The primary outcome was the mean number of metaphase II (MII) oocytes retrieved in each group. Secondary outcomes included the mean number of embryos formed and serum β-human chorionic gonadotropin (β-hCG) positive rate in each group.  \nResults: A total of 3090 women were included, out of which 1210 and 1880 received Folisurge and Gonal-f, respectively. The baseline demographics were comparable in the two groups. The mean antral follicle count (AFC) was significantly higher in the Folisurge vs. the Gonal-f group (23 .8 vs. 20.6, p \u003C 0 .001) . Also, the mean (SD) number of oocytes retrieved was significantly higher in the Folisurge vs. the Gonal-f group (18 .1 (9 .4) vs.  \n15.5 (8 .3), p \u003C 0 .001) . The mean (SD) number of MII oocytes retrieved with Folisurge was significantly higher than Gonal-f (13 (7.5) vs. 10.9 (6 .6), p \u003C 0 .001) . Also, the mean (SD) number of embryos formed was also higher in the Folisurge vs. the Gonal-f group (4 .9 (4 . 1) vs. 4.7 (4 . 1), p = 0 .022) . The serum β-hCG positive rate was similar between the two groups (75 .5% vs. 76.2%, p = 0 .667) . No major safety concerns were observed in the study.  \nConclusion: Folisurge was comparable to Gonal-f in terms of serum β-hCG positive rate. The higher yield ofoocytes and embryos in the Folisurge group should be interpreted in the context of its higher baseline AFC, which may have influenced these results. No major safety concerns were observed.  \nCategories: Other, Obstetrics/Gynecology, Healthcare Technology  \nKeywords: antral follicle count (a","cbCaiphXR2zvtEnt","https://ap.wps.com/l/cbCaiphXR2zvtEnt","pdf",1064637,11,"English","# Abstract\n## Objective\n## Methods\n## Results\n## Conclusion\n# Introduction","[{\"question\":\"What was the main objective of the study?\",\"answer\":\"To compare the efficacy and safety of Folisurge versus Gonal-f in assisted reproductive technology patients.\"},{\"question\":\"How was the study designed and who was included?\",\"answer\":\"It was a non-interventional, investigator-initiated, real-world retrospective study including women aged 21–40 with BMI 17–34.9 and serum AMH \\u003e1.2 ng/mL receiving Folisurge or Gonal-f during controlled ovarian stimulation.\"},{\"question\":\"What outcomes were used to evaluate efficacy and what were the safety findings?\",\"answer\":\"Primary efficacy was mean metaphase II (MII) oocytes retrieved; secondary outcomes included embryos formed and serum β-hCG positive rate.
