Staging of endometriosis
The American Society for Reproductive Medicine’s current classification of endometriosis in stages 1 to 4 is the most widely used and accepted staging system. The classification system uses point scores depending on location, extent, and depth of endometriosis implants; presence and severity of adhesions; and presence and size of ovarian endometriomas. However, the staging of endometriosis does not correlate with the presence of or severity of symptoms.
