Today's Times says "scientists have linked portable computers and male infertility":
"Businessmen and teenage boys could be risking their fertility by using laptop computers, research suggests."
"The combination of heat generated by the computers and the posture needed to balance the equipment on the lap leads to raised temperatures around the scrotum, a study has found. Past research shows that higher scrotal temperatures scan damage sperm and affect fertility."
Looks like it's time to put those computers away, boys.
Or at least wear heatproof trousers.
Update: Wouldn't you know it, but in today's Guardian, James Meikle covers the same story... Sheesh, that's what happens when you're out of the office for the morning and don't get a chance to read the paper.
