Intraovarian injection of autologous platelet-rich-plasma: myth or reality?

Introduction: The diminished ovarian reserve (DOR) relates to a condition in which the ovary experiences a decline in its typical reproductive capacity. Despite notable advancements in understanding the pathophysiology of reduced ovarian reserve in recent years, significant unresolved challenges remain, particularly concerning the optimal therapeutic approaches for this complex condition. The main aim of this study was to investigate the potential of platelet-rich plasma (PRP) in enhancing ovarian follicle numbers by assessing changes in ovarian reserve markers.

Evidence acquisition: A comprehensive literature search was conducted on the following databases: PubMed/MEDLINE, SCOPUS, The Cochrane Library, Science Direct and Web of Science. All the relevant studies published till October 2023 were screened. After removing duplicates, and full-text evaluation, 9 articles were eventually included in the present review.

Evidence synthesis: The pregnancy rate (PR) among patients with poor ovarian reserve (POR) ranged from 13% to 40%, indicating the potential effectiveness of PRP as a rejuvenating treatment. The live birth rate (LBR) ranged from 13% to 20%, comparable to or not lower than the LBR of a matched healthy population aged between 38 and 42 years. Furthermore, the data presented thus far support the notion that PRP may lead to an average clinical PR of 10% in women affected by premature ovarian insufficiency (POI) and perimenopause.

Conclusions: PRP can not be regarded as a gamete replacement therapy, but rather as an 'additional' therapeutic tool in the management of women with DOR or POR, as well as in peri-menopausal women. Additional qualitative studies are required to validate the existing evidence, as the literature currently lacks randomized controlled trials (RCTs) in this regard.
