Laptops and Infertility, Vital Information!

Does Laptops have anything to do with infertility?! You may wonder what a question, dont’ you? Latest research tells something in this regard.
The problem is not with the laptops but with the way one sit while operating laptops. Yes, your sitting posture may cause problems! If guys can find a way to operate laptop computers with their legs apart, they might limit their risk of infertility, the new study finds. Keeping the legs splayed while using a laptop generated substantially less damaging heat in the scrotum than keeping legs together. Putting a shield under the laptop didn’t seem to help beat the heat.
The testes generally are 2 to 4 degrees Celsius cooler than standard body temperature, a unique environment conducive to the rapidly dividing nature of sperm cells. Heating the area can trigger oxidative stress, slow the motion of sperm and lessen their ability to fertilize an egg for weeks or months, says Edmund Sabanegh, a urologist at the Cleveland Clinic in Ohio.

In the new study, urologist Yefim Sheynkin of Stony Brook University in New York and his colleagues enlisted 29 men ages 21 to 35 to participate in three tests in which each man operated a laptop computer on his thighs for one hour. One test entailed keeping the thighs together while using the machine. A second required the same position, but with a padded shield placed under the laptop. The third test allowed the men to keep their legs apart at a 70-degree angle as they used a laptop. Each of the men completed all three tests, but did only one test per day. Before each experiment, sensors recorded the scrotum temperature of each volunteer and recorded any changes during the session.
All three uses of a laptop increased the men’s scrotal temperature substantially from pretest levels, but keeping the legs splayed limited this increase to about 1.4 degrees C during the hour-long test. When the legs were kept together the temperature rose by 2.2 degrees with a shield and 2.3 degrees without one.
What’s more, it took an average of 28 minutes for scrotal temperatures to rise 1 degree C when the men had their legs apart, but only 14 minutes to increase that much when they kept their legs together with a shield and 11 minutes with legs together and no shield.
That means stop putting laptops on your lap, stop using hot tubs and other things of that nature. But just keeps your legs apart and use laptops, that’s it.
