Advances in assisted reproductive technology (ART) have led to a significant increase in the number of pregnancies, but despite great progress in embryo selection and quality improvement, many patients still experience repeated implantation failures. Most studies use autologous platelet-rich plasma (PRP) in clinical cases of patients with thin endometrium, repeated implantation failure, chronic endometritis, and Asherman’s syndrome, since, unfortunately, there is still no effective remedy for these conditions. The lack of evidence-based treatments indicates the urgency of the problem. Recently, more and more data have appeared confirming the positive role of PRP in the treatment of the endometrium. A search was made in the PubMed, Cochrane library databases. As a result of using combinations of keywords: (PRP) AND (reproductive); 552 articles were identified. 47 papers were selected and their data included in the literature review. The article presents current data on the clinical use of platelet-rich plasma in the field of reproductive medicine. Given the complexity of platelet signaling and activation, the exact details of initiation of the full spectrum of platelet physiological effects remain unclear. The review describes the identified effects and possible mechanisms of action of plasma on ovarian and endometrial tissue. Available evidence suggests that PRP may be an effective alternative for women with poor ovarian reserve and may improve pregnancy outcomes in women with repeated implantation failure, suggesting a promising role for assisted reproductive technologies in these patients.
