PRP for Sexual Function

29. oktober 2026 opdateret af: Charles Ascher-Walsh, Icahn School of Medicine at Mount Sinai

Vaginal Injection of Platelet Rich Plasma for Sexual Dysfunction: A Randomized Control Trial

This randomized, single-blinded, sham-controlled trial evaluates whether a single injection of autologous platelet-rich plasma (PRP) into the distal anterior vaginal wall improves sexual function in women with sexual dysfunction. Sixty participants with a Female Sexual Function Index (FSFI) total score of 26.5 or lower are randomized 1:1 to PRP injection or sterile saline injection. Sexual function, sexual distress, global impression of change, and urinary incontinence symptoms are assessed at baseline, 6 weeks, and 6 months after injection.

Detaljeret beskrivelse

Participants complete baseline questionnaires at screening, followed by an in-person injection visit. All participants undergo a 40 mL whole blood draw to preserve blinding. For participants randomized to PRP, the blood is processed using a double-spin centrifugation protocol; for participants randomized to the control arm, the blood sample is discarded. Then 4 cc of PRP or sterile saline is injected with a 25-gauge needle just deep to the vaginal epithelium of the distal anterior vaginal wall, approximately 3 cm from the urethral meatus. Procedural pain is recorded before speculum insertion, during injection, and within 5 minutes after injection. Follow-up assessments at 6 weeks (±7 days) and 6 months (±14 days) may be completed virtually. Randomization uses permuted blocks of variable size (2 and 4), implemented in REDCap. After completing the 6-month follow-up, participants in the saline arm are offered PRP injection at no cost.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Participants receiving a PRP Injection

Participants will receive a single injection of 4-5cc autologous platelet-rich plasma into the distal anterior vaginal wall after blood draw.
Biologisk: Autologous Platelet-Rich Plasma (PRP) Injection

Whole blood draw of 40 mL is processed by double-spin centrifugation; 4 cc PRP is injected with a 25-guage needle just deep to the epithelium of the distal anterior vaginal wall, about 3 cm from the urethral meatus, after topical lidocaine.
Sham-komparator: Participants receiving Saline Injection

Participants will receive a single injection of 4-5cc sterile saline into the distal anterior vaginal wall after blood draw (blood sample will be discarded).
Andet: Sterile saline injection

4-5cc sterile saline injected at the same location, depth, and technique as the PRP arm, following a blood draw.

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Change in total score of The Female Sexual Function Index (FSFI)
Tidsramme: Baseline, 6 weeks, and 6 months after injection.

The Female Sexual Function Index (FSFI) is a 19-item questionnaire to evaluate female sexual function and dysfunction across 6 domains: desire, arousal, lubrication, orgasm, satisfaction, pain. Total scores range from 2.0-36.0; higher scores indicate better sexual function, and scores ≤26.5 indicate sexual dysfunction.
Baseline, 6 weeks, and 6 months after injection.

Foranstaltningsbeskrivelse
Tidsramme
Change in Female Sexual Distress Scale-Revised (FSDS-R) total score
Tidsramme: Baseline, 6 weeks, and 6 months after injection.

The Female Sexual Distress Scale-Revised (FSDS-R) is a 13-item questionnaire used to measure sexually related personal distress in adult women. Answers are scored on a scale of 0-4, with total scores ranging 0-52; higher scores indicate greater sexual distress, and scores ≥11 indicate clinically significant distress.
Baseline, 6 weeks, and 6 months after injection.
Patient Global Impression of Improvement (PGI-I)
Tidsramme: 6 weeks and 6 months after injection.

Patient Global Impression of improvement (PGI-I) is a single item scale assessing a patient's perception of change in their condition following treatment. The assessment is scored 1-7. Lower scores mean greater improvement. Scores of 1-3 are defined as a response.
6 weeks and 6 months after injection.
Change in FSFI domain scores
Tidsramme: Baseline, 6 weeks, and 6 months from injection visit.

The Female Sexual Function Index (FSFI) is a 19-item questionnaire to evaluate female sexual function and dysfunction across 6 domains: desire, arousal, lubrication, orgasm, satisfaction, pain. Domains are scored 0 (or 1.2) to 6.0. Total scores range from 2.0-36.0. Higher scores indicate better sexual function.
Baseline, 6 weeks, and 6 months from injection visit.
Stress Urinary Incontinence Symptom Frequency
Tidsramme: Baseline, 6 weeks, and 6 months from injection visit.

Among participants reporting incontinence: leakage frequency with activity is scored on a scale of 0 (never) to 5 (several times per day). Higher scores indicate more frequent leakage.
Baseline, 6 weeks, and 6 months from injection visit.
Visual Analogue Scale (VAS)
Tidsramme: Day of injection - before speculum insertion, during injection, and within 5 minutes after injection

The Visual Analogue Scale (VAS) is a single item questionnaire used to measure pain intensity. The assessment is scored on a scale of 0-10; higher scores indicate worse pain.
Day of injection - before speculum insertion, during injection, and within 5 minutes after injection
Number of participants with adverse events.
Tidsramme: From injection through 6 months.

Number of participants with treatment related adverse events post injection.
From injection through 6 months.
