Objective. To evaluate the efficacy of Intraovarian autoplasmotherapy (platelet-rich plasma/PRP) in the activation of ovarian function in patients with diminished ovarian reserve and “poor” response in the in vitro fertilization (IVF) cycles, as well as its influence on the quality of life. Patients and methods. A total of 120 patients with diminished ovarian reserve and a history of IVF cycle failure who refused to use donor oocytes were included in the study. All patients underwent intraovarian PRP therapy based on the proprietary technology. The quality of life, the ovarian function, and the results of the embryo stage in the IVF cycle were monitored for 6 months. Results. The conducted study demonstrates a positive effect of intraovarian PRP therapy on the functional state of the ovaries and on the results of the embryo stage in IVF in the cohort of patients with diminished ovarian reserve and “poor” response in previous unsuccessful IVF cycles. The findings also indicate changes in the quality of life, an improvement in sexual function, and positive dynamics in the emotional state. Conclusion. Intraovarian PRP therapy allows patients with infertility and diminished ovarian reserve to avoid using donor oocytes and to obtain their own genetic material. This technology has a positive effect on the quality of life, having a certain anti-age effect in all groups of examined women, the duration of which has yet to be clarified. © 2021, Dynasty Publishing House.
