"I think it's a legitimate question," says Dr. Martin Resnick, chair of the department of urology at Case Western Reserve University in Cleveland, Ohio. "But more data need to be presented." There may also be other factors, such as the fit of the bike and your own individual anatomy and riding style...
Further evidence of a possible link is reported this week in the Journal of Andrology. The admittedly small study examined 17 police officers on bike patrol and compared the pressure on various parts of their saddles with the number and duration of their erections during sleep. Those who cycled the most and were subjected to the greatest perineal pressure had the fewest and shortest erections. "The bicycle seat nose appears to be the biggest problem," says the study's lead author, Steven Schrader, a reproductive physiologist at the National Institute for Occupational Safety and Health...
...Even if bike seats do cause problems, the solution is not necessarily clear. Goldstein is adamant that the saddle nose should be eliminated. And yet, says Dr. Roger Minkow, a physician who designs bike seats and other accessories for a living, that would make controlling a bicycle more difficult.

Or try switching to a recumbent bike. Whatever you do, don't dismiss genital numbness. Your body could be trying to tell you something important...
