Bike saddle lower sperm

Few doubt that cycling helps you get healthy. One study last year found cyclists are less likely to develop heart disease or cancer, and a review showed it improves fitness and leads to longer lives. In recent years, scientists have linked cycling with several male health problems, including erectile dysfunction, which they speculate is caused by the saddle decreasing blood flow to the penis. In one study, Norwegian researchers gathered data from men after they took part in a long-distance bike tour. But the researchers admitted their sample was small, that more research was needed, and that their findings did not necessarily mean there was a direct link between cycling and prostate cancer. A study in involving 15 Spanish triathletes found that those with low enough levels of sperm to constitute a fertility problem were cycling more than km every week.

Does cycling really damage men's sexual organs? | Jessica Brown | Environment | The Guardian

By Rob Kemp. In time for the start of the Tour de France, the health editors of the British press warned once again that mankind was cycling towards a childless oblivion. Back in , Dr Irwin Goldstein, an impotence specialist at Boston University, released data suggesting that saddle-soreness was pretty much a precursor to infertility. Since then, the reporting of such studies has followed a well-worn path. In the study, the triathletes tested were found to have less than 10 percent of normal looking sperm most fertile men have around percent.

How Bicycling Affects Male Fertility

The main cause of infertility in males is low sperm count, but other causes such as poor quality sperm, inadequate sperm motility and semen deficiencies can also lead to infertility, according to BabyHopes. Both environmental and physical factors can cause low sperm count, the primary cause of infertility. An infertility study of elite triathletes conducted at the University of Cordoba Medical School in Spain suggested that cyclists are more likely to show signs of abnormal sperm and a low sperm count compared to other athletes, especially for those cyclists who regularly ride longer distances, according to the BBC. Researchers who conducted the study believe the main reason for the apparent connection between cycling and infertility is temperature elevation due to tight clothing, according to the London Sperm Bank Digest.

Surprisingly little data are available on whether bicycling, particularly at moderate levels, has any impact on fertility. Many of the studies available are small and involved elite level athletes. Still, that covers a lot of cyclists in Colorado. Ready to take the next step?
