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.
