Can I get pregnant if I have endometriosis?

Yes. Many women with endometriosis get pregnant. But, you may find it harder to get pregnant. Researchers think endometriosis may affect as many as one in every two women with infertility.
No one knows exactly how endometriosis might cause infertility. Some possible reasons include:

Patches of endometriosis block off or change the shape of the pelvis and reproductive organs. This can make it harder for the sperm to find the egg.
The immune system, which normally helps defend the body against disease, attacks the embryo.
The endometrium (the layer of the uterine lining where implantation happens) does not develop as it should.
If you have endometriosis and are having trouble getting pregnant, talk to your doctor. He or she can recommend treatments, such as surgery to remove the endometrial growths.
