The verdict
If you want the regenerative option with the most trial data, shockwave is the stronger pick, especially for mild vascular ED, with the clear caveat that the results are mixed and it is not FDA-cleared for ED. PRP suits men who understand it is earlier in its evidence, who accept injections, and who are often interested because a provider suggested it alongside shockwave or as a next step.
Neither one replaces proven treatments. Both are better thought of as options to discuss after an evaluation, not first-line care.
Side-by-side comparison
| Low-intensity shockwave | PRP injections (“P-Shot style”) | |
|---|---|---|
| What it is | Acoustic pulses applied to the penis | Your own platelet concentrate injected into the penis |
| Number of randomized trials | Dozens, most using focused devices | A handful, with small samples |
| What trials show | Mixed: some benefit over sham, some none | Conflicting: one positive, one no difference |
| FDA status for ED | Not cleared for ED | Not approved for ED |
| AUA position | Investigational | Experimental |
| Needles | None | Blood draw and injections, with numbing |
| Downtime | None | Little; mild soreness common |
How each one is meant to work
Shockwave sends low-energy acoustic pulses into penile tissue. The theory is that the mechanical stress prompts the growth of small blood vessels and improves how the tissue responds to arousal over the following weeks. PRP takes a different route: your blood is spun to concentrate platelets, which carry growth factors, and the concentrate is injected into the erectile tissue to encourage repair and better blood flow.
Both are sometimes grouped as restorative therapies because they aim to improve the tissue rather than produce a one-time erection. That aim is what makes them appealing, and also what makes them hard to study: results take weeks to appear and depend heavily on the cause of a man’s ED.
The evidence, trial by trial
Shockwave. A 2017 meta-analysis of seven randomized trials with 602 men found erectile function scores improved by 6.40 points on shockwave versus 1.65 on sham. A 2026 systematic review of 36 studies, 30 of them randomized, found that most tested focused shockwave and that results against sham were mixed, with some trials showing benefit and others none. Differences in protocols and outcome reporting kept the authors from firm conclusions. The 2017 analysis also found that results varied with the total number of shocks delivered, a hint that the protocol, not just the idea, shapes the outcome.
PRP. The data are thinner. In a Greek trial of 60 men with mild to moderate ED, 69% of the PRP group reached a meaningful improvement at six months versus 27% on placebo. A U.S. trial of 61 men using two PRP injections a month apart found no difference: 58.3% improved meaningfully on PRP and 53.6% on placebo. Both trials reported no major side effects. The authors of the positive trial cautioned that their single-center results may not carry over to other PRP preparation systems, which matters because platelet concentration and processing vary from one setup to the next.
The societies. The AUA guideline calls shockwave investigational and PRP experimental. The Sexual Medicine Society of North America found that shockwave has established relative safety but that robust efficacy data are lacking for restorative therapies, and recommended reserving them for clinical trials until better studies are done.

Why some men combine them
The logic for pairing is that shockwave may improve the blood vessel side while PRP adds growth factors to the tissue, so the two could add up. Some clinics use them together, and trials of the combination are under way, but no large controlled study has yet shown the pair beats either one alone. If combining appeals to you, ask how your progress will be measured and what the plan is if you do not respond. Our page on combining shockwave and PRP for ED covers the questions to raise.
Device choice matters for the shockwave half. Most trial data come from focused or linear machines, which is explained in focused vs radial shockwave for ED.
Comfort, side effects and cost
Shockwave feels like tapping on the skin, takes no anesthesia and has no downtime. PRP involves a blood draw and injections with numbing cream or local anesthetic; bruising and soreness for a day or two are the usual complaints. Any erection lasting more than four hours after any ED treatment is an emergency: go to the ER.
Neither is usually covered by insurance, because neither is approved for ED. Expect to pay directly, and ask for the cost of the full plan rather than a single session or injection. If the plan combines both treatments, ask whether the visits can be scheduled together, since that changes how much time off work the course takes as well as the total bill. Our page on PRP for ED cost explains what drives the price.
How Ultimate Male decides
Ultimate Male offers both low-intensity shockwave and PRP for ED, and the clinic is upfront that neither is FDA-approved for erectile dysfunction. The decision starts with a free 10-minute call, then a private consultation with a PA-C or MD and blood tests for erectile dysfunction, including testosterone, glucose and other markers that change the picture.
Your provider will explain which option fits the likely cause of your ED, how many visits are planned, how results will be judged and what the alternatives are, including proven medications. Learn more on the shockwave therapy and PRP injections for ED pages.
