Quick answer: Clinical research on platelet-rich plasma for erectile dysfunction is promising enough to justify continued study, but not strong enough to establish PRP as routine standard-of-care therapy. Trials are small, preparation methods vary, and results have not been consistent.
Why PRP is being studied for ED
PRP contains platelets and signaling proteins involved in tissue repair biology. Researchers have investigated whether these signals might influence vascular or erectile tissue. A biologically plausible mechanism, however, is not the same as proven clinical effectiveness.
What randomized studies have found
Some randomized studies have reported improvements in erectile-function scores after intracavernosal PRP, while others have not shown a significant advantage over placebo. Differences in platelet concentration, injection technique, number of sessions, baseline ED severity, and follow-up make studies difficult to compare.
What major guidelines say
The American Urological Association has classified PRP for ED as experimental. European guidance has noted mild improvements in some studies but insufficient evidence for routine recommendation. This is why we do not describe PRP as a cure or as superior to established ED therapy.
What patients should take from the evidence
PRP may ultimately prove useful for a subset of men, but we do not yet know the optimal candidate, dose, preparation, number of sessions, or durability. Men considering it should understand the uncertainty and should still receive an evaluation for cardiovascular, metabolic, hormonal, medication-related, neurologic, and psychological contributors.

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.
