Lifestyle management of erectile dysfunction: the role of cardiovascular and concomitant risk factors.

The influence and significance of lifestyle factors in erectile dysfunction (ED) have been demonstrated in cross-sectional and prospective, randomized, controlled trials. Recent epidemiologic studies in several countries have shown that modifiable lifestyle or risk factors, including physical activity in particular, are directly related to the occurrence of ED. In this article, we review several recent observational studies, 2 of which include a longitudinal follow-up component in the study design. The levels of physical activity in both of these studies predicted ED prevalence and incidence. Furthermore, the role of lifestyle changes (weight loss, physical activity) were recently demonstrated to be effective in modifying ED in a prospective, randomized Italian trial in moderately obese, sedentary men. Men without overt diabetes mellitus or cardiovascular disease participated in this landmark study. Other studies have shown that aggressive management of cardiovascular risk factors can increase the effectiveness or outcomes associated with pharmacologic management of ED. Taken together, these studies support the value of risk factor modification and lifestyle change in the clinical management in men with ED and concomitant cardiovascular illness.
