostly performed as a part of a larger operation for the removal of the uterus (hysterectomy) in women who have gone through menopause and in gender reassignment cases. The surgery is usually performed in conjunction with nearby fallopian tubes (salpingectomy). If the surgery to remove the ovaries involves the removal of the ovaries on both sides, the procedure is called a bilateral oophorectomy, and it is called unilateral oophorectomy if it involves the removal of one side. Oophorectomy is performed for gender reassignment, the removal of abscesses in the uterus or ovaries, a pus-filled sac in the fallopian tube or ovarian cancer, endometriosis (sagging of the lining of the uterus), benign ovarian tumors or cysts, for reducing the risk in women with a high risk of ovarian cancer or breast cancer, ovarian rotation. The doctor may instruct the patient to take medication to clean their digestive system. The patient must stop eating the day before surgery and limit fluid intake, stop taking certain medications and take antibiotics to prevent infections. There are two options as open surgery and laparoscopic surgery in this procedure, depending on the condition of the patient. Almost all women can return to their normal routine within six weeks after surgery.
