Not All Shockwaves Are Created Equal

We use the Storz DUOTLITH® SD1 T-Top Ultra which produces focused shockwaves.  For the sake of simplicity, there are focused shockwaves and radial shockwaves. It is important that you know the difference when making an informed decision about your health.  

Radial Shockwaves

Radial pressure waves act similar to sound waves and have a lower peak pressure and rapid outward propagation. This limits the effective depth of penetration to 35 mm.


Radial wave generating devices are classified as “class 1 medical devices” by the FDA. This means that “professionals” are not required to have additional training prior to offering the therapy to patients and there is limited regulatory oversight.

Focused Shockwaves

Focused shockwaves (sometimes called linear waves) have a distinct focal point and a greater depth of penetration.  Focused shockwave devices are considered “class 2 medical devices” and require FDA approval to ensure safety and treatment efficacy.  They also must be purchased and operated under the license of an approved medical provider.

Focused Shockwaves

Radial Shockwaves

"Currently, the majority of providers in the United States who are offering shockwave therapy outside of a rigorous research protocol, ... are using radial-wave technology (i.e., class 1 medical device), whereas the true clinical benefit may lie in the application of linear-wave (focused wave) technologies (i.e., class 2 medical device)."

"Linear ultrasound probes (as opposed to radial) should be considered standard of care. They are the only probes that have been consistently shown to benefit patients based on the available literature, although in practice radial shockwave probes are commonplace."

"No quality evidence was found to support the use of radial waves in humans for the treatment of erectile dysfunction. In animal models and at the cellular level, the results are contradictory. More research is needed." 

Sandoval-Salinas C, Saffon JP, Corredor HA, et al. Are Radial Pressure Waves Effective in Treating Erectile Dysfunction? A Systematic Review of Preclinical and Clinical Studies. Sex Med 2021;9:100393.

Personal hypothesis: Focused shockwaves have enough power and focus to break up existing calcified arteries that are failing during attempted erection.  

More studies need to be done before I would charge for radial shockwave therapy for ED so I opt for more powerful, more regulated, and more expensive equipment.

What is

Extracorporeal shockwave therapy (ESWT) is a non-invasive therapeutic approach that uses acoustic waves to break down tissue or to promote healing and repair.  It was developed during the 1960’s and 1970’s.  It gained wide acceptance in the 1980’s as a non-invasive way to break up kidney stones.  During the 1990’s to 2000’s it was adapted to address several musculoskeletal issues such as tendinopathies and bone disorders.  It has since been adapted to treat erectile dysfunction (ED) as well as coronary artery disease.

How does Li-ESWT help ED?

Low-energy extracorporeal shock wave therapy for promotion of vascular endothelial growth factor expression and angiogenesis and improvement of locomotor and sensory functions after spinal cord injury.

Shockwave therapy works by triggering the body’s innate healing mechanisms to stimulate the growth and development of new blood vessels in the penis. Research has shown that shockwaves induce the release of vascular endothelial growth factor (VEGF) and nitrous oxide (NO) which signal to the body to make new blood vessels and repair old ones.  It also breaks up calcium deposits in damaged arteries. These new, healthy blood vessels are responsible for the development and sustaining of an erection. Therefore, it addressed the underlying problem of ED.  It is so effective that it is being adopted as an alternative to treat coronal artery disease in place of surgery.

Does Li-ESWT really regenerate blood vessels?

Extracorporeal Shockwave Therapy for erectile dysfunction has not been studied as thoroughly as it has been for other conditions.  However, research has repeatedly demonstrated that extracorporeal shockwave therapy stimulates the production of new blood vessels through the release of vascular endothelial growth factor (VEGF) and nitrous oxide production (NO).

What results can I expect from Li-ESWT?

European urology, 71(2), 223-233. 2) Sokolakis, I., & Hatzichristodoulou, G. (2019). Clinical studies on low intensity extracorporeal shockwave therapy for erectile dysfunction: a systematic review and meta-analysis of randomised controlled trials. International journal of impotence research, 31(3), 177-194.

Results will vary based on the existing underlying medical conditions that affect the blood vessels of the penis.  For research purposes, subjective results are measured using the International Index of Erectile Function (IIEF) and Erection Hardness Score (EHS) to measure the strength of an erection.  Objective results are obtained by measuring the increase in blood flow to penile blood vessels before and after treatment as measured by doppler ultrasound.  


