Having a hysterectomy? 5 side effects of having your ovaries removed

Here are some reasons why you may keep your ovaries if you’re having a hysterectomy.

About 6000 hysterectomies are performed in the U.S every year and about half or these are accompanied by removal of apparently normal ovaries. The reasoning behind this is that it reduces the occurrence of ovarian cancer, i.e. if your ovaries aren’t there, then they can’t become cancerous.

Ovarian cancer is not common – about 1 in 400 American women will develop ovarian cancer by the age of 50. The main problem with ovarian cancer is that it is usually detected in the late stages when treatment becomes virtually useless.

Unfortunately, removing the ovaries before the age of 65 also carries some major health risks. If you’re having a hysterectomy for a benign (non-cancerous) condition, here are 5 reasons to keep your ovaries:

  1. You will have less chance of developing ovarian cancer. Does that sound confusing? Let me explain. When you have a hysterectomy, the surgeon looks at the ovaries to make sure that they’re healthy before the abdomen is closed up. Any abnormal looking ovaries are usually removed at this point. A more likely explanation according to some studies that have been done suggests that:
    • removal of the uterus closes the route through which cancer-causing agents like talc, uterine tissue and the human papilloma virus would have reached the ovaries,
    • destruction of some tissues of the reproductive system cause release of substances which in turn cause the production of antibodies which protect you from developing ovarian cancer.

    This reduced risk of developing ovarian cancer lasts for 10-20 years after the hysterectomy.

  2. After menopause, the ovaries continue producing the hormones androstenedione and testosterone until the age of 80. These hormones are converted to estrone, the main form of estrogen found in the body after menopause. Removal of the ovaries even after menopause can cause sudden onset or worsening of menopause symptoms like hot flashes, sleep disturbances and depression.
  3. You’ll be less likely to have a hip fracture. Estrogens and androgens slow down the rate at which bone is broken down in the body. Removing the postmenopausal ovary removes a major source of androgens which are converted to estrogen. One study has shown that women who had their ovaries removed after menopause had a 54% higher risk of having a fracture due to osteoporosis than postmenopausal women who still had their ovaries.
  4. You will have less chance of developing heart disease. The absence of the sex hormones that are produced after menopause further increase your risk of developing heart disease. This could be bad news especially if you have other risk factors for heart disease. Recent research has shown that women who have their ovaries removed have a much higher risk of developing heart disease.
    Two groups of women (one group had their ovaries removed and the others kept theirs) were studied and the results showed that the women who had their ovaries removed:
    • had a higher chance of dying (12% increase)
    • had a higher risk of developing heart disease (17% increase)
    • had a higher chance of developing lung cancer (26% increase)

    However, they did not develop ovarian cancer and were less likely to get breast cancer.

    In the US about 14,700 women die from ovarian cancer each year. While this is a painful experience for the woman and her family, this is much less than over 400,000 deaths in women from from heart disease and stroke combined.

  5. Medication may not be the solution.It has been argued that estrogen replacement therapy and other forms of medication can help with some of these conditions like menopausal symptoms and osteoporosis after the ovaries have been removed. These therapies have their own risks and some women go off the medication because of distressing side effects.

With women living longer now (average of 78 years), quality of life becomes very important in any decision you take about your health. I haven’t written this to scare you into keeping your ovaries. I think it’s important to have a balanced view so that you can make informed decisions. Do some reading, talk to your doctor, ask him/her questions and expect answers in simple language you can understand. At the end of all this, make the decision that best suits your personal circumstances.

  1. I really need advice, can I please have a consultation with you? I would be happy to pay a fee. I am trying to make a decision to keep an ovary or not during a hysterectomy. I am age 41, my Mom currently has Ovarian cancer, but the genetic tests show she does NOT carry the gene to pass it on. I have endometreosis .
    Thanks you for your time.

  2. I have been concerned that I may have ovarian cancer. I have an onocologist that has been monitering me due to enlarged lymph nodes with questional biopsy results. I had a partial hysterectomy 29 yrs ago and was told the ovaries were cystic but left for hormone production. I was also told that the ovaries would need to be removed in the future and gave them 5 yrs. I never had them removed and do have symptoms of ovarian cancer now. My abdominal area has swelled up that I look pregnannt. I do not have weight gain anywhere else. I had the ca-125 blood test last year but it was ok then. I am also in final stage of Myasthenia Gravis and fighting cellulitis in my legs from build up of lymph fluid and lasix ddoes nothing for me. My next visit I plan to bring up the subject of ovarian cancer with my onocologist. Wish me luck…………

  3. I had a partial hysterectomy at the age of 28. I still have one ovary. I had what the doctor called “precancerous cells”. But, now I have alot of strange things going on such as breast tenderness and lack of sex drive. I still have one ovary so I’m not sure if it’s premenopause. I don’t have night sweats or mood swings either. Should I worry about cancer in the other ovary? The doctor said it may need to be removed in the future. This was two years ago.

  4. Please help, what about removal of both overies, only the overies, when only one has a cyst on it?
    It is supposed to be a clear liquid cyst… which has grown to be about the size of a tennis ball.

  5. Ovarian cancer is definitely not the most common cancer in women. However, every woman that develops cancer of the ovaries is more than just a statistic. That said, it’s a good idea to have a transvaginal ultrasound scan every year. Other screening methods are not too well developed right now. Don’t panic, just be vigilant
