Is Your Laptop Cooking Your Testicles? 293

Velcroman1 writes "Whoever invented the 'laptop' probably didn't worry too much about male reproductive health. Turns out, unsurprisingly, that sitting with a computer on your lap will crank up the temperature of your nether regions, which could affect sperm quality. And there is little you can do about it, according to the authors of a study out today in the journal Fertility and Sterility, short of putting your laptop on a desk. 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."

    I agree, only the poor and dumb should reproduce on a massive scale.

    Despite what may seem obvious, it wasn't so much the heat coming from the computer that was doing it. When you think about it, the hot parts of a laptop are a good distance away from your scrotum (or, at least, they should be if you're not doin' it wrong). The researchers found that it was the leg position used to keep the computer on the lap - i.e., legs closed together - that was the source of the problem. Keeping your legs together while seated was the strongest cause in the rise in scrotal temperature, because you're surrounding your nads with warm parts of the body and covering surface area that would help remove heat. The researchers found that keeping your legs apart would mitigate the problem, but only a little, because then you'd need a large laptop pad bridging the gap, which covers your nethers right back up. Or you could get a humongously wide laptop.

    Somehow, I'm thinking that the future of the human race is not imperiled by laptops making men infertile. At least, not in that way.

    And how many young men (and women) are going to be very disappointed when they discover that it's an astonishingly ineffective method of birth control?

    Scotsmen have a solution that should also help with the laptop-caused problem.

    Overpopulation! Are you one of them?

    I agree, only the poor and dumb should reproduce on a massive scale.

    Does that include people dumb enough to rely on a "laptop" computer for birth control?

    I'm a young guy who's settled down, and I still see it as an awesome thing. We don't want kids, and my parents don't want grandkids. Her parents already have grandkids because of her sister, so no pressure from that side either.

    So who do you think is going to look after you when you're eighty? The fucking tooth fairy?

    Oh no, it will be other people's kids and grandkids, aren't you lucky that you won't have to do any of the hard work but still get the same benefit?

    The true class warfare involves the narcissistic socialists against the "poor and dumb".

    As opposed to the fake class warfare of libertarian free-market wage enslavement?

    Evolution at work: on an overpopulated planet, where the world's resources are being squandered faster than they can be replaced and there's barely standing room in most of the more habitable regions, "educated" people defer procreation for a host of reasons.

    Meanwhile, population is increasing out of all control in those areas least able to support it, driven by the fastest pricks and spread legs, each successive generation dumber than the last.

    My wife and I would look after each other until we no longer could, at which point we would put ourselves in a home.

    How would having kids just so they could take care of us be any better? That seems like a real dick move.

    Who is going to staff this "home"? Other 80 and 90 year olds? Or other people's kids and grandkids?

    The grandparent post overstated the case, because of course there's no need for everyone to have their own kids to look after them when they're old. But we still need young people to follow us. So it's perfectly fine for lots of people to choose to be "evolutionary dead ends", as long as not everyon makes that choice. :-)

    I highly, highly recommend that you both buy long-term care insurance. If that's your late-retirement plan, be prepared for it.

    My wife's grandparents worked hard their whole lives and saved nearly everything, but after he died and his pensions + social security cut off, her $4600 a month nursing home bill has been draining their savings at an alarming rate.

    You do not want to rely on Medicare for this. You'll be stuck in a sub-par home because choices for Medicare beds are limited.

In 1869 the waffle iron was invented for people who had wrinkled waffles.
