From 1999 to 2004, there had been 21 publications from multiple medical specialties (sexual medicine, urology, neurology, cardiology, biomedical engineering, sports medicine, emergency medicine, and officials from the National Institute for Safety and Occupational Health) investigating the relationship between bicycle riding and erectile dysfunction (ED). In the previous 18 years, there have been 14 such studies.
The primary aim was to summarize accumulating data on the safety of bicycle riding based on medical evidence categorized by levels of evidence, including case reports, observational studies, case control studies, mechanistic studies, and population-based epidemiologic investigations. The secondary aim was to address the concerns of bicyclists and propose measures to minimize the risk of ED associated with bicycle riding.
An English-language medical literature review was made of publications in peer review journals from 1981 to 2004, including published abstract presentations at major medical meetings.
