Better watch your “boys” when using it on your lap..

I wonder if guys out there cringe while reading this.

Men who use laptop computers could be unwittingly damaging their fertility, experts believe.

Balancing it on the lap increases the temperature of the scrotum which is known to have a negative effect on sperm production, researchers found.

Lead researcher Dr Yefim Sheynkin, from the State University of New York at Stony Brook, said: “Laptops can reach internal operating temperatures of over 70?C.

“They are frequently positioned close to the scrotum, and as well as being capable of producing direct local heat, they require the user to sit with his thighs close together to balance the machine, which traps the scrotum between the thighs.”

The researchers asked 29 healthy male volunteers aged between 21 and 35 to take part in an experiment.

They then recorded the temperature changes to the scrotum caused by laptop use and different seating positions over one hour time periods.

Just sitting with the thighs together, a posture needed to balance a laptop, caused scrotal temperatures to rise by 2.1C.

So, did they have a thermometer down there? Wires? How’d they take the temp? Nevermind.
