The Core Difference
| P-Shot (PRP) | Penile filler |
|---|
| Treats | Erectile function | Girth / appearance |
| Material | Your own platelets | Dermal filler |
| Adds size? | No | Yes — circumference only |
| Improves erections? | Possibly, modestly | No |
| Onset | 12–24 weeks | Immediate |
| Duration | Variable, months | 12–24 months, or permanent |
| Reversible? | N/A | Yes, if hyaluronic acid |
Why This Confusion Exists
Marketing. The P-Shot is frequently advertised alongside enlargement services, and some clinics imply a size benefit that the procedure does not deliver. The published trials measure erectile function scores, not circumference.
The Google question "does the P-Shot increase size permanently?" is asked constantly, and the honest answer is that it is not a size treatment at all — so permanence does not apply.
How to choose
If your concern is how it looks — girth, appearance, proportion — that is filler.
If your concern is how it works — achieving or maintaining an erection — that is an erectile dysfunction evaluation first, then possibly the P-Shot or other treatment.
If it is both, they can be done, but the function workup should come first. A vascular cause found during that assessment matters more than either procedure.
Evidence, Compared
P-Shot: a 2025 meta-analysis of seven randomized trials (660 patients) found significant improvement in erectile scores at 12 and 24 weeks; a 2024 review of four studies found no conclusive evidence. Preparation varies widely between clinics. Small to moderate benefit.
Filler: a 301-patient comparison found girth gains of 2.1 to 2.9 cm depending on material, with adverse events in 7 to 14%. No FDA-approved product exists for this indication.
Neither is a settled, well-regulated field. Both deserve the questions in our safety article.
Can You Have Both?
Yes, though not usually in the same session, and the sequence matters. If erectile function is a concern, evaluate and address that first — partly because the workup may reveal something requiring medical management, and partly because it is difficult to judge satisfaction with appearance while function is a worry.
Dr. Daniel Moghadam will map a sequence rather than sell you both at once.
