Endometriosis is a chronic gynecological disease in which tissue that resembles that in the lining of the uterus (the endometrium) grows outside the uterus where it does not belong. This can lead to the development of lesions, pelvic pain, heavy or irregular periods, and other symptoms. Endometriosis affects an estimated one in 10 women in the United States, and can develop in any girl or woman after the onset of menstruation, although it is most commonly diagnosed in women in their 30s and 40s.

It is common for individuals living with endometriosis to face challenges along their path to diagnosis, including physical, emotional, and financial burdens. Endometriosis also has a significant influence on infertility in women. Moreover, stigma surrounding pain and menstrual issues in women have limited scientific innovation and public awareness for endometriosis and related gynecologic health conditions.

Endometriosis is part of the SWHR Gynecologic Health Network, which engages the following focus areas: Endometriosis, Polycystic Ovary Syndrome, Urology, and Uterine Fibroids.
