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

Platelet-rich plasma is a substance derived from the participants' own blood and is not considered a drug. It is created through centrifugation of a participant's whole blood to separate out red blood cells leaving a concentrated plasma product containing the participant's natural endogenous growth factors and cytokines. PRP has been studied and found to be effective and safe without serious side effects in specialties such as orthopedics and dermatology. It is unclear if PRP injections to the anterior vaginal wall and clitoris improves sexual function and stress urinary incontinence. To date, the only literature on this is a single arm unblinded study.

This will be a single-blinded randomized controlled trial. Our primary objective is to determine if platelet rich plasma (PRP) injections into the anterior vaginal wall and periclitoral tissues boosts sexual satisfaction in sexually active women without a history of female sexual dysfunction (FSD). Our secondary objective is to determine the effect of PRP injections on sexual function. Qualifying subjects will be randomized 1:1 in permutated blocks to receive either PRP injection or placebo control (sterile saline injection). They will be followed for 6 month in the following fashion:

Visit #1: Screening, Baseline & Enrollment (virtual visit) This visit will be done virtually. Premenopausal sexually-active women meeting the listed inclusion criteria and exclusion criteria will view a short powerpoint orienting them to the research study and offer background about PRP and its proposed benefit for sexual function. Afterwards, a research team member will review the study and informed consent form, answer any questions, and, if they are interested in participating, the coordinator will obtain verbal informed consent and document verbal consent, and enroll the subject. The subject will then be asked to complete a series of questionnaires.

Visit #2: Randomization & Intervention (in-person visit) Subjects attending the in-person second visit will sign the informed consent form and then be randomized to either intervention (PRP) injection or placebo (injectable saline). The subject will be blinded to the treatment allocation.

- Blinding: This is a single-blinded study. The subject will not know whether they are giving or receiving PRP. The injector will be aware. The code will be broken only after the study is complete. At this point all the research team will be made aware of the results. During the study, the blinding may be broken only in emergencies when knowledge of the subject's treatment group is necessary for further subject management. When possible, the Investigator will discuss the emergency with the monitor (the IRB) prior to unblinding.
