Sexual concerns are among the most common reasons women seek care in gynecology, menopause, functional and aesthetic medicine practices. In the National Health and Social Life Survey, Laumann, Paik and Rosen reported sexual dysfunction in 43 percent of women aged 18 to 59 in 1999, and the PRESIDE survey of 31,581 women by Shifren and colleagues in 2008 found that 43.1 percent reported a sexual problem and 12.0 percent a problem that caused them distress, a share that reached 14.8 percent between ages 45 and 64.

Regenerative biologics are studied in this area in three forms: platelet-rich plasma injected into the anterior vaginal wall, the clitoral region or the vulva; adipose-derived cells and fat grafting for vulvar disease; and umbilical cord mesenchymal stromal cells and their extracellular vesicles, studied mainly in menopause and ovarian models. This review sets out the physiology each targets, what the clinical trials report domain by domain, what the preclinical vesicle literature shows about blood flow and tissue, the registered trials, and the documentation a practice keeps. It is written for gynecology, urogynecology, menopause, aesthetic and regenerative practices and for investigators.

Regulatory position, stated once

PRP prepared at the point of care is a blood component, which 21 CFR 1271.3(d)(2) excludes from the definition of HCT/Ps, and PRP preparation systems reach the US market through 510(k) clearance under product code ORG, whose cleared indication is mixing with bone graft. The FDA states that there are no FDA-approved exosome products, and allogeneic umbilical cord or Wharton's jelly cell products used for treatment generally fall outside the four criteria of 21 CFR 1271.10(a) and follow the biologics pathway. Which material, for which patient and by which route are practitioner decisions this article does not make, and ExaVeyra Sciences supplies exosome material for topical aesthetic use by licensed practitioners and for IND-authorized research.

Desire, arousal and orgasm rely on blood flow, nerve supply and estrogen-responsive tissue

Genital arousal in women is a neurovascular event that parallels the male response. Nitric oxide and vasoactive intestinal polypeptide relax the smooth muscle of the clitoral corpora and the vaginal wall, inflow rises, the clitoris engorges and plasma transudate across the vaginal epithelium provides lubrication, a sequence that the clitoral anatomy work of O'Connell and colleagues placed in a larger erectile complex than older texts described.

Sensation travels mainly through the dorsal nerve of the clitoris, a branch of the pudendal nerve, while desire is governed centrally and is shaped by hormones, mood, relationship context and medications. The vulvovaginal tissue itself is estrogen-dependent, so the fall in estradiol at menopause thins the epithelium, reduces blood flow and lubrication and raises the vaginal pH, the cluster now named genitourinary syndrome of menopause. Regenerative research has concentrated on that tissue and vascular level, which is why most trials measure arousal, lubrication, pain and tissue quality more often than desire.

Because these components are separate, trial endpoints differ widely. The Female Sexual Function Index (FSFI) scores desire, arousal, lubrication, orgasm, satisfaction and pain separately, with a total up to 36 and a cutoff of 26.55 commonly used to identify dysfunction, so the trials below are described by the domains they actually reported.

PRP has moved from pilot series to randomized trials in four areas of women's sexual health

Sexual function: from an 11-patient pilot to a saline-controlled trial

The PRP literature in female sexual function began with an 11-woman pilot by Runels and colleagues in 2014, which reported a rise in total FSFI from 24.13 to 29.63 at 12 to 16 weeks after injection near the clitoris and the anterior vaginal wall, with gains in the arousal, lubrication and orgasm domains. Two participants reported transient heightened arousal that resolved within one to two weeks, and the first author originated the trademarked procedure the study describes.

Sukgen and colleagues reported a larger retrospective series in 2019, 52 women with sexual dysfunction or orgasmic disorder treated with four monthly PRP sessions to the lower anterior vaginal wall and peri-clitoral area. Total FSFI rose from 13.61 to 27.88 at six months, the orgasm domain from 2.11 to 4.48, every domain improved, half the women reached a total FSFI of 26 or above afterwards, and no adverse effects were reported.

