Comparing the Impact of Autologous Platelet-rich Plasma and Granulocyte Colony Stimulating Factor on Pregnancy Outcome in Patients with Repeated Implantation Failure

Despite the advancements in assisted reproductive technologies, repeated implantation failure (RIF) still remains a challenging problem for patients and clinicians. The aim of the present study was to compare the impact of intrauterine infusion of autologous platelet-rich plasma (PRP) and systemic administration of granulocyte colony stimulating factor (GCSF) on pregnancy outcome in patients with repeated implantation failure. The present retrospective cohort study included 123 patients with history of more than two repeated failed embryo transfers. Cycles were divided into two groups of intrauterine infusion of PRP (n=67) and systemic administration of GCSF (n=56). Pregnancy outcome was compared between two groups. The p-value less than 0.05 was considered statistically significant. The clinical pregnancy rate was significantly higher in PRP group than GCSF group (40.3% versus 21.4%, p=0.025). The crud and adjusted odds ratios (95% confidence interval (CI)) were 2.5 and 2.6 (p=0.025, CI: 1.11-5.53 and p=0.03, CI: 1.10-6.15), respectively. It seems that intrauterine infusion of PRP can positively affect pregnancy outcome in RIF patients in comparison with systemic administration of GCSF and more studies need to be designed to conclude the effectiveness of this method.
