Cell Phones Make you Infertile?

Now this is ripe for Jay Leno territory.

Within the study group, those men who did not use mobile phones were
found to have average sperm counts of 86million per millilitre. This dropped to
69 million per millilitre for men with mobile phones who used them less than two
hours a day, 59million per millilitre for usage of two to four hours and
50million per millilitre for more than four hours a day.

I think this researcher may need to do more research rather then just making up the causes of this lowering of the sperm count on the fly.

"The effect of mobile phones on sperm may be due to the electromagnetic
radiation the devices emit or to the heat they generate," Dr Agarwal said
yesterday.

I'm pretty sure these guys are not using the cell phone with their crotches. Well with wireless Bluetooth earphones maybe people in Ohio (where the study was conducted) are doing just that. Perhaps they are storing the phones in their underpants while they talk hands free for some freakish reason. However this guy is probably on the right track:

"People who spend more than four hours a day on their mobile phone are
probably not doing physical work. They're probably sitting down for long periods
of time, which increases heat to the scrotal area, which affects sperm
production," Professor Driscoll said.

If you are on a cell phone for 4 entire hours a day then low sperm count will probably be the very least of your worries.
