There’s a version of men’s health marketing where everything works, the evidence is always positive, and the only question is how soon you’d like to book. That’s not how medicine operates, and it’s not how we operate at Dr. J Anti-Aging Clinic.
The P-Shot® a platelet-rich plasma (PRP) injection into penile tissue has a growing body of clinical research behind it. Some of that research is genuinely encouraging. Some of it raises honest questions about exactly how much benefit to expect, and for which patients. You deserve the complete picture.
What PRP Is Actually Doing in Penile Tissue
The biological premise is straightforward and grounded in well-established science. Platelet-rich plasma is derived from your own blood, processed to concentrate platelets at 5–10 times their normal levels. When injected into the corpus cavernosum the paired erectile chambers those platelets activate and release a cascade of growth factors: VEGF, PDGF, TGF-β, and others that stimulate angiogenesis (new blood vessel formation), smooth muscle cell repair, and tissue regeneration.
Vasculogenic erectile dysfunction the kind that develops gradually in men over 40, driven by diabetes, hypertension, cardiovascular factors, and age involves progressive damage to exactly this vascular and smooth muscle architecture. The P-Shot® attempts to address that damage directly, rather than masking its effects with medication.
The Clinical Studies What They Show
The Positive Evidence
The most meaningful recent analysis is a 2024 systematic review and meta-analysis by Mao et al. that examined 4 RCTs involving 413 patients, drawn from PubMed, Embase, Cochrane, and Web of Science. The analysis found that PRP showed statistically significant advantage over placebo in IIEF minimum clinically important difference (MCID) at months 1 and 3. These are the highest-quality studies in the literature, analyzed together and the result favors PRP.
Mao et al., 2024. PMID: 38832665
A 2023 RCT by Shaher et al. reinforced this picture. 100 men with mild-to-moderate ED received three PRP injections or saline placebo. The PRP group demonstrated significantly greater improvements in IIEF scores and sexual encounter success rates at 6-month follow-up.
Shaher et al., Urology, 2023. PMID: 36736914
A 2024 PRISMA-compliant systematic review by Andrade et al. analyzed 17 studies totaling 1,099 patients across both ED and Peyronie’s disease applications. The overall conclusion: PRP studies generally showed small but statistically meaningful improvements in erectile function outcomes versus placebo.

The Conflicting Evidence Masterson 2023
⚠️ EVIDENCE NOTE:
The most methodologically rigorous trial to date Masterson et al. at the University of Miami Desai Sethi Urology Institute, published in Journal of Urology, 2023 found no statistically significant difference between PRP and placebo on primary IIEF-EF outcomes. This is the hardest trial to explain away, and it matters. It doesn’t mean PRP doesn’t work; it does mean that individual patient response varies, that methodology differences between trials produce different results, and that anyone claiming guaranteed outcomes for P-Shot® is overstating the evidence.

What This Means in Practice at Dr. J Anti-Aging Clinic
I present both the encouraging and the conflicting evidence to every patient I consult before the P-Shot® discussion goes further. Here’s my clinical read: the Mao 2024 meta-analysis combining the best RCT data suggests meaningful benefit for patients in the mild-to-moderate vasculogenic ED profile. The Masterson negative trial used a more rigorous design and introduced important uncertainty. Both are real.
- DR. J:
The men who respond best to the P-Shot® in my practice are those with mild to moderate vasculogenic ED who are committed to the full regenerative protocol not looking for an instant single-injection fix. Managing that expectation honestly is part of my job.
P-Shot® for Peyronie’s Disease
PRP has a secondary application in Peyronie’s disease the condition causing penile plaque formation, curvature, and painful erections. Published data suggests PRP may reduce plaque density and improve curvature in some patients, with a more consistent pain reduction effect. For men dealing with both ED and Peyronie’s, the P-Shot® is worth discussing as part of a combined approach particularly alongside MENZ Wave® acoustic wave therapy, which also has published evidence for both conditions.
The Combination Advantage
The most compelling data for PRP in ED comes from its combination with acoustic wave therapy. A 2024 systematic review presented at the Sexual Medicine Society of North America found that LiSWT + PRP produced a mean IIEF improvement of +8.2 versus control compared to +3.4 for wave therapy alone and +3.2 for PRP alone. The two treatments address complementary mechanisms, and the combined effect is genuinely additive in the evidence.
For patients in Central Florida Orlando, Winter Park, Kissimmee, Dr. Phillips, and beyond who are looking for the strongest available non-surgical regenerative approach, the MENZ Wave® + MENZ Shot™ combined protocol represents the current evidence ceiling.
