Heated seats can be just what the doctor ordered in the middle of winter, but if you're trying to pass on your car-loving gene pool, you may be better off freezing. Scientists studying male fertility have discovered that the proliferation of heated seats raises the temperature of your junk by a full degree Fahrenheit verses sitting in the car without artificially warmed seats. That's enough to cut your chances of reproducing, and it makes us strategically point a fan at close range just thinking about it. Even without electronically warmed seat bottoms, guys that sit in the car for long periods of time raise the temperature of their man parts by a couple degrees above optimal sperm-making levels. Hmmm, just typing "above optimal sperm-making levels" makes us a bit queasy. The cure? Turn off the heated seats, wear boxers, and don't sit in the car for too long at once. OK... lets talk about something else.
