Background: A major challenge in reproductive medicine is repeated implantation failure (RIF). Possible benefits of platelet-rich plasma (PRP) for pregnancy outcomes are still uncertain, and more evidence is required to properly evaluate this. The current meta-analysis was therefore carried out to assess the impact of intrauterine PRP infusion on pregnancy outcomes in women with RIF. Methods: Various databases (Web of Science, PubMed, Cochrane Library, Embase) were screened for English-language papers that investigated the effect of PRP treatment on pregnancy outcomes in RIF women who underwent in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). This effect was analyzed in both frozen-thawed and fresh cycles. These studies involved randomized controlled trial (RCT) and quasi-experimental (non-randomized experimental) studies, but excluded case-control, case series, self-control, cross-sectional studies. The Newcastle-Ottawa Scale was employed to determine study quality. Risk ratios (RRs) were calculated for dichotomous outcome variables, and weighted mean difference (WMD) with 95% confidence interval (95% CI) for continuous outcome variables. These were performed under fixed- or random-effect models. Results: This meta-analysis evaluated 15 articles from the literature. Improved pregnancy outcomes were observed in RIF women who received PRP, including higher rates of implantation, clinical pregnancy and live birth compared to control patients. Conclusions: The results of this study indicate that PRP could be a useful treatment strategy for RIF patients and those with a thin endometrium. Additional large RCTs are required to identify the subpopulation of women who could derive the maximum benefit from PRP.
