Who knew? Your car's seat warmer cooks and kills sperm

It's still pretty summery in most places but soon enough fall and winter will be here, which means instead of cranking the A/C on your way to work you'll be hitting the seat-warmer switch.

Or maybe you'll want to think twice about that...

A recent study in Germany found that the heated seats found in more and more vehicles as a luxury option are not only heating people's chilly bums but they're also essentially cooking men's privates and causing them to have significantly lower sperm counts.

Of course this is really only an issue for guys who are trying to have a baby, in which case experts recommend wearing loose undies, making frequent stops on long trips, and trying to use the heated seats as little as possible.
