Dr. Schwartzwald is skilled at the medical treatment of erectile dysfunction, correction of abnormal penile curvature, and the treatment of Peyronie's disease. Although he is an advocate for all of the advances in the treatment of ED, including oral medications such as Viagra, Levitra, and Cialis, Dr. Schwartzwald is also very active in the surgical correction of erectile dysfunction. His delicate technique places an internal pump into an easily accessible, inconspicuous position in the scrotum. By using the "invisible" pump, in less than one minute, sterile saline solution is cycled into the penis giving back normal function and enhanced endurance.
