Shockwave therapy for ED is well established non-invasive medical procedure that has been used for over a quarter of a century to treat a variety of conditions. A shockwave is an intense but very short acoustic energy wave, which travels faster than the speed of sound. Shockwave therapy stimulates the growth of new and better blood vessels when the applied to the penis.
An erection starts in the brain! Sensory or mental stimulation, i.e. sexual arousal, is followed by a burst of a brain chemical called nitric oxide which functions as a neurotransmitter.
Nitric oxide causes the smooth muscle enzyme guanylate cyclase to produce a messenger called cyclic guanine monophosphate (cGMP), which acts to increase the size of blood vessels carrying blood to the penis, and decrease the size of vessels carrying the blood out. Thus making the penis erect.
