Endometriosis is another common reproductive condition that affects more than one in 10 women in the United States. This occurs when tissue found in the uterus grows in other parts of the body, such as the fallopian tubes or ovaries. Even mild endometriosis can reduce fertility, while severe endometriosis can distort the pelvic anatomy of a woman.
It is still possible for a woman with endometriosis to become pregnant, and, once pregnant, the pregnancy is expected to be no different from that of a woman without endometriosis.
