"Attention guys: it might be time to switch to the iPad. The future of your children could depend on it. The authors of a study that appeared in the journal Fertility and Sterility this month found that men who balanced a laptop on their nether regions could be putting their ability to reproduce at risk, because the computers heated their scrotums to unsafe temperatures.In the study, researchers hooked thermometers to the scrotums of 29 men while they balanced a laptop on their knees. Even with a pad under the computer, researchers found the men's testicles overheated quickly, Reuters reported. "Within 10 or 15 minutes their scrotal temperature is already above what we consider safe, but they don't feel it," said Dr. Yefim Sheynkin, a urologist at the State University of New York at Stony Brook, who led the study. Sheynkin stressed the test's results do not prove that laptop use impacts men's fertility. But previous tests have shown that heating the scrotum even slightly is enough to damage sperm. The researchers found the temperature of the men's testicles rose by up to 2.5 degrees Celsius after working with the computer positioned on their legs. "I wouldn't say that if someone starts to use laptops they will become infertile," Sheynkin told Reuters. But frequent use could cause problems, he said, because "the scrotum doesn't have time to cool down." If found to affect fertility, laptops would join a roster of lifestyle factors like diet, drug use, exercise habits and nutrition that men should monitor in order to keep their reproductive systems healthy. Personal style, though, is not a threat. Sheynkin said that tight-fitting jeans and brief-style underwear did not put men at risk for low sperm counts."

new contraceptive method. "No hunny I don't need to wear a condom anymore. I have been doing my work in my lap."

hasnt this study been done dozens of times over the years

11/7/2010 8:24:22 PM

yes

11/7/2010 8:24:47 PM

^I thought that too.

I was just about to make a thread 15 minutes ago about how putting a computer on my lap actually did kind of hurt it in a very subtle way

Quote :

"An experimental male contraceptive method involves heating the testicles so that they cannot produce sperm. Sperm are best produced at a temperature slightly below body temperature. The muscles around a male's scrotum involuntarily tighten if the man's body temperature drops, and they loosen, allowing the testes to hang, if the body temperature rises. This is the body's way of keeping the sperm at an ideal temperature. Limited research has shown that raising the temperature of the scrotum above body temperature, even for short periods of time, can affect fertility for months."

Laptops are horrible for your nut sack. They are also bad for your face.

old as laptops balls.

i always put a sofa cushion on my lap and then the laptop on top of it.

not for fertility reasons, though, but because it just makes it tons more comfortable and raises the laptop closer to eye-level as well.

Why do you think I play Minecraft?

11/8/2010 9:07:23 AM

So as I sit here in my truck with my nuts resting on my heated seats I'm at risk?

11/8/2010 9:22:32 AM

the ancient Greeks used something similar as a form of contraception

men would teabag a big heated stone

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
