What are the risks of oophorectomy?

Oophorectomy is a generally safe procedure that carries a small risk of complications, including infection, intestinal blockage and injury to internal organs. The risk of complications depends on how the procedure is performed.

But more concerning is the impact of losing the hormones supplied by your ovaries. If you have yet to undergo menopause, oophorectomy causes early menopause. Early menopause carries many risks, including:

• Bone thinning (osteoporosis). Removing your ovaries reduces the amount of bone-building estrogen your body produces. This may increase your risk of a broken bone.
• Discomforts of menopause. Hot flashes, vaginal dryness, sexual problems, sleep disturbance and sometimes cognitive changes can occur during menopause. Removing your ovaries doesn't mean you'll immediately have these problems, but it does mean that any menopausal symptoms you develop will occur earlier and are more likely to reduce your quality of life than if they occurred during natural menopause.
• Increased risk of heart disease. Your risk of heart disease may increase if you have your ovaries removed.
• Lingering risk of cancer. Prophylactic oophorectomy doesn't completely eliminate your risk of breast cancer or ovarian cancer. A type of cancer that looks and acts identical to ovarian cancer can develop after the ovaries and fallopian tubes are removed. The risk of this type of cancer, called primary peritoneal cancer, is low — much lower than the lifetime risk of ovarian cancer if the ovaries remain intact.

Prophylactic oophorectomy might relieve much of your anxiety about developing cancer, but this type of surgery can also take an emotional toll on you. Even if you didn't plan on having children, you might mourn the loss of your fertility.
