Beckham's undies might make you impotent sterile

Though those wonderful Emporio Armani underwear sales are at a record high, the boys over at SbB found that it's not all good news.

Not according to this one Ph.D. guy:

Dr. Allan Pacey, of Sheffield University, said: “David Beckham has had his children, but would-be fathers can’t get away with it.

“Very tight pants damage fertility. The reason you have testicles outside the body is that they stay cooler there.”

So yeah. You're welcome for the 'heads up.'