The first saline-controlled randomized trial of vaginal PRP for sexual function in premenopausal women was published by Clarke, Dieter and colleagues at MedStar in 2026 (NCT05769283). It randomized 52 sexually active premenopausal women to one anterior vaginal wall injection of PRP or saline, and reported a median FSFI change of 2.2 with PRP against 0.3 with saline at six weeks (P = .05), with 69.2 percent of the PRP group reporting improvement on the Patient Global Impression of Improvement at six months against 34.6 percent with saline (P = .01). Subdomain differences did not reach significance after adjustment, injection was more painful with PRP, and there were no serious adverse events. Dankova and colleagues had earlier systematically reviewed 12 studies of 327 women in 2023 and reported improvement in most of the sexual dysfunction studies and in all seven incontinence studies, with minor adverse events in under 1 percent, while calling for high-quality randomized trials of the kind that has now begun to appear.

Genitourinary syndrome of menopause and vulvovaginal atrophy

In postmenopausal women with vulvovaginal atrophy, Abdel Hamid and colleagues at Ain Shams University randomized 60 women to vaginal mucosal PRP or saline (NCT03898401) and reported a total FSFI of 19.0 against 9.7 at four months (P < .001), with significant gains in lubrication, satisfaction and pain and no significant difference in desire, arousal or orgasm. The authors describe the study as a pilot.

Breast cancer survivors, for whom vaginal estradiol is often avoided or used only after oncology review, are a group of particular research interest. Hersant and colleagues treated 20 survivors with PRP combined with hyaluronic acid in a 2018 phase 2 pilot and reported a significant rise in the Vaginal Health Index and a 17 percent fall in sexual distress at six months, without adverse events. Chen, Trabuco and colleagues at Mayo Clinic gave 20 survivors a single diffuse vaginal PRP injection in a phase 1 study (NCT04535323), reported that every participant tolerated it, and found improvement in all secondary measures at weeks 4, 12 and 26 except the vaginal maturation index, with no difference between women taking aromatase inhibitors and those who were not. Waghe and colleagues reviewed the GSM literature in 2024 and found the strongest signals for PRP in combination protocols.

Vulvar lichen sclerosus

Lichen sclerosus scars the vulva, can bury the clitoris and narrow the introitus, and so bears directly on sexual function. Goldstein and colleagues reported reduced inflammation on biopsy in 7 of 12 women after intradermal PRP in 2017, and Tedesco and colleagues reported in 2022 that, among 51 women in a 94-patient cohort, pain fell from 33.3 to 7.8 percent, burning from 51.0 to 15.7 percent and itching from 80.4 to 21.6 percent, with no adverse outcomes. Medina Garrido and colleagues reported mid-term relief of itching, burning and soreness in 23 women in 2023.

The one double-blind randomized trial to date, by Goldstein and colleagues in 2019 (NCT03045172), compared PRP with saline in 29 women (19 PRP, 10 saline) and found no statistically significant difference between arms in histologic inflammation or in patient-reported symptom scores, which improved in both arms. Beutler and colleagues reviewed 13 regenerative studies of 360 women in 2025 and concluded that PRP, adipose-derived cells and mesotherapy may help, and a 68-patient double-blind trial in Adelaide whose protocol was published in 2025 closed enrollment early at 34 participants because of slow recruitment, with results expected.

Stress urinary incontinence and sexual confidence

Incontinence during intercourse is a frequent and under-reported concern, and PRP to the anterior vaginal wall near the mid-urethra is now in randomized trials. Athanasiou and colleagues randomized 50 women to PRP or sham in 2024 and reported subjective cure in 32 percent with PRP against 4 percent with sham (P < .001), with greater pad-test improvement at six months. Saraluck and colleagues added PRP to pelvic floor muscle training in 60 women and reported about 8 g more reduction in pad weight at five months, Ashton and colleagues found no significant difference between a single PRP injection and saline in 50 women, and Long and colleagues reported 60 percent success at six months in a 20-woman series, in which FSFI rose from 17.9 to 20.3 without reaching significance.

