Erectile dysfunction is a significant reason of decreased quality of life in men. A new study in the February 2009 issue of The Journal of Sexual Medicine suggests that men who make intensive changes in lifestyle are able to improve their erectile function.

A total of 209 subjects were randomly assigned to one of the two treatment groups. The 104 men randomly assigned to the intervention program received detailed advice about how to lose weight, improve their diet, and increase their physical activity. The 105 subjects in the control group were given general information about healthy food choices and advice on increasing their level of physical activity.

The results showed that erectile function improved in the intervention group. Thirty-five of the subjects in the intervention group and 38 subjects in the control group had normal erectile function. After two years, these figures were 58 subjects in the intervention group and 40 subjects in the control group.

There was a strong correlation between the success score and restoration of erectile function.

“This study concludes as we have long held the belief in that you don’t need medications to treat erectile dysfunction,” said San Diego-based Dr. Irwin Goldstein, editor-in-chief of journal and medical director of sexual medicine program at Alvarado Hospital. "By losing weight and increasing exercise, erectile function can improve.”
