Pulse Wave Therapy for erectile dysfunction uses pulsed sound waves to open old, clogged blood vessels and create new blood vessels, to increase blood flow to the penis. As you get older, the blood vessels that supply blood to your penis begin to collapse or break down. Good blood flow is essential to erectile function. Basically, the acoustic waves of the Pulse Wave Therapy stimulate increased blood flow to the penis by opening existing blood vessels and stimulating the growth of new ones. Increased blood flow results in stronger, harder, and more sustainable erections.
