Hysterectomy and Oophorectomy: Should I Use Estrogen Therapy (ET)?

Get the facts

Your options

  • Use estrogen therapy (ET) after hysterectomy and oophorectomy.
  • Don't use ET. Try other treatment for menopause symptoms and to prevent osteoporosis.

Key points to remember

  • Until menopause, the ovaries make most of your body's estrogen. When your ovaries are removed (oophorectomy) during a hysterectomy, your estrogen levels drop. Estrogen therapy (ET) replaces some or all of the estrogen that your ovaries would be making until menopause.
  • Without estrogen, you are at risk for weak bones later in life, which can lead to osteoporosis. ET lowers your risk by slowing bone thinning and increasing bone thickness.footnote 1
  • If you are in your 20s, 30s, or 40s, you may want to use ET to avoid early menopause after oophorectomy. But if you have already gone through menopause, you probably don't need ET after your ovaries have been removed.
  • Early menopause can cause hot flashes and other symptoms. ET lowers the number of hot flashes you have, and it makes them less severe when you do have them. ET also helps with other early menopause symptoms, such as vaginal dryness and sleep problems.
  • ET does have risks, including a slight risk of stroke and blood clots. But for most women in their 20s, 30s, or 40s who have had their ovaries removed, the benefits of ET are stronger than these risks.
  • Instead of ET, you might try other prescription medicines to help with early menopause symptoms and to prevent osteoporosis. And you may be able to prevent bone thinning if you take vitamin D supplements, eat foods that are rich in calcium, and do weight-bearing exercises.
FAQs

What are hysterectomy and oophorectomy?

A hysterectomy is surgery to remove the uterus. Most of the time, a hysterectomy is done to treat a problem with the uterus, such as heavy menstrual bleeding, uterine fibroids, or endometriosis.

An oophorectomy is surgery to remove the ovaries. Oophorectomy (say "oh-uh-fuh-REK-tuh-mee") may be done because of a growth on one or both ovaries, or to treat severe endometriosis, or breast cancer. It may also be done to lower the risk of ovarian cancer.

About half of American women who have a hysterectomy also have their ovaries removed during the same surgery.footnote 2

What is estrogen therapy (ET)?

ET is the use of man-made estrogen to replace the natural estrogen made by your ovaries. ET is available as a pill, a skin patch, a vaginal ring, or a skin cream or gel.

Until menopause (around age 50), the ovaries make most of your body's estrogen. When your ovaries are removed, your estrogen levels suddenly drop. This causes early menopause. It can also increase your risk of osteoporosis and bone fractures, because estrogen helps your bones stay strong.

ET keeps estrogen levels up, which protects against bone thinning and helps prevent menopause symptoms.

If you are in your 20s, 30s, or 40s, you may want to use ET to avoid sudden early menopause after having your ovaries removed. But if you have already gone through menopause, you probably don't need ET after an oophorectomy.

What are the benefits of ET after hysterectomy and oophorectomy?

Estrogen therapy:

  • Lowers your risk of osteoporosis. ET slows bone thinning and helps increase bone thickness.
  • Reduces the number of hot flashes that you have, and it makes them less severe when you do have them.
  • Prevents vaginal dryness and soreness caused by low estrogen.
  • Slows the loss of skin collagen. Collagen puts the stretch in skin and muscle.
  • Reduces the risk of dental problems, such as gum disease and tooth loss.
  • May help sleep problems and moodiness linked to hormone changes.footnote 3
  • May reduce the risk of colon cancer.footnote 4

What are the risks of ET?

Estrogen therapy may increase the risk of health problems in a small number of women. This increase in risk depends on your age, your personal risk, and when ET is started. Talk with your doctor about these risks. Using ET may increase your risk of:footnote 3

  • Stroke.
  • Blood clots.
  • Gallstones.

You should not take ET if:

  • You have unexplained vaginal bleeding.
  • You have liver disease or other problems with your liver.
  • You have breast cancer, ovarian cancer, uterine cancer, or blood clots or have had a stroke.

If a close family relative has had breast cancer, ET may not be right for you. Talk with your doctor about the risks and benefits.

What other treatment might you try instead of ET?

Instead of ET, you might try other prescription medicines for menopause symptoms.

  • Antidepressant medicines can lower the number of hot flashes you have. And they can make hot flashes less severe when you do have them. Some women have side effects such as headaches, an upset stomach, and problems sleeping. It's not clear how safe this medicine is if it's taken for a long time.
  • Clonidine, a blood pressure medicine, may relieve hot flashes for some women. But studies have not shown that clonidine makes hot flashes less severe or less frequent. Some women have side effects related to low blood pressure.
  • Gabapentin (Neurontin), an antiseizure medicine, may lower the number of hot flashes each day and the intensity of hot flashes. Possible side effects include sleepiness, dizziness, and swelling.

You might also try black cohosh, which is a medicinal root, or dietary soy to manage hot flashes.

To reduce your risk of osteoporosis, eat foods that are rich in calcium, and take vitamin D supplements.

You might also try other medicines to prevent bone thinning.

Why might your doctor recommend ET after hysterectomy and oophorectomy?

Your doctor might recommend ET after hysterectomy and oophorectomy if:

  • You are in your 20s, 30s, or 40s.
  • You need treatment to prevent early bone thinning and osteoporosis.

Personal stories about deciding to use estrogen therapy

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.

Since having my uterus and ovaries removed, I've been taking ET. This makes a lot of sense to me, because my ovaries would be producing estrogen until I hit menopause. When I'm the age I'd expect to be menopausal, around age 50, I expect I'll stop or reduce the estrogen I'm taking. That'll depend on what experts recommend by then.

Josie, age 35

I started taking ET after a radical hysterectomy and spent a number of months struggling with moodiness and feeling depressed. It was probably because of the big changes in hormones after my ovaries were removed. I worked closely with my doctor to make adjustments to my hormone replacement. She replaced the oral estrogen with a patch. Now, I've been doing well for more than 5 years.

Carla, age 28

I took ET for many years after having my uterus and ovaries removed in my 30s. I figured I'd take it for the rest of my life, since that is what my doctor said I should do. But I recently heard about the latest research on the risks of taking hormones, and my doctor and I decided that I really don't need to take ET. If I had risks for osteoporosis and needed the estrogen to keep my bones strong, I'd take a low dose, but I don't have any worries right now about weak bones.

Anna, age 64

I had a hysterectomy and oophorectomy in my early 40s, but I didn't take ET because my family has a history of breast cancer that's linked to estrogen. The sudden menopause after having my ovaries removed was pretty bad, but I took really good care of myself with exercise, a good diet, and a lot of tricks for handling hot flashes, and I got through it after a while.

Estella, age 58
