Reduction rates in the RAL group were smaller than those in the SPA laparoscopy group for patients with mild endometriosis (early stage, AAGL stage I/II) (AMH reduction rates at 3 months postoperative: RAL vs. SPA laparoscopy, 23.58 ± 14.98% vs. 33.51 ± 19.98%; p = 0.04). This evidence concerns the gene AMH and endometriosis.
