Efficacy of intrauterine perfusion of granulocyte colony‐stimulating factor (G‐CSF) for Infertile women with thin endometrium: A systematic review and meta‐analysis

摘要

> This meta‐analysis aimed to explore the efficiency of intrauterine perfusion of granulocyte colony‐stimulating factor (G‐ CSF ) on infertile women with thin endometrium. Following PRISMA protocol, we conducted a comprehensive search of academic literatures on various databases including PubMed, EM base, and Cochrane Library. Studies published in English before July 1, 2016 were included for primary screening. Data on the thickness of endometrium, cycle cancelation rate,clinical pregnancy rate, and embryo implantation rate were extracted and analyzed, respectively. Eleven eligible studies involving 683 patients were included in this meta‐analysis. Compared with control group, G‐ CSF perfusion could significantly improve endometrial thickness (mean difference [ MD ]=1.79, 95% confidence interval ( CI ): 0.92‐2.67), clinical pregnancy rate (risk ratio [ RR ]=2.52, 95% CI : 1.39‐4.55), and embryo implantation rate ( RR =2.35, 95% CI : 1.20‐4.60), while it could decrease cycle cancelation rate ( RR =0.38, 95% CI : 0.25‐0.58). Funnel plots revealed that there was no evidence of publication bias. The current data indicate that intrauterine perfusion of G‐ CSF can improve endometrial thickness, clinical pregnancy rate, and embryo implantation rate, but decrease the cycle cancelation rate in women with thin endometrium.
