Note: As of August 2025, we’ve moved this section from our article on “New and Experimental Treatments for Erectile Dysfunction” to create this standalone article. At that time, we found that the high level of interest in PRP justified a detailed discussion.
PRP (Platelet-Rich Plasma) therapy is a treatment for erectile dysfunction (ED) that uses a patient’s own blood to potentially improve sexual function. The therapy involves drawing a small amount of blood from the patient and processing it to concentrate the platelets. These platelets contain growth factors that in theory can stimulate tissue regeneration and potentially improve blood flow to the penis. The concentrated PRP is then injected into specific areas of the penis.
The treatment is performed in a clinic. Typically, two or more injections are administered over a period of several weeks.
Clinical Studies of PRP Therapy for Erectile Dysfunction
PRP therapy is now widely promoted by clinics. However, the evidence for the effectiveness of the procedure is not conclusive.
A review of the research, conducted in 2019, concluded that “Despite a global presence of PRP clinics and ongoing active marketing and public interest in regenerative medicine, no scientific evidence has been published to establish an evidence-based risk-benefit profile for PRP use for ED in humans.”
Another research review, conducted in 2022, concluded that “PRP injections for the treatment of ED may be promising, but no recommendation can be made because of scarce evidence. Safety and effectiveness of this therapy in the treatment of ED and PD require further preclinical and clinical studies with standardized protocols to gain an adequate insight into its potential implications.”
A 2023 study found no difference between PRP therapy and a placebo. A 2024 study found benefits that met the minimal threshold for statistical relevance, but concluded that “the current data do not justify PRP in clinical practice.”
Finally, a 2025 review pooled 28 studies (through June 2024) and concluded that PRP delivered small benefits over placebos with few adverse effects reported. However, the study stressed that there was little uniformity across studies and limited long-term data, so PRP remains experimental.
Risks
Because PRP therapy uses the patient’s own blood, the risk of allergic reactions or rejection is very low.
Reported side effects are generally mild and temporary, such as pain or bruising at the injection site. There have been no major adverse events noted in rigorous studies.
Conclusions
Studies suggest that PRP therapy is safe, and may deliver modest, short-term benefits for men with mild-to-moderate vascular erectile dysfunction.
Most studies are small, single-arm or cohort studies. A few randomized, placebo-controlled trials exist (e.g., Masterson et al., 2023), but overall evidence remains limited. Moreover, the studies have used a wide range of methodologies and treatment protocols, so there is no established standard of care.
The American Urological Association and the European Association of Urology categorize PRP for Erectile Dysfunction as experimental. They advise that the procedure should only be undertaken as part of a regulated clinical trial.
