Scientists warn of sterility after testing temperatures of nether regions Source: Reuters Whoever invented the 'laptop' probably didn't worry too much about male reproductive health. Turns out that sitting with a computer on your lap will crank up the temperature of your nether regions, which could affect sperm quality… The researchers hooked thermometers to the scrotums of 29 young men who were balancing a laptop on their knees. They found that even with a lap pad under the computer, the men's scrotums overheated quickly. "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. So far, no studies have actually tested how laptops impact men's fertility, said Sheynkin, and there is no bulletproof evidence that it would. But earlier research has shown that warming the scrotum more than one degree Celsius (1.8 degrees Fahrenheit) is enough to damage sperm. …………………However, Sheynkin said tight jeans and briefs are generally not considered a risk factor. "Clothes should not significantly change scrotal temperature, because you are moving around," he said. To hold a laptop on your knees, however, you need to sit still with your legs closed. After one hour in this position, the researchers found that men's testicle temperature had risen by up to 2.5 C. A lap pad kept the computer cool and also made sure less heat was transmitted to the skin. But it didn't do much to cool the testicles, and might give "a false sense of security," according to Sheynkin. ………..they could keep their testicles cooler. But it still took less than 30 minutes before they began overheating. "No matter what you do, even with the legs spread wide apart, the temperature is still going to be higher than what we call safe," said Sheynkin. ………"When interested in maximizing fertility potential," he advised, "minimize harmful exposures, eat a healthy diet and exercise regularly haya mambo hayo: Wanaume mnaopenda kuweka laptop zenu mapajani muwe waangalifu.
