AMH and endometriosis: The standardized mean difference was obtained in examining unilateral laparoscopic surgery for endometriosis (before intervention 2.8 ± 0.11 and after 3 months 2.05 ± 0.13; and before intervention 3.1 ± 0.46 and after 6 months 2.08 ± 0.31), and in examining bilateral laparoscopic surgery for endometriosis (before intervention 2.08 ± 0.08 and after 3 months 1.1 ± 0.1; before intervention 2.9 ± 0.23 and after 6 months 1.4 ± 0.19), which indicates unilateral and bilateral laparoscopic surgery for endometriosis is effective on AMH level.
