“ Although this research all points to a relationship between ED and bicycling, this association has
been demonstrated only recently in a population-based random sample of men.
Researchers evaluated data from the landmark Massachusetts Male Aging
Study (MMAS), a large cross-sectional survey of 1709 free-living men in their 40s to 70s.
The random sample is representative of a similar population of men and includes a variety of cyclists, such as recreational and
occasional riders, stationary bikers, and serious sport cyclists.
This is unique among studies done on ED and bicycling to date,
and it allows the findings to be generalized to the entire population of cyclists.
