According to the Massachusetts Male Aging study, the prevalence of erectile dysfunction is 52%. An erection occurs when there is an integration of vascular, psychological, hormonal, neurologic, and anatomical systems. Age and chronic diseases could compromise the function of any of these systems, resulting in ED. The goal is to improve blood flow and promote the growth of healthy connective tissue. With non-invasive and minimally invasive procedures, improvement of ED in selected patients is possible.
