Answer

Answer

Staging of endometriosis depends on the degree and complications of endometrial implants. The American Society for Reproductive Medicine  (ASRM) classification of endometriosis categorizes endometrial implants, such as location and the depth of penetration, as well as the degree of cul-de-sac obliteration and adhesions. The findings on laparoscopy can be used to classify patients into 4 classes, from mild (stage I) to severe (stage IV). [12]  In 2017, the World Endometriosis Society consensus statement on the classification of endometriosis proposed a classification toolbox that includes the revised American Society for Reproductive Medicine and, where appropriate, the Enzian and Endometriosis Fertility Index staging systems.
