Quick answer: PRP injections and low-intensity shockwave therapy are different investigational or emerging approaches for ED. Shockwave therapy has been studied more extensively in vasculogenic ED, but protocols and long-term outcomes remain variable. PRP evidence is more limited.
How the approaches differ
| Feature | PRP | Low-intensity shockwave |
|---|---|---|
| Method | Autologous platelet concentrate injected into penile tissue | External acoustic-energy treatment |
| Injections | Yes | No |
| Evidence base | Limited and inconsistent | Larger but still heterogeneous |
| Standardized protocol | No | No universal protocol |
| Established replacement for PDE5 inhibitors | No | No |
Which has stronger evidence?
Low-intensity shockwave therapy has a broader clinical literature, particularly for vasculogenic ED, but results depend on device type, energy settings, patient selection, and protocol. PRP has fewer high-quality controlled studies. Neither should be marketed as a guaranteed regenerative cure.
Why diagnosis still comes first
Neither approach substitutes for evaluating cardiovascular disease, diabetes, testosterone status when appropriate, medication effects, neurologic causes, or psychological contributors. A patient with severe arterial disease or post-surgical neurovascular injury may have a very different prognosis from a patient with mild vasculogenic ED.

Important: PRP for sexual-function concerns is investigational/off-label. Evidence is limited and heterogeneous, and PRP should not be presented as a proven cure or replacement for established evaluation and treatment.
