Whether cycling has a negative impact on a man’s sexual health and/or urinary function has been the subject of several studies over the years. But now new research suggests that the sexual and urinary health of cyclists is comparable to that of runners and swimmers, and that the benefits of cycling “far outweigh the risks.” According to the authors of the new research, previous studies that looked at how cycling affects men’s sexual and urinary health lacked comparison groups. Benjamin Breyer, lead investigator from the University of California-San Francisco's urology department, said: "Cycling provides tremendous cardiovascular benefits and is low impact on joints. "The health benefits enjoyed by cyclists who ride safely will far out weight health risks." However, the study did show that cyclists had a greater chance of experiencing genital numbness, but that this could be significantly reduced by standing up while cycling for more than 20% of the time. The researchers are now interested in planning future work that looks at whether genital numbness is a possible predictor for future health problems.
