Study Description
Brief Summary:
Low intensity shockwaves (1/10 the ones used in Lithotripsy) are delivered to the penile tissue. Shockwaves are created by a special generator and are focused using a specially designed shockwave applicator apparatus. The shockwaves are delivered through the applicator covering the corpora cavernosa of the penis. In previous studies the investigators used a medium focused probe and in this study the investigators are evaluating results of this therapy using a wider focus probe in the aim of improving results of treatment.

Condition or disease Intervention/treatment Phase
Erectile Dysfunction Device: Low intensity shock waves Phase 3
