#144 : Randomized Controlled Trial Evaluating Efficacy of Autologous Platelet-Rich Plasma Therapy for Patients with Recurrent Implantation Failure in Frozen-Thawed Embryo Transfer After PGT-A

Background and Aims: Despite keen development of ART, recurrent implantation failure (RIF) remains a challenging dilemma for fertility specialists. As it contains significant growth factors involved in delicate process of implantation, platelet–rich plasma (PRP) therapy should promote endometrial receptivity and improve ART. Objective: To evaluate if the intrauterine perfusion with autologous PRP enhances frozen-thawed embryo transfer effectiveness in patients with RIF after PGT-A. Methods: Study type: Interventional. Design: randomized controlled study Intervention Model: Parallel Assignment Masking: open label After obtaining institutional review board approval, 232 women aged 28-42 years were involved. Matching criteria: RIF, normal karyotype, absence of uterine factors of infertility, availability of euploid embryos after PGT-A (NGS). 2 groups of patients: study group (N = 118): single IP with 2.0 ml of autologous PRP on day 10-11 of menstrual cycle; Control group: no therapy (N = 114). Endometrium preparation was carried out according to standardized protocol. Primary outcome measure was clinical pregnancy rate. Secondary outcome measures were pregnancy loss rate, endometrial thickness and adverse event. Results: The clinical pregnancy rate was higher in the study group (63.55% vs 38.59%) ([Formula: see text]2=14.462, OR=2.775, 95% CI 1.630 - 4.722, p0,05). No adverse event was noted. Conclusions : –The PRP intrauterine perfusion should be considered perspective, safe and cost-effective therapy method for patients with RIF. –PRP does not influence on pregnancy loss rate –Meta-analysis is required.
