Using
shockwave therapy for erectile dysfunction is among one of the newer and less
invasive ways to treat this common sexual challenge. Also known as penile
extracorporeal low-intensity shockwave therapy, this method involves the use of
lower intensity acoustic pulse waves that focus on and break up micro plaque in
the penis, which in turn improves blood flow. The waves also induce the release
of nitric oxide, another process that boosts blood circulation, as well as
stimulates the formation of new blood vessels (neovascularization).
Some scientific studies have suggested that shockwave therapy
for erectile dysfunction may be more effective than oral medications (e.g.,
Viagra, Cialis), penis pumps, and other techniques.
In a
recent (2017) review published in Urology, the authors evaluated
data from 9 studies that involved 637 patients. They reported that low-intensity
extracorporeal shockwave therapy significantly improved both International
Index of Erectile Function (IIEF) and the Erection Hardness Score (EHS). In
addition, each treatment could last at least three months.
In an
earlier study, the authors noted that shockwave therapy was effective in men
who responded to phosphodiesterase 5 inhibitors (PDE5i; e.g., Viagra) and could
also convert men who did not respond to PDE5is to become responders. A
subsequent trial explored the use of shockwave therapy in men who failed to
respond to PDE5is. The 52 men received 3,000 shockwaves once a week for 12
weeks while also continuing use of PDE5is. At the one-month follow-up, 35 of
the 52 men (67.3%) were able to achieve an erection suitable for intercourse.
At three months, 33 of the 35 (94.3%) could still maintain an erection.
Use of
low-intensity extracorporeal shockwave therapy appears to be effective in
treating some men who have erectile dysfunction. Men who fail to respond to
oral ED drugs especially may be helped.
