There have been no reports on the effect of G-CSF on the recurrence of IUAs, endometrial regrowth or pregnancy results in specific populations with AS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>STUDY DESIGN, SIZE, DURATION<\/jats:title>\n                    <jats:p>This two-center prospective double-blind randomized controlled trial ran between April 2016 and August 2021. In it, 245 patients with moderate to severe AS were randomized to G-CSF and control groups at a 1:1 ratio; 229 women were included in the adhesion recurrence analysis; and 164 patients were analyzed for pregnancy outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>PARTICIPANTS\/MATERIALS, SETTING, METHODS<\/jats:title>\n                    <jats:p>All eligible patients received the first hysteroscopic adhesion separation and balloon placement procedure. Patients who met our inclusion and exclusion criteria were randomized after surgery. These patients returned for balloon removal and underwent intrauterine perfusion with 300 \u00b5g (1.8 ml) G-CSF or 1.8 ml normal saline according to randomization at 7 days after surgery. A second-look hysteroscopy was carried out 1\u20132 months later. The primary outcome was the rate of formation of new adhesions at the second hysteroscopy. The secondary outcomes included endometrial thickness in the periovulatory period after surgery, as well as the clinical pregnancy and live birth rates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>MAIN RESULTS AND THE ROLE OF CHANCE<\/jats:title>\n                    <jats:p>Age, menstrual cycle characteristics, pregnancy history and IUA score before surgery were similar between groups. There were no statistically significant differences in the adhesion reformation rate or median adhesion score reduction. However, G-CSF perfusion significantly improved endometrial thickness (7.91 \u00b1 2.12 mm vs 7.22 \u00b1 2.04 mm; P = 0.019, 95% CI for difference: \u20131.26 to \u20130.12), as well as cumulative pregnancy and live birth rate over time (P = 0.017 and P = 0.042). Furthermore, multivariate logistic regression analysis showed that postoperative endometrial thickness was an independent prognostic factor for pregnancy and live birth rates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LIMITATIONS, REASONS FOR CAUTION<\/jats:title>\n                    <jats:p>These results cannot be extended to older patients or those without AS, as our subjects had moderate or severe AS and were aged &amp;lt;40 years.
