Method of Administering a Therapeutic

The present invention relates to novel genetic markers associated with endometriosis and risk of developing endometriosis, and methods and materials for determining whether a human subject has endometriosis or is at risk of developing endometriosis and the use of such risk information in selectively administering a hormonal treatment such as a combined estrogen/progestin therapeutic which specifically includes an oral contraceptive that at least partially prevents or compensates for an endometriosis related symptom.
