Endometriosis is a systemic, steroid-dependent, inflammatory disease characterized by the growth of endometrial-like tissue outside the uterus, affecting approximately 10 % of women of childbearing age. The etiology and pathophysiology of endometriosis is not completely understood to support effective treatment and prevention strategies. Despite the steroid dependency, little is known concerning the underlying metabolism of estrogen and other tightly related steroids. Moreover, shortening the long diagnostic delays is a major priority in endometriosis research.
