A number of studies have suggested that physically active men have lower rates of erectile dysfunction than couch potatoes, but all of them relied on people being honest about the amount they exercised. A new study published by the Journal of Sexual Medicine checked those results by measuring how much their subjects actually moved.
As part of the National Health and Nutrition Examination Survey in 2003 and 2004, 692 men between the ages of 50 and 85 were fitted out with motion trackers for up to a week and asked to report, among other data, their erectile function over that time period.
The study found a strong correlation between the time men spent moving and erectile function: for every additional 30 min each day the men spent in moderate-to-vigorous physical activity, their odds of developing erectile dysfunction dropped 43 percent.
