Endometriosis Concepts

Endometriosis Concepts is focused on endometriosis history, concepts, theory and education. The Endometriosis Concepts and Theories summary begins about 1,855 BC and moves forward to Rokitansky's 1860 histology and Russell's 1899 recognition of non-visualized, intra-ovarian lesions of what Sampson would subsequently (1925) call endometriosis. Sampson also discussed venous dissemination (1918), epithelial metaplasia (1921), implantation from menstruating ovaries (1921), and retrograde menstruation (1927). Ongoing research in endometriosis includes more than 26,500 articles in PubMed (NIH), 365,000 references at scholar.google.com, and 291,000 array- and sequence-based data in the GEO database (NIH). More than 290 references are included in the Endometriosis Concepts and Theories summary. The summary also has introductions to the "tomato effect" and "reversal in evidence-based medicine."
