Endometriosis and pregnancy

Learn about endometriosis and pregnancy including information on getting pregnant when you have the condition.

Endometriosis is a long-term condition affecting women of childbearing age. Endometriosis can affect fertility but the majority of women with the condition are still able to get pregnant.

This article covers the symptoms of endometriosis, treatment, effects on fertility, and implications for pregnancy.

What is endometriosis?

In endometriosis, small pieces of the inner lining of the uterus (womb) are found elsewhere in the body. This lining is called the endometrium. The pieces of tissue may become attached to other organs, such as the bladder, bowel or ovaries.

Endometriosis affects around two million women in the UK. Most of them are diagnosed between the ages of 25 and 40. It is likely, though it has not been proved, that endometriosis is caused by a combination of genetic, immune system and hormonal factors. The condition is long-term and has no cure. However, symptoms can be managed and fertility improved with pain medication, hormone treatment or surgery.

Symptoms of endometriosis

Endometriosis commonly causes pain in the lower abdomen (tummy), pelvis or lower back. Pelvic pain often, but not always, coincides with the menstrual cycle, so you may have worse pain during your period.

Some women have few, or no, symptoms, but others experience severe pain that disrupts their lives.

Treatment of endometriosis

Unfortunately, there is no known cure for endometriosis. However, the symptoms can often be managed with painkillers or hormone treatment, which help prevent the condition from interfering with your daily life.

Surgery to remove patches of endometriosis tissue can sometimes be used to improve symptoms and fertility too. Treatment may not be necessary if symptoms are mild.

Endometriosis, fertility and getting pregnant

One of the main complications of endometriosis is difficulty getting pregnant (this may affect may affect about 30- 40% of the women who have endometriosis) or not being able to get pregnant (infertility). Fertility problems occur because the tissue from the endometrium may be found in the ovaries or fallopian tube and stops these organs working properly.

Although surgery cannot guarantee that you will be able to get pregnant, there is good evidence that removing visible areas of endometriosis with a laser or an electric current during keyhole (laparoscopic) surgery can improve your chances of having a successful pregnancy. 

Endometriosis and relief from symptoms during pregnancy

The majority of women with endometriosis who wish to get pregnant are able to do so, either with or without some medical treatment for the endometriosis. When you are pregnant, the painful symptoms of endometriosis may reduce or disappear. However this effect is not likely to last after pregnancy and breastfeeding have finished.
