NIH Websites Are Changing

Beginning in late July, NIH will start introducing a new website experience designed to make it easier to find health information, research, funding opportunities, and other resources. During the transition, you may notice changes to navigation, page layouts, and where some information is located.

Endometriosis

Endometriosis is a disease in which tissue similar to the lining of the uterus grows in other places in the body. It is one of the most common gynecological diseases, and its primary symptoms include pain and infertility.

NICHD conducts and supports research to improve understanding of the mechanisms, diagnosis, and treatments of endometriosis.
