Efficacy and Safety of Platelet-Rich Plasma Injections for the Treatment of Female Sexual Dysfunction and Stress Urinary Incontinence: A Systematic Review
Bibliographic record
Abstract
Introduction: There is no clear evidence in the literature that platelet-rich plasma (PRP) injections improve female sexual dysfunction (FSD) and female stress urinary incontinence (SUI). Objectives: A systematic review was performed to study the efficacy and safety of PRP injections in women with the above pathologies, as well as to explore the optimal dosing, frequency and area of injections, and duration of treatment. Methods: A systematic search on PubMed, Embase and the Cochrane Library database was performed, as well as sources of grey literature from the date of database or source creation to January 2023. After title/abstract and full-text screening, clinical studies on humans evaluating the efficacy of PRP in gynecological disorders using standardized tools were included. Risk of bias was undertaken with RoB-2 for randomized-controlled trials (RCT) and the Newcastle-Ottawa Scale (NOS) for observational studies. Results: Four prospective and one retrospective study explored FSD, while six prospective and one RCT evaluated female SUI. A total of 327 women with a mean age of 51 ± 12 years were included. For FSD, PRP significantly improved the Female Sexual Function Index (FSFI), the Vaginal Health Index (VHI) and the Female Sexual Distress score (FSDS). For SUI, PRP led to a significant improvement in the International Consultation on Incontinence Questionnaire—Short Form (ICIQ-SF) and the Urogenital Distress Inventory (UDI-6). The identified RCT reported a significantly higher mean score of ICIQ-SF (p < 0.05) and UDI-6 (p < 0.01) in the midurethral sling group compared to the PRP injections group. Regarding the risk of bias, the RCT was characterized by high risk, whereas the observational studies were of moderate risk. The protocol for PRP injections for FSD is the injection of 2 mL of PRP into the distal anterior vaginal wall once a month for 3 months. For female SUI, 5–6 mL of PRP should be injected into the periurethral area once a month for 3 months. Conclusions: Despite the promising initial results of PRP injections, the level of current evidence is low due to methodological issues in the available studies. It becomes clear that there is an emerging need for high-quality research examining PRP injections for the treatment of FSD and female SUI.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
