Endometriosis Sample Collection Study

The purpose of this study is to learn more about the lining of the uterus, called the endometrium, by taking samples of endometrial tissue. Samples are taken by a common procedure called an endometrial biopsy. We will look at markers of inflammation and altered energy metabolism in people with and without endometriosis in order to better understand the disease and identify new and better ways to treat endometriosis.
