This study indicates that the pressure between the biking officer and the bicycle seat is related to numbness in the genitals and subclinical impairment of erectile function. Blood hormone levels and semen quality were normal in the officers providing samples. Recommendations to minimize or eliminate these specific problems reported by biking officers include minimizing pressure to the perineum from the bicycle seat nose. This can be achieved by taking rest periods off of the bicycle saddle and enuring proper bicycle fit. The police department is encouraged to investigate the feasibility of using bicycle seats without a nose or other extension.
