Local estrogen formation and its regulation in endometriosis
Abstract Background It has been well established that endometriosis is an estrogen‐dependent disease. Although the exact pathogenesis of the disease is still unclear, it is known to be characterized by estrogen‐dependent growth and maintenance of the ectopic endometrium and increased local estrogen...
