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).
