Abstract
Repeated implantation failure is a major challenge in reproductive medicine and despite several methods that have been described for management, there is little consensus on which is the most effective. This study was conducted to evaluate the effectiveness of autologous platelet-rich plasma in improving the pregnancy rate in repeated implantation failure. Between 2016 and 2017, a total of 138 patients who failed to conceive after 3 or more embryo transfers with high quality embryos and candidate for frozen-thawed embryo transfer were assessed for eligibility to enter the study. Intrauterine infusion of 0.5 ml platelet-rich plasma (PRP) that contained platelets at 4-5 times higher concentration than peripheral blood was performed 48 h before blastocyst transfer. A control group received standard treatment. Ninety-seven patients completed the study procedure. There were no significant differences between the two groups in terms of age, body mass index and number of previous embryo transfers. The chemical pregnancy rate was higher in the PRP group than control group (53.06% versus 27.08%, respectively; p value: 0.009). Clinical pregnancy rate was higher in PRP group than control group (44.89% versus 16.66%, respectively; p value: 0.003). In conclusion, intrauterine platelet-rich plasma may be effective in the improvement of pregnancy outcome in repeated implantation failure.
