Using an experimental bicycle seat to reduce perineal numbness

Phys Sportsmed. 2002 May;30(5):27-44. doi: 10.3810/psm.2002.05.283.

Abstract

Researchers evaluated the effectiveness of an experimental seat that was designed to prevent perineal numbness and possibly erectile dysfunction in male bicyclists. A trial of the device among 15 experienced cyclists measured perineal sensation after a 1-hour stationary cycling session on a standard seat followed several days later by the same exercise protocol on the experimental bike seat. Cyclists reported more numbness with the standard seat than with the experimental seat (79% vs 14%). Sensory testing found greater hypoesthesia with the standard seat. Innovations in bicycle seat design may decrease or eliminate perineal numbness.
