Overseen ByManuel Molina, MD

Trial Summary

What is the purpose of this trial?

This trial is testing a combination of sound wave therapy and special injections to treat erectile dysfunction caused by poor blood flow in small vessels. The goal is to improve blood flow and repair blood vessels, enhancing erectile function. This approach targets patients who do not respond well to typical ED treatments.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are using certain hormone treatments or medications for psychiatric conditions, you may not be eligible to participate.

What data supports the effectiveness of the treatment Shockwave Therapy + Platelet Rich Plasma for Erectile Dysfunction?

Research shows that combining shockwave therapy with platelet-rich plasma (PRP) can improve erectile function and prolong the time before ejaculation in men with erectile dysfunction. Studies found that patients receiving this combination treatment had better sexual outcomes compared to those who did not, and it was considered safe.12345

Is Shockwave Therapy combined with Platelet Rich Plasma safe for treating erectile dysfunction?

Research indicates that combining Shockwave Therapy with Platelet Rich Plasma is generally safe for treating erectile dysfunction, with studies reporting no significant severe side effects.12356

How is the combination of shockwave therapy and platelet-rich plasma unique for treating erectile dysfunction?

This treatment is unique because it combines shockwave therapy, which uses sound waves to improve blood flow, with platelet-rich plasma (PRP) injections, which use components from your own blood to promote healing and tissue growth. This combination aims to enhance erectile function more effectively than either treatment alone, offering a novel approach for those who haven't responded to standard medications.12345

Findings from Research

The combination of low intensity external shock wave therapy (Li-ESWT) and platelet-rich plasma (PRP) therapy significantly improved outcomes in patients with acute Peyronie's disease, including reductions in plaque size and penile curvature, as well as enhancements in erectile function and pain scores.
This treatment was found to be safe, with no reported side effects such as ecchymosis or hematoma at the injection sites, indicating a favorable safety profile for early intervention in Peyronie's disease.
