The College Referentials” prepared by a group of gynecology-obstetrics teachers under the aegis of CNGOF, CEGO and CNU, intended for second cycle medical students, include ITEM 41 exclusively concerning Endometriosis. This is a great step forward in the training of future doctors, called upon to confirm the diagnosis and offer care for women with endometriosis. The item is covered in Chapter 12, and was written by Prof. Horace Roman and Dr. Isabella Chanavaz-Lacheray.
