Over the last several years, NIOSH researchers have investigated the potential health effects of prolonged bicycling in police bicycle patrol units, including the possibility that some bicycle saddles exert excessive pressure on the urogenital area of cyclists, restricting blood flow to the genitals, resulting in adverse effects on sexual function.
NIOSH worked with several police departments with bicycle patrols to conduct reproductive health research. In these studies NIOSH did more than assess a problem; it also tested a solution and published recommendations. Several bicycle saddle manufacturers have developed saddles without protruding noses. NIOSH has investigated whether these saddles, which remove the pressure from the urogenital area, will alleviate any potential health problems.