Cell-based studies span vulvar tissue, continence and ovarian function, and umbilical cord cells lead the ovarian work

Fat grafting and adipose-derived cells in vulvar lichen sclerosus

Adipose tissue carries stromal vascular fraction cells and adipose-derived stromal cells, and it is the most clinically studied cell source in vulvar disease. Boero and colleagues treated 36 women with autologous fat grafting between 2011 and 2014 and reported improved vulvar trophism in 94 percent, better introital caliber and elasticity in 75 percent, reduced clitoral burying in half, and significant gains in quality of life and FSFI, with most patients able to stop routine topical steroids.

Monreal reported 39 women treated with stromal vascular fraction enriched fat grafting in 2020, with improvement in 94.9 percent and a fall in the global symptom score from 93.56 to 43.59 at 24 months, alongside a fall in the sexual functioning subscore from 15.64 to 8.44, where lower scores indicate fewer symptoms. Almadori and colleagues reported improved sexual function, pain, itching and tissue architecture in a 33-woman prospective cohort treated with autologous fat grafting in 2020.

Autologous muscle-derived cells in stress urinary incontinence

The largest cell trial in female pelvic health is the phase 3 iltamiocel study reported by Kaufman and colleagues in 2024 (NCT01893138), which randomized 297 women 2:1 to 150 million autologous muscle-derived cells or placebo. The primary endpoint was similar between arms, 52 against 53.6 percent achieving at least a 50 percent reduction in stress episodes, and in the prespecified subgroup with prior incontinence surgery 40 percent of the cell group reached a 75 percent reduction against 16 percent with placebo (P = .037).

Umbilical cord MSCs and ovarian function

Umbilical cord mesenchymal stromal cells, most often isolated from Wharton's jelly, are the cell population studied most in ovarian research, which bears on sexual health through the hormonal environment that supports desire and vulvovaginal tissue. Yan and colleagues treated 61 women aged 35 or younger with premature ovarian insufficiency using ultrasound-guided intraovarian umbilical cord MSC injection in 2020 (NCT03033277), and reported mature follicles in 31.1 percent after the first injection, any follicular development in 67.2 percent, better response with shorter amenorrhea, and four deliveries, with five mild and transient adverse events.

The Wharton's jelly source guide on this blog explains why the perivascular cord tissue yields a young-donor, HLA-DR negative cell population with a characteristic secretome, and why the tissue origin of a cell or vesicle product should be stated on its documentation. Published human gynecologic studies have described their cells as umbilical cord MSCs without always naming the cord compartment, and a registered phase 1 study of autologous stromal vascular fraction and PRP for ovarian rejuvenation, NCT04444245, lists 100 planned participants.

Vesicle research reports thicker vaginal epithelium, new microvessels and restored ovarian markers in animal models

Extracellular vesicles carry the proteins, microRNAs and lipids of the cells that secrete them, and the women's health literature has studied umbilical cord MSC vesicles in particular. Zhang and colleagues delivered umbilical cord MSC exosomes in a hydrogel to ovariectomized rats in 2023 and reported a thicker vaginal epithelium than in untreated ovariectomized animals, more proliferating cells by Ki67 and more microvessels by CD31, without a uterotrophic effect; estradiol restored epithelial thickness closer to that of intact animals, which gives the exosome result a useful reference point.

The vascular side of arousal now has a dedicated model. Li and colleagues established a rat model of female genital sexual arousal disorder in 2022 by combining vaginal dilatation with ovariectomy, and reported the largest fall in nerve-stimulated vaginal blood flow in that group, with lower smooth muscle actin, vessel density and VEGF and disrupted collagen and elastic fibers, endpoints that make blood flow measurable when biologics are tested. Ben Menachem-Zidon and colleagues reported in 2019 that bone marrow MSCs homed to a vaginal wound in rats and nearly doubled vessel counts, from 4.2 to about 8 per field, with donor-derived cells forming close to a quarter of the vessels.

