Regenerative Therapies for Erectile Dysfunction: PRP and Shockwave in 2024
Erectile dysfunction affects over 30 million men in the United States, as reported by the Urology Care Foundation. Traditionally, treatments have included oral medications, lifestyle changes, and surgical options like penile implants. However, in 2024, attention is shifting toward regenerative therapies that promise to address ED at its source, not just its symptoms.
Two leading non-invasive treatments — Platelet-Rich Plasma (PRP) and Low-Intensity Shockwave Therapy (LiSWT) — are emerging as promising solutions. But how well do these therapies actually work? Let’s delve into the current state of the science and explore what men should know before considering regenerative options.
Understanding Erectile Dysfunction and Regenerative Medicine
Erectile dysfunction often stems from reduced blood flow, nerve damage, or psychological factors. While common ED medications like Viagra and Cialis work by temporarily improving blood flow, they don’t address underlying causes of ED. Moreover, these medications are only effective for about 60 to 70 percent of men, and side effects can limit long-term use.
Regenerative therapies approach ED differently. Rather than offering momentary support, they stimulate the body’s natural healing processes to improve function over time. By promoting tissue repair and vascular regeneration, options like PRP and shockwave therapy may help men regain natural, spontaneous erections.
“Regenerative therapies are changing the landscape for ED by focusing on healing at the cellular level,” notes Dr. Jonathan Levine, board-certified urologist and lecturer at NYU Langone Health.
What Is PRP Therapy for ED?
Platelet-Rich Plasma therapy, also known as the “Priapus Shot” or “P-Shot,” involves drawing a small amount of a man’s blood, spinning it in a centrifuge to concentrate platelets, and then injecting the resulting plasma into targeted areas of the penis. These platelets are rich in growth factors that may help invigorate tissue and encourage blood vessel and nerve regeneration.
Potential benefits of PRP therapy include:
– Enhanced blood circulation
– Nerve regeneration
– Increased penile sensitivity
The procedure is quick — typically completed in 30 to 45 minutes — and is usually well-tolerated due to the use of a local anesthetic.
Is There Evidence That PRP Therapy Works?
Though still considered an “off-label” treatment and not FDA-approved, early studies suggest PRP therapy may help men with mild to moderate ED. A 2020 review in The Journal of Sexual Medicine found consistent improvements in International Index of Erectile Function (IIEF) scores across several small-scale studies.
One such study revealed a 20 to 25 percent improvement in erection strength within three months of treatment. However, more large-scale, double-blind clinical trials are necessary to establish definitive safety and efficacy.
Example: A 48-year-old man with mild ED caused by hypertension turned to PRP after struggling with side effects from oral medications. Within two months and three treatment sessions, he reported firmer erections and increased sensitivity.

What Is Low-Intensity Shockwave Therapy?
Low-Intensity Shockwave Therapy (LiSWT) is a needle-free solution that uses sound wave technology to stimulate blood vessel formation in the penis. During this treatment, a device delivers controlled acoustic pulses to the penile tissue, encouraging new blood vessel growth — a process known as angiogenesis.
A typical course of treatment includes six to twelve sessions, each lasting about 20 minutes. These treatments are usually spaced over three weeks to three months.
LiSWT aims to restore erectile function by enhancing blood flow — all without the need for daily ED medication.
How Effective Is LiSWT?
Clinical research supports the potential of shockwave therapy. A meta-analysis published in the International Journal of Impotence Research (2021) found statistically significant improvements in erectile function for men with vasculogenic ED. Improvements in IIEF scores averaged between 6 to 8 points in men with mild to moderate ED.
Even more promising, these improvements often last between six to twelve months, although some men may benefit from periodic maintenance sessions.
According to Dr. Natalie Parker, a sexual medicine specialist and American Urological Association contributor, “Shockwave therapy has one of the strongest evidence bases among the regenerative treatments for ED.”
LiSWT has gained earlier acceptance in Europe; in 2017, the European Association of Urology recognized it as a valid treatment for certain types of ED. While it is also practiced widely in the United States, it has yet to receive full FDA approval specifically for ED.
Example: A 55-year-old man with diabetes-related ED experienced a significant improvement in erectile quality after completing a 12-session shockwave routine, reducing his need for medication.
Combining PRP with Shockwave Therapy: A Dual Approach
A rapidly growing trend in ED treatment is the combination of PRP and shockwave therapy. Since both techniques aim to restore vascular and tissue health, using them together may enhance overall benefits.
Preliminary research indicates that combining therapies could lead to greater gains. In one early trial, men who received both treatments reported a 43 percent increase in erection firmness, compared to 24 percent in those who only received PRP.
“This is a multi-modal approach, much like how we manage complex medical conditions — combining strategies for more robust results,” explains Dr. Jeffry Palmer, a regenerative medicine expert and urologist at Johns Hopkins.
Who Makes a Good Candidate for Regenerative ED Therapies?
While promising, these regenerative treatments may not be suitable for everyone. Ideal candidates include:
– Men experiencing mild to moderate ED
– Those with ED linked to aging or vascular issues
– Individuals seeking non-pharmaceutical therapies
However, men with severe nerve damage (such as post-prostatectomy patients) or poorly controlled diabetes may see limited effectiveness, although combined approaches with traditional methods might still help.
It’s critical to choose a provider with specialized training in sexual medicine. Beware of unregulated clinics advertising “miracle cures” without offering true medical oversight.

The Future of Regenerative Treatments: What’s on the Horizon?
Regenerative medicine in urology is evolving quickly. Current research focuses on refining techniques, such as:
– Determining optimal PRP injection intervals
– Tailoring shockwave dosing schedules
– Identifying biomarkers to predict patient response
Moreover, new modalities — including stem cell therapy and exosome treatments — are under investigation. These future options may complement existing approaches like PRP and LiSWT, leading to comprehensive protocols rebuilding blood vessels, nerves, and smooth muscle in unison.
Large-scale clinical trials underway in 2024 and beyond aim to provide standardized treatment guidelines and more consistent outcomes.
Conclusion: Advancing Toward Restorative Solutions
PRP and low-intensity shockwave therapy mark a significant shift in how erectile dysfunction is addressed — moving from symptom relief toward true restoration of sexual health. While early data is encouraging, especially in men with mild to moderate ED of vascular origin, more rigorous clinical studies are needed to confirm long-term safety and effectiveness.
