Fecal Microbiota Transplantation for Obese Women With Polyendocrine Metabolic Ovarian Syndrome

Summary

This prospective, two-stage clinical trial aims to evaluate the safety, preliminary efficacy, and reproductive outcomes of oral Fecal Microbiota Transplantation (FMT) freeze-dried capsules in overweight and obese patients with Polyendocrine Metabolic Ovarian Syndrome (PMOS) undergoing Frozen-Thawed Embryo Transfer (FET).The study is implemented in two sequential phases: Phase Ⅰ (Pilot Exploration): A prospective, open-label, single-arm exploratory study in an initial evaluable cohort (n=11) to evaluate preliminary safety, dynamic gut microbiota colonization, endocrine/metabolic parameters, and pregnancy outcomes following FET. Phase Ⅱ (Confirmatory RCT): A planned multicenter, prospective, randomized controlled trial (RCT) designed to validate the clinical efficacy and underlying mechanisms of oral FMT capsules compared with control interventions, based on findings established in Phase Ⅰ.
