Pathogenesis and pathophysiology of endometriosis

Richard O Burney et al. Fertil Steril. 2012 Sep.

Abstract

Originally described over three hundred years ago, endometriosis is classically defined by the presence of endometrial glands and stroma in extrauterine locations. Endometriosis is an inflammatory, estrogen-dependent condition associated with pelvic pain and infertility. This work reviews the disease process from theories regarding origin to the molecular basis for disease sequelae. A thorough understanding of the histopathogenesis and pathophysiology of endometriosis is essential to the development of novel diagnostic and treatment approaches for this debilitating condition.
