SummarySeveral autoimmune diseases are far more common in women than men. The reasons are unknown. Recent studies have shown that many autoimmune diseases which predominantly affect females are characterized by the production of autoantibodies against components of apoptotic cells. Furthermore, in experimental animals, defective clearance of apoptotic cells in a pro-oxidant inflammatory environment can trigger the production of these autoantibodies and related autoimmune disease. Endometriosis is characterized by defective clearance of apoptotic endometrial cells in a pro-oxidant inflammatory environment. It is proposed that this combination of abnormalities triggers autoantibody production in women affected by endometriosis. A proportion of these women will be genetically predisposed to develop overt autoimmune disease. As endometriosis affects at least 4% of the female population of reproductive age, this phenomenon will have a major effect on the gender prevalence of several related autoimmune syndromes. The hypothesis is supported by epidemiological studies which show a strong association between endometriosis and female-predominant autoimmune disorders.
