Background: Platelet-rich plasma (PRP) therapy has been shown to enhance tissue regeneration by expressing several
cytokines and growth factors (GFs). This study investigated the effect of intrauterine infusion of PRP as a noninvasive
autologous GF on pregnancy outcomes in women with repeated implantation failure.
Materials and Methods: This randomized clinical trial was conducted to compare the pregnancy rates between two
groups of women who were candidates for the frozen-thawed embryo transfer with a history of two or more implantation
failures. The PRP group (n=33) was treated with hormone replacement therapy+0.5 cc to 1 cc PRP infused
into the uterine cavity two days before the embryo transfer. The control group (n=33) was only treated with hormone
replacement therapy. The endometrial preparation process was done similarly in both groups. The chemical, clinical,
and ongoing pregnancy, and implantation rates were compared between the two groups.
Results: Our results showed that the chemical pregnancy rate was not statistically higher in the PRP group in comparison
with the control group (36.4 vs. 24.2%). In addition, the clinical pregnancy, ongoing pregnancy, and implantation
rates were higher in the PRP group than the control group; however, the difference between the two groups was not
statistically significant.
Conclusion: Administration of intrauterine PRP before embryo transfer in women with repeated implantation failure
(RIF) does not affect assisted reproductive technology (ART) outcomes (registration number: IRCT2016090728950N3).
