Why these two get compared

They are sold from the same clinics, to the same men, with the same pitch: this treats the underlying cause rather than masking the symptom, and it is what the pharmaceutical industry does not want you to know about. Frequently they are sold together as a package.

The pitch is appealing because the underlying idea is legitimate. Regenerative approaches to erectile dysfunction are a real and active research field. The gap is between plausible mechanism and demonstrated clinical benefit — and that gap is where several thousand dollars of your money currently sits.

Where the evidence differs

Shockwave therapy
Multiple randomised, sham-controlled trials exist. They show modest average improvement in erectile function scores, concentrated in men with mild to moderate vasculogenic ED who already respond partly to tablets. Protocols vary so widely between studies that pooling them is difficult, and follow-up rarely extends beyond a year.
PRP and stem cell therapy
Most published work is small, single-arm and uncontrolled. The few sham-controlled PRP studies have not established a clear, durable advantage over placebo. Preparations are not standardised, so results from one clinic do not transfer to another.

If you are going ahead anyway

Some men will proceed regardless, and the safety profile in trials has been reassuring. Go in with your eyes open.

  • Which specific device or preparation is used, and what is its regulatory status?
  • What is the total cost, and what happens if there is no improvement?
  • Are outcomes measured with a validated instrument such as the IIEF, before and after?
  • Is a urologist involved, and have my other causes been investigated?
  • What published evidence supports this exact protocol — not the category in general?
  • Is there a clinical trial I could join instead? Trials are frequently free and better monitored — search ClinicalTrials.gov.
FAQ

Frequently asked questions

Is shockwave therapy better than PRP for ED?
It has better evidence — several sham-controlled trials showing modest benefit in mild vascular ED, which PRP currently lacks. Both are classed as investigational.
Are either FDA-approved for erectile dysfunction?
No. No shockwave device is approved or cleared for ED in the US, and PRP is not approved for this use either.
Will insurance cover them?
Essentially never, because both are considered investigational.
Is there anything that genuinely treats the cause?
Yes — exercise, weight loss, stopping smoking and glycaemic control improve endothelial function directly, with far better evidence and no cost. See lifestyle changes.
