Endometriosis Concepts

Endometriosis Concepts and Theories (PDF)

Endometriosis Concepts Page (HTML)

The Endometriosis Concepts and Theories page and files are focused on endometriosis history, concepts, theory and education beginning about 1,855 BC. This includes 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), transition from endometrium to endometriosis (1921), endometriosis different from endometrium "both in structure and in function" (1921), and retrograde menstruation (1921 & 1927). Ongoing research in endometriosis includes more than 27,300 articles in PubMed (NIH), 362,000 references at scholar.google.com, and 291,000 array- and sequence-based data in the GEO database (NIH). More than 400 references are included in the Endometriosis Concepts and Theories (PDF) summary. The summary also has introductions to the "tomato effect" and "reversal in evidence-based medicine."
