cases of amenorrhea under hormonal treatment, severe chronic pelvic pain (average VAS ≥ 6\u002F10 over the last 3 months), described as cramp-like, localized in the pelvic region, and similar to the initial dysmenorrhea pain.\n* Having failed optimal first-line medical treatment combining hormonal therapy and appropriate analgesics (Level I and II analgesics, and NSAIDs),\n* Having undergone a pelvic MRI within 1 year prior to the randomization visit that shows no evidence of deep infiltrating endometriosis or endometrioma, following systematic review by radiologists from the expert center
