Autologous platelet rich plasma (PRP) intraovarian infusion may improve ovarian response to controlled ovarian stimulation as well as the hormonal profile of poor ovarian response infertile women subjected to intracytoplasmic sperm injection (ICSI) treatment.
Despite recent advances in reproductive medicine, poor ovarian response (POR) management is still considered to be very challenging. Commonly, POR patients present with reduced ovarian reserve and poor ovarian stimulation performance. The POR cycles are characterized by a very limited number of retrieved oocytes, subsequently leading to poor embryo formation and thus to high cycle cancelation rate. Despite the fact that POR constitutes a multifactorial condition, it is well demonstrated that advanced maternal age (AMA) is the most significant contributor of POR. As maternal age increases, reduction of neo-angiogenesis in ovaries is observed, leading to accelerated follicular loss. Considering that PRP contains several growth factors such as vascular endothelial growth factor (VEGF) and cytokines, it has been proposed that intraovarian infusion of autologous PRP could restore the ovarian niche microenvironment, increasing ovarian response to external gonadotropin stimulation. However, limited data are available with regards to PRP efficiency in POR patients, which are mainly originating from pilot or small cohort studies. This interventional non-randomised open-label study aims to investigate the effect of autologous PRP intraovarian infusion on improving POR patient performance by studying a large and well-controlled POR population.

Preparation of PRP will be performed immediately following blood sample collection. Blood samples will be collected from the median antebrachial vein. PRP will be prepared according to the manufacturer's instructions employing a Regen Autologous Cellular Regeneration (ACR®-C) Kit (Regen Laboratory, Le Mont-sur-Lausanne, Switzerland). Approximately 60 mL of the patient's peripheral blood will be required in order to yield the required volume of PRP. The goal concentration of platelets in PRP is approximately 1.000.000 platelets/µL. The technique of PRP intraovarian infusion resembles the transvaginal paracentesis performed during the oocyte pick-up procedure. Briefly, both ovaries are visualized via transvaginal ultrasound monitoring, and they are intramedullary injected on multiple sites using a 17-gauge single lumen needle, with the patient under inhaled minimal sedation.
