  Purpose

Healthy lifestyle factors are associated with maintenance of erectile function in men. To determine the effect of weight loss and increased physical activity on erectile and endothelial functions in obese men.

Randomized, single-blind trial of 110 obese men without diabetes, hypertension, or hyperlipidemia, who had erectile dysfunction that was determined by having a score of 21 or less on the International Index of Erectile Function (IIEF).

The 55 men randomly assigned to the intervention group received detailed advice about how to achieve a loss of 10% or more in their total body weight by reducing caloric intake and increasing their level of physical activity. Men in the control group (n = 55) were given general information about healthy food choices and exercise.
