Previous studies have demonstrated that male professional cyclists often have reduced sperm quality and semen quality. The latest research shows that this risk can occur even for men who ride normally.

The Daily Mail reported that a group of Boston University scientists conducted an experiment with 2,200 men. These men were asked to answer a questionnaire about their exercise routine. Scientists also took samples of their sperm.

According to the analysis of scientists, sperm count and semen quality of men who exercise regularly are not much different from men who never exercise.

However, when analyzing data based on motor sport, the team found that men who were habitually cycling for at least 5 hours per week were at risk of double the amount and quality of sperm. times compared to men who never ride a bike.

Dr. Lauren Wise, the head of the study, explained: ' The reason that men who frequently ride a bike with reduced sperm count may be due to cycling, causing their testicles to rub and raise heat degree. This weakens the sperm and reduces the fertility of the testicles. '

Even so, Dr. Lauren Wise said that more extensive research is needed before there are official conclusions about the relationship between cycling and sperm decline in men. .
