Study selection
We searched the databases PubMed/Medline, Cochrane Library, Web of Science/Knowledge, and Embase. We searched associated terms on the PubMed MeSH database for “ovarian cysts,” “laparoscopy,” “electrocoagulation,” and “anti-Müllerian hormone,” or “antral follicle count.” Then, we searched for articles in the mentioned databases to find those published before October 2022. We also hand-searched the bibliographies of included studies and previous systematic reviews to identify further relevant trials. We included RCTs that evaluate the impact of bipolar coagulation on postoperative ovarian reserve in comparison to nonthermal hemostasis methods during laparoscopic surgery. The included studies measured preoperative and postoperative AMH or AFC in premenopausal women who underwent laparoscopic cystectomy. The two authors (LHH and YHL) independently screened the titles and abstracts of the studies under consideration for inclusion and eliminated the ineligible ones. The selection process did not involve the use of any automation tool. The eligible studies’ entire texts were examined to determine their suitability for inclusion. Any disagreements concerning the inclusion of a study were resolved by discussing the matter or consulting with a third author (THL).
