The outcome of an oophorectomy depends on the indication for surgery, the medical condition of the patient and the operating surgeon.
Oophorectomy is indicated for ovarian disease conditions and other systemic diseases like breast cancer. Removing the ovaries will not eliminate the cancer if it has already spread to other organs. Patients with ovarian cancer, therefore, routinely receive other forms of treatment like chemotherapy and/or radiation in addition to Oophorectomy.
Oophorectomy when performed for early ovarian cancers improves the prognosis and survival rates.
Endometriosis can be successfully treated with an Oophorectomy, although it often requires identification and treatment of other endometrial areas outside of the ovaries at the time of surgery. If both of the ovaries are removed, the women will no longer menstruate and will no longer be able to become pregnant. If one ovary or even just a portion of an ovary remains, she may still menstruate and may be able to become pregnant.
