Study design:

Non randomized control 

研究目的:

本项目拟综合运用高通量测序、代谢组学及分子生物学技术,通过动物实验探究卷曲乳杆菌促进 IVF 临床妊娠的分子调控机制;同时,扩大临床入组人数,进一步验证卷曲乳杆菌干预 CE 对提高不孕症患者 IVF 临床妊娠率的作用,为临床应用提供循证支持。  

Objectives of Study:

This project aims to employ a comprehensive approach integrating high-throughput sequencing, metabolomics and molecular biology techniques to investigate, through animal studies, the molecular regulatory mechanisms by which Lactobacillus curvatus promotes clinical pregnancy in IVF. Concurrently, by expanding the clinical cohort size, it will further validate the efficacy of Lactobacillus curvatus intervention in improving clinical pregnancy rates in infertile patients undergoing IVF, thereby providing evidence-based support for clinical application.