A 2017 literature review of 14 studies (seven of which were randomized controlled trials), including 833 patients, “suggests that Low-Intensity Extracorporeal Shockwave Therapy could significantly improve the International Index of Erectile Function (IIEF) and Erection Hardness Score (EHS) of erectile dysfunction patients. … There was evidence that these men experienced improvements in their erectile dysfunction following Low-Intensity Extracorporeal Shockwave Therapy.” 1

A 2019 literature review of ten randomized controlled trials including 873 patients “showed that low-intensity extracorporeal shockwave therapy (LI-ESWT) could significantly improve erectile function in men with ED regarding both patient-subjective outcomes (IIEF-EF and EHS) and patient-objective outcomes (blood flow measurements of penile blood vessels). In conclusion, the present meta-analysis provided results showing that LI-ESWT significantly improves erectile function in patients with vasculogenic ED.” 2

What do the critics say?

1) Young Academic Urologists Men's Health Group. Low-intensity shockwave therapy for erectile dysfunction: is the evidence strong enough?. Nat Rev Urol 14, 593–606 (2017).

We believe that individuals should be empowered with all the unbiased evidence for and against any medical treatment so they can make an informed decision regarding their own health. 

The following is an excerpt from a medical journal that fairly looks at both sides of the evidence (or lack thereof) regarding Li-ESWT for ED:

"Single-arm trials almost unanimously show beneficial effects in patients with vasculogenic ED, even in those who do not respond to phosphodiesterase-5 inhibitors."

"Randomized controlled trials (RCTs) have produced conflicting results, and have evaluated erectile function only a short time after treatment; several RCTs are highly biased."

"Meta-analyses and systematic reviews conclude that shockwave therapy has an effect, but these analyses are limited by the fact that biased RCTs have been included in these analyses, and some fail to recognize this limitation."


"Thus, no high-quality level 1a evidence is available and level 1b evidence is conflicting regarding the use of Li-ESWT for ED treatment."1

How many treatment sessions are required?

There is no official consensus from the American Urological Association on this subject.  We follow the protocol published in the World Journal of Men’s Health, April 2020, which consists of a total of 12 treatments.  Two treatments every week for 3 weeks, a 3-week resting period, followed by another 3 weeks of treatments.

What settings do you use?

There is no official consensus from the American Urological Association on this subject.  A 2022 review of 16 randomized controlled trials including 1,064 participants concluded that “treatment plans with an energy density of 0.09 mJ/mm2 and pulses number of 1,500 to 2,000 are more beneficial to IIEF in ED patients.”  We follow those guidelines.

Is Li-ESWT safe?

Treatment of erectile dysfunction uses low intensity shockwaves to break up calcified arteries and stimulate the release of vascular endothelial growth factor (VEGF) and nitrous oxide (NO).  It is not a high intensity shockwave used to break up kidney stones.  It is non-invasive and is done without any anesthesia.  Side effects are generally limited to mild redness, swelling or occasional bruising which is temporary.

What about in-home shockwave devices?

Devices marketed for in-home use are Class I medical devices and produce a radial shockwave rather than a focused shockwave.  The clinical studies showing positive results from shockwave therapy for ED all use focused shockwaves and not radial shockwaves.  Focused shockwaves carry up to 100 times more pressure than radial shockwaves.  A certain threshold of energy is required to stimulate blood vessel repair and regrowth. In-home treatments are underpowered.  Using them is like trying to boil an egg in a bathtub. No amount of time is sufficient to achieve the desired result.  Since they are class 1 medical devices, they are exempt from the FDA from having to provide information regarding the energy parameters of their device so it is unknown how much pressure is being generated during treatment.

A focused shockwave carries between 10 - 100 MPa of pressure.  In contrast, a radial shockwave only carries between  0.1 - 1.0 MPa of pressure.

Is Li-ESWT FDA approved to treat ED?

Low-Intensity Extracorporeal Shockwave is not yet approved by the FDA for the treatment of ED.  This makes its application to ED an off-label use. In medical practice “off-label use is common, accounting for approximately 10% to 20% of prescriptions.”  The American Urological Association considers low-intensity extracorporeal shock wave therapy investigational treatment options.
