Regarding "AAGL 2021 Endometriosis Classification: An Anatomy-based Surgical Complexity Score" Reply

Many classifications proposed for this disease over the last decades. While most classification systems have been tailored to measure particular outcomes, all have limitations. In this study, we validated this new system's ability to predict pain and infertility symptoms using a prospective, multi-center study involving over 1,200 cases and compared it to the ASRM classification for endometriosis. Future improvements are necessary to the proposed classification and the development of a preoperative classification by imaging are the next steps.