In ovarian models the vesicle work is more mechanistic. Li and colleagues reported in 2021 that umbilical cord MSC exosomes moved AMH, estradiol and FSH toward normal and improved follicle counts and fertility in mice with chemotherapy-induced ovarian insufficiency through the Hippo pathway, with the effect abolished when YAP signaling was blocked, and Zhou and colleagues reported in 2024 that umbilical cord MSC exosomes reduced ferroptosis through the Nrf2 and GPX4 pathway in the same model.

StudyModelMaterialReported result
Zhang 2023Ovariectomized ratUmbilical cord MSC exosomes in hydrogelThicker epithelium, more Ki67 and CD31 staining, no uterine stimulation
Li 2022Rat arousal disorder modelModel developmentVaginal blood flow, smooth muscle, VEGF and collagen as measurable endpoints

Zhou 2024Mouse ovarian insufficiencyUmbilical cord MSC exosomesOvarian markers improved; ferroptosis reduced via Nrf2 and GPX4

The human vesicle literature in women's sexual health has yet to report a controlled trial, so these animal results describe mechanisms under investigation, and a vesicle product's source cell, isolation method and characterization by lot determine which of these studies it can be compared with.

The orgasmic disorder trial is the only study in this table to name orgasm as its primary target. Its double-masked design compares peri-urethral and clitoral PRP with placebo, and its results would address the domain studied least so far.

The evidence base is early and expanding quickly

  • Randomized trials have arrived in the last three years. Clarke 2026, Abdel Hamid 2025, Athanasiou 2024, Saraluck 2024 and Ashton 2024 join the 2019 lichen sclerosus trial, and most enrolled 29 to 60 women.
  • Endpoints differ by domain, and lubrication, pain and tissue quality respond most often in the published studies, while desire is measured less often and orgasm has one dedicated registered trial.
  • Preparations vary, since studies used different kits, spin protocols, volumes, injection sites and session counts, so each result belongs to the preparation that produced it, as the 2025 scoping review by Willison and colleagues noted.
  • Follow-up is typically four to six months, with Monreal's 24-month fat grafting series and the 24-month iltamiocel durability data the longest.
  • Several early studies were authored by originators of the procedures they describe, which the annotated references record, and the newer saline-controlled trials come from academic centers.
  • Umbilical cord MSC and vesicle data in genital tissue are preclinical, and the human umbilical cord data come from ovarian studies.

No PRP system, cell product or exosome product is FDA-approved for a sexual-health indication

PRP prepared at the point of care is a blood component, excluded from the definition of HCT/Ps by 21 CFR 1271.3(d)(2), and its preparation systems are cleared through 510(k) under product code ORG for mixing with bone graft, so a gynecologic use is a practitioner's off-label decision. Allogeneic cell products, including umbilical cord and Wharton's jelly cells, are regulated solely under section 361 only when they meet all four criteria of 21 CFR 1271.10(a), and, per the FDA, products used for treatment generally follow the biologics pathway.

The FDA consumer alert on regenerative medicine products, current as of April 2024, states that there are no FDA-approved exosome products, and the agency's December 2019 public safety notification states that exosomes used to treat diseases and conditions are regulated as drugs and biological products. The agency's July 2018 communication on energy-based vaginal rejuvenation devices is relevant context for any practice that combines biologics with lasers or radiofrequency, because it stated that the safety and effectiveness of those devices for such procedures had not been established.

