A study by Dr. Steven Schrader of the National Institute for Occupational Safety and Health in Cincinnati and others concluded that the "nose" of a bicycle seat was implicated in "penile numbness" and erectile dysfunction in bicycle cops. It's been a decade since I was a regular cyclist, but I'm here to tell you that the "perineal discomfort" of a bike seat was no fun at all.
“For the first time, we have a prospective study of healthy policemen riding bikes on the job, using wider, no-nose bike saddles for 6 months. Not only did their sensation improve, their erectile function also improved. Changing saddles changed physiology. This is a landmark study for our field that that is important for future riders, and modification of lifestyle showing improvement without any active treatment.”No-nose Bicycle Saddles Improve Penile Sensation And Erectile Function In Bicycling Police Officers
