Why it's done

An oophorectomy may be performed for:

• A tubo-ovarian abscess — a pus-filled pocket involving a fallopian tube and an ovary
• Ovarian cancer
• Endometriosis
• Noncancerous (benign) ovarian tumors or cysts
• Reducing the risk of ovarian cancer or breast cancer in those at increased risk
• Ovarian torsion — the twisting of an ovary
