Oophorectomy - Topic Overview

What is an oophorectomy?

Oophorectomy is the surgical removal of the ovaries, the part of a woman's reproductive system that stores and releases eggs for fertilization and produces female sex hormones.

Oophorectomy may be done alone or as part of a hysterectomy.

General Information About Ovarian Low Malignant Potential Tumors

Ovarian low malignant potential tumor is a disease in which abnormal cells form in the tissue covering the ovary. Ovarian low malignant potential tumors have abnormal cells that may become cancer, but usually do not. This disease usually remains in the ovary. When disease is found in one ovary, the other ovary should also be checked carefully for signs of disease. The ovaries are a pair of organs in the female reproductive system. They are in the pelvis, one on each side of the uterus (the hollow,...

Oophorectomy is often needed when pelvic disease, such as ovarian cancer, is present. And it is sometimes recommended when the hormones produced by the ovaries are making a disease such as breast cancer or severe endometriosis worse.

In some cases the ovaries are removed to try to reduce the possibility of developing a future disease, such as ovarian cancer. This is called a prophylactic oophorectomy.

What are the reasons to have an oophorectomy?

About 10 out of 100 women who have a hysterectomy also have a condition or disease that may increase the need for an oophorectomy.1 These conditions or diseases include:

  • Heredity (inherited) diseases. Women who have certain abnormal genes (known as BRCA1 and BRCA2) have an increased risk for developing ovarian cancer before age 70. If your mother or sister has had ovarian cancer, or you know that you have an abnormal BRCA gene, you may consider having your ovaries removed. You will not be able to become pregnant after having this surgery. And your risk for ovarian cancer will drop to nearly zero. Your breast cancer risk will also be lower. Talk to your doctor to decide if this choice is right for you.
  • Breast cancer. Hormones produced by the ovaries increase the risk of breast cancer. Oophorectomy may reduce the risk of breast or ovarian cancer in women who have the abnormal genes BRCA1 or BRCA2. Oophorectomy is sometimes recommended to treat breast cancer, because it eliminates the hormones produced by the ovaries.
  • Suspected disease. When a premenopausal woman is scheduled to have one ovary removed during the surgical removal of the uterus (hysterectomy) because disease is suspected, removal of both ovaries may be recommended if disease is found.
