Spanish researchers have found a direct link between men who do intensive cycling tra
Being fat and obese also reduces the probability of fatherhood as well....

Men who cycle more than 186 miles a week face fertility risk
By Daily Mail Reporter
Last updated at 8:31 PM on 29th June 2009
Spending too long in the saddle could affect a man’s chances of fatherhood.
Cycling for long distances greatly reduces sperm quality and raises the risk of fertility
problems, a study has revealed.
It found that just 4 per cent of the sperm of athletes pedalling 185 miles a week – around 25 miles a day – were a normal, ‘healthy’ shape.
In the most fertile men, the figure was up to 20 per cent. It said that saddle friction and tight, hot clothing could be to blame, while the position a man sits in could affect blood flow.
This stress on the body results in an abnormal increase in special molecules which in turn alter sperm quality.
Professor Diana Vaamonde, of Spain’s Cordoba University Medical School, told the
European Society of Human Reproduction and Embryology’s conference in Amsterdam that, even though the men tested were professional triathletes, anyone who cycles could be at risk.
She said: 'We believe all the factors inherent in this sports activity, especially with regards to the cycling part, may affect sperm quality.
'Protective measures for these sportsmen need to be developed. These could include giving antioxidants and modifying training regimes.
'Or we could take preventative measures by freezing athletes’ sperm.'

Now you know why it's such a popular sport for old farts.
And, why there's so much regret among men with bratty children that they ddn't start riding sooner...

Funny though, today they posted a link that states that having sex daily improves sperm quality. So - ride as much as you want, and have sex daily. Problem solved.

You sure it's not opposite? It creates a fertile man ....
At the point in my life when I was riding the most (well .. 2nd most, almost) my wife and I conceived our son. We were told she'd need to undergo fertility treatment to have a child (and I'm thinking oh great ... Jon+Kate+8 ...).
Either way. Riding worked for me

Um. The subjects were all triathletes. How did they rule out swimming and running as potential causes?

I spoke with an OB regarding this last year when my wife and I were ready to start trying. She said I could stay off the bike 72 hours before each attempt to guarantee the largest swim team, but it wasn't a big concern. I took a test and there was definitely more than a 4% retention rate (granted, I ride about 125 miles per week). She also pointed out that a man out of shape from lack of exercise will produce less sperm in the first place.
