Researchers at Boston University just published a study that may lead men biking regularly to some troubled thoughts: Biking more than 5 hours per week may damage their sperms.
Only Biking Hurts
The study examined data gathered from in-vitro fertilization clinics between 1993 and 2003. 2261 participants filled out a questionnaire that indicated their general lifestyle and what physical activities they took part in. Finally, semen samples were taken.
Out of all activties the men listed, only riding a bike for more than 5 hours per week caused problems in the form of sperm count and sperm mobility. Men involved in other, even “vigorous”, physical activities had the same readings as those that never exercised.
Dr Lauren Wise, who headed the study, told Reuters that one explanation of the results may be trauma or temperature increase in the scrotum, but also noted that it is still too early to draw firm conclusions between biking and sperm health.
Have you ever had problems with your reproductive organs that you could track back to biking?
