Serious Riders, Your Bicycle Seat May Affect Your Love Life - New York Times
The link between bicycle saddles and impotence first received public attention in 1997 when a Boston urologist, Dr. Irwin Goldstein, who had studied the problem, asserted that "there are only two kinds of male cyclists - those who are impotent and those who will be impotent."
Great. Just as I was congratulating myself on the health benefits of my new bicycle, the New York Times tells me too much bike riding leads to impotence. Then again, avoiding bicycle induced erectile dysfunction won't help me much if I keel over young from a heart attack.
