Do mountain bikers have a higher risk of scrotal disorders than on-road cyclists?

Objective: To sonographically investigate whether mountain bikers have a higher prevalence of scrotal abnormalities compared with on-road cyclists.

Design: We studied 85 male mountain bikers (mean age: 25 years; range 17-45 years) and 50 male on-road cyclists (mean age: 23 years, range 15-46 years) with regard to scrotal findings on ultrasound (US).

Setting: Medical University Innsbruck, Austria.
