The ASRM revised classification (1996) for endometriosis is based on laparoscopic findings. Stage IV (severe) endometriosis is defined by a total score of:

• A >40 points ✓
• B 1–5 points
• C 6–15 points
• D 16–40 points

Explanation

The ASRM 1996 revised classification scores peritoneal and ovarian endometriosis lesions plus adhesion extent and density: Stage I (minimal) = 1–5, Stage II (mild) = 6–15, Stage III (moderate) = 16–40, Stage IV (severe) = >40 points. Severity correlates poorly with symptom intensity but has some predictive value for fertility prognosis. This classification is primarily useful for surgical staging and research standardization.
