Cycling doesn't damage men's sexual or urinary functions

Scientists find male cyclists are not more prone to sexual or urinary problems than other athletes

In a study that compared cyclists sexual and urinary function to those of runners and swimmers, scientists found that cyclists were no more likely to suffer problems.

In the past previous 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.

"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 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."

The researchers also examined how cycling intensity, bicycle configuration, and even road conditions might impact sexual and urinary functions.

Cyclists were asked about their bike type, saddle type, saddle angle, frequency of wearing padded shorts while cycling, percent of time standing out of the saddle, handlebar height, and the type of surface on which they usually ride.

The scientists that, when compared to swimmers and runners, cyclists' sexual and urinary health was comparable, although some cyclists were more prone to urethral strictures. Interestingly, high intensity cyclists had overall better erectile function scores than low intensity cyclists.

 Standing more than 20 percent of the time while cycling significantly reduced the odds of genital numbness. Adjusting handlebar height lower than the saddle height did increase the likelihood of genital numbness and saddle sores.

"The comparison across athletes sampled in a similar way with validated instruments is what this study adds to the literature," said Dr. Breyer. "We're looking more closely at those who reported numbness to see if this is a predictor for future problems."
