Boston, To maintain the respiratory and circulatory health, cycling is a sport that is very good. But do not overdo it because men are cycling (gowes) more than 5 hours a week have lower sperm counts.

Relationships with the cycling sport sperm quality in men has long been a topic of conversation. However, studies that measure how much the link between the two was revealed in research from Boston University Lauren Wise recently.

Research involving 2200 participants were men who visited a fertility clinic was conducted by observing sperm samples respectively. In addition, participants were also asked to fill out a questionnaire about sports activities are done daily.

After adjusting for other factors such as weight loss and health conditions, researchers reveal a man who rarely exercise has a sperm count lower than they exercise regularly. Sperm produced also worse quality because of less active.

Interestingly, some men who diligently exercise was also experiencing similar problems. But only certain types of sport that makes men experience decreased quality and quantity of sperm, the cycling sport.

Cycling more than 5 hours a week making 31-40 percent of men have sperm counts below normal. This figure is even higher than in men who never exercise that is 23-27 percent.

Researchers suspect the trigger is trauma that occurs in the vicinity of the fruit of charity due to friction with the bicycle saddle. In addition, the increase temperature in the area are also believed to be one of the factors that influence the production of sperm.

However researchers admit the respondents involved do not necessarily represent the male population in general. Because the participants are visitor fertility clinic, it could be since the beginning of these men already have a problem with his sperm.

“It takes further studies to see whether consistent results before concluding the existence of causation,” said the researchers, Lauren ,Friday (12/10/2010).
