According to a new study published in Fertility and Sterility Journal, putting a laptop on your lap will crank up the temperature of the scrotum, which could affect fertility. Reuters Health quotes an author of the study:
Millions and millions of men are using laptops now, especially those in the reproductive age range," said Dr. Yefim Sheynkin, a urologist at the State University of New York at Stony Brook, who led the new study. Within 10 or 15 minutes their scrotal temperature is already above what we consider safe, but they don't feel it," he added.
The reason men have scrotums is to keep the testicles at a cooler temperature, so parking a hot computer on their lap is defeating the purpose.
Under normal circumstances, the testicles' position outside of the body makes sure they stay a few degrees cooler than the inside of the body, which is necessary for sperm production. I wouldn't say that if someone starts to use laptops they will become infertile," Sheynkin told Reuters Health. But frequent use might contribute to reproductive problems, he said, because "the scrotum doesn't have time to cool down."
Interestingly, even people who used lap pads did not make a difference, because people would keep their knees together, limiting air circulation. More at MSNBC
Last year Kimberley rounded up a few laptop pillows and it is true, they do kind of force your knees together.