Documentation each practice records

  • The FSFI, FSDS-R or condition-specific instrument used, with baseline and follow-up dates, so that results can be read domain by domain
  • For PRP: kit name, 510(k) number, lot, anticoagulant, centrifuge model, relative centrifugal force and time, volume and injection sites
  • For fat grafting or stromal vascular fraction: harvest site, processing device and volume placed
  • For exosome material: product name, source cell and tissue, lot number, certificate of analysis on file, storage temperature log and time from thaw to application
  • Menopausal status, hormone use and, for survivors of breast cancer, endocrine therapy, since both shape vulvovaginal tissue

ExaVeyra Sciences supplies exosome material with the lot number and storage requirements on every order and the certificate of analysis for each lot available on request, so that a practice can file them against the record above. Randomized trials, standardized instruments and registered protocols are now arriving together in women's sexual health, and the practices that document their preparations carefully will be best placed to read each new result against their own work.

Frequently Asked Questions

Does PRP improve female sexual function?
In the first saline-controlled randomized trial in premenopausal women, Clarke and colleagues reported in 2026 a median FSFI change of 2.2 with PRP against 0.3 with saline at six weeks in 52 premenopausal women (P = .05), and 69.2 against 34.6 percent reporting global improvement at six months. Earlier uncontrolled series reported larger FSFI gains, and a 2023 systematic review of 12 studies reported improvement in most of them.
What is the O-Shot and what does the research say?
The trademarked name refers to PRP injected near the clitoris and anterior vaginal wall. The 2014 pilot by its originator reported a rise in FSFI from 24.13 to 29.63 in 11 women, and a 2019 series of 52 women reported FSFI rising from 13.61 to 27.88 at six months after four sessions.
Can PRP help with orgasm or sensitivity?
Sukgen and colleagues reported the orgasm domain rising from 2.11 to 4.48 in 52 women in 2019, and Runels and colleagues reported a gain in the orgasm domain in their pilot. A double-masked randomized trial of peri-urethral and clitoral PRP for female orgasmic disorder is registered as NCT03189238.
Does PRP help vaginal dryness and painful intercourse after menopause?
Abdel Hamid and colleagues randomized 60 postmenopausal women with vulvovaginal atrophy and reported significant gains in lubrication and pain domains with PRP against saline at four months. The Menopause Society's 2020 position statement places lubricants and moisturizers first for genitourinary syndrome of menopause, with low-dose vaginal estrogen recommended for moderate to severe symptoms or when those options are not enough.
Is PRP being studied for breast cancer survivors with vaginal atrophy?
Yes. A Mayo Clinic phase 1 study in 20 survivors reported that a single vaginal PRP injection was tolerated by everyone treated and that secondary measures improved through 26 weeks, and a 2018 pilot of PRP with hyaluronic acid in 20 survivors reported a 17 percent fall in sexual distress.
What does the research show for lichen sclerosus?
Cohort studies reported falls in pain, burning and itching after PRP and improved trophism and sexual function after fat grafting. In the one double-blind trial, both PRP and saline arms improved without a significant difference between them, and a further double-blind trial in Australia closed enrollment early at 34 of 68 planned participants.
Are stem cells or Wharton's jelly used for female sexual dysfunction?
Human studies of cells in women's sexual health have used adipose-derived cells and fat grafting for vulvar disease, muscle-derived cells for incontinence, and umbilical cord MSCs for ovarian insufficiency. Umbilical cord cells, usually isolated from Wharton's jelly, have been studied in vaginal tissue in animal models.
What do exosomes do in vaginal atrophy research?
In ovariectomized rats, umbilical cord MSC exosomes delivered in a hydrogel thickened the vaginal epithelium and increased proliferating cells and microvessels without stimulating the uterus, as Zhang and colleagues reported in 2023. No controlled human trial has yet been published.
Are exosomes FDA-approved for women's health?
No exosome product is FDA-approved for any use, as the FDA consumer alert current as of April 2024 states. Exosome material is supplied for topical aesthetic use by licensed practitioners and for IND-authorized clinical research.
Does PRP help with bladder leakage during sex?
Athanasiou and colleagues reported subjective cure in 32 percent of women after PRP against 4 percent after sham in 2024, and Saraluck and colleagues reported added benefit when PRP joined pelvic floor training. A single-injection trial by Ashton and colleagues found no significant difference from saline.
