"This is the largest comparative study to date, exploring the associations of cycling, bike and road characteristics with sexual and urinary function using validated questionnaires," explained lead investigator Benjamin Breyer, MD, MAS, of the Department of Urology, University of California-San Francisco.
"We believe the results will be encouraging for cyclists. Cycling provides tremendous cardiovascular benefits and is low impact on joints. We believe the health benefits enjoyed by cyclists who ride safely will far out weight health risks."
Studies - Affects - Function - Hypothesis - Impact
Some studies have suggested that cycling negatively affects erectile function. The hypothesis was that this negative impact is caused by the prolonged perineal pressure and micro-trauma during cycling. However, these studies lacked the use of validated measures or comparison groups, and were limited by small sample sizes.
In this multinational study a cross-section of three athletic groups -- cyclists, swimmers, and runners -- was surveyed using Facebook ads and outreach to sporting clubs for athletes. Participants included 2,774 cyclists, 539 swimmers, and 789 runners. Participants completed validated questionnaires, including the Sexual Health Inventory for Men (SHIM), International Prostate Symptom Score (I-PSS), and National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), as well as questions about urinary tract infections (UTIs), urethral strictures, genital numbness, and saddle sores.
Addition - Comparisons - Activities - Pressure - Researchers
In addition to the comparisons between similar athletic activities with and without perineal pressure, the researchers examined how cycling intensity, bicycle configuration, and even...
