How endometriosis affects pregnancy
4-minute read
Endometriosis is a condition that affects about 1 in 9 women. Some women can have endometriosis and not know it, but for others it can cause symptoms such as pain.
About 1 in 3 women with endometriosis has trouble getting pregnant, but treatment can help. Once pregnant, most women with endometriosis will have an uncomplicated pregnancy.
What is endometriosis?
Endometriosis is a condition where tissue like the tissue that lines your uterus (womb) grows outside your uterus.
This tissue can grow around your:
- Ovaries
- Fallopian tubes (the tubes that allow eggs to travel from the ovaries to the uterus)
- Lining of your pelvis
This can cause scarring around these areas. It sometimes causes the pelvic tissues and organs to stick together.
The endometrial tissue can also grow and then break down and bleed when you have your periods. The tissue can get trapped in your body because it has no way to get out, and this can cause symptoms.
What are the symptoms of endometriosis?
Some of the symptoms of endometriosis include:
- tummy or pelvic pain
- painful, heavy, or irregular periods
- pain with passing wind, urine (wee) or stools (poo)
- pain during sex
- constipation
- diarrhoea
- bloating
- weeing more often
- tiredness
What causes endometriosis?
Nobody really knows, but it can run in families.
How can endometriosis affect fertility?
Many women with endometriosis fall pregnant naturally. But about one-third of women with endometriosis have trouble getting pregnant.
To get pregnant, an egg needs to be released from one of your ovaries. The egg then needs to travel through the fallopian tube. Most eggs are fertilised by sperm in one of the fallopian tubes. The fertilised egg then needs to attach to the lining of the uterus.
Endometriosis may prevent a pregnancy because the abnormal tissue may:
- block the ovary from releasing eggs
- block the fallopian tubes
- stop the fallopian tubes working properly
- stop a fertilised egg from attaching to the uterus
Endometriosis might also affect your fertility in other ways. It can damage the egg or sperm. Or it can cause inflammation which interferes with the delicate balance of hormones that women need to become pregnant.
Although it can be harder to get pregnant, most women with endometriosis are still able to have children.
How can endometriosis affect pregnancy?
Research looking at the effect of endometriosis on pregnancy hasn’t clearly shown any complications or risks during pregnancy. Some studies say that endometriosis does not have a big effect on pregnancy. Other studies say that endometriosis might increase the risk of a miscarriage or other complications.
Most women with endometriosis will have a normal pregnancy. Extra monitoring is usually not recommended, but this is something to discuss with your doctor.

During pregnancy, endometriosis can improve but it often comes back later and may cause problems becoming pregnant again.
Can I prevent endometriosis?
Endometriosis can't be prevented, but staying as healthy as you can might help with symptoms. For example: exercise, relaxation and ensuring you have enough sleep can help you manage pain.
Endometriosis can usually be treated with medications or surgery. See healthdirect for more information.
