Hitting the gym may help men avoid diet-induced erectile dysfunction

blood flow and produces an erection. The researchers also examined the rats' coronary arteries to see how they too responded to agents that would relax them and maintain blood flow to the heart, an indicator of heart health.

Results

The findings showed that rats who ate the Western diet but stayed sedentary developed erectile dysfunction and poorly relaxing coronary arteries. However, those who ate the diet but exercised were able to stave off these problems.

Animals who ate the healthy chow were largely able to avoid both erectile dysfunction and coronary artery dysfunction.

Importance of the Findings

These findings may suggest that exercise could be a potent tool for fighting the adverse effects of the Western diet as long as the subjects remained very active over the course of consuming this type of diet, the authors say. Whether exercise would still be effective in reversing any vascular problems after a lifetime of consuming a Western diet is still unknown.

"The finding that exercise prevents Western diet-associated erectile dysfunction and coronary artery disease progression translates to an intensively active lifestyle throughout the duration of the 'junk food' diet," the authors say. "It remains to be seen if a moderately active lifestyle, or an active lifestyle initiated after a prolonged duration of a sedentary lifestyle combined with a 'junk food' diet is effective at reversing functional impairment."
