    Exclamation Laptops and Sperm Count

    from Wired News

    Men who regularly balance their laptop computers on their laps when working may be jeopardizing their ability to have children, according to a new study from fertility researchers at the State University of New York at Stony Brook.

    The potential risk comes from the heat generated by the laptop computer and the close position of one's thighs when balancing the computer on one's lap, the researchers found. This heat is transferred to the scrotum, where the temperature can rise several degrees, putting users within the danger zone for testicular dysfunction.

    The findings suggest that young men should place laptop computers on a desk, a table or anywhere else but their own laps.

    "I definitely recommend that teenage boys and young males limit the use of laptop computers because the results may be unpredictable," said lead researcher Yefim Sheynkin, director of male infertility and microsurgery at the university. "Don't get me wrong -- the laptop computer is very useful and helpful. But we need to be cautious."

    Scientists have known for years that an increase of even 1 degree Celsius in testicular or scrotal temperature can decrease the production of healthy sperm by as much as 40 percent. In the Stony Brook study, researchers found that test subjects who sat for an hour with running laptops on their laps had a median increase in scrotal temperature of 2.6 to 2.8 degrees Celsius.

    The 29 volunteers, aged 21 to 35, were also asked to sit with their thighs together for an hour without a laptop. This resulted in a median increase in scrotal temperature of 2.1 degrees, suggesting that the act of balancing a laptop computer is just as much to blame as the heat generated by it.

    Two unidentified brands of Pentium 4 laptops were used at random in the study. Additionally, the volunteers were required to wear the same type of clothing in both tests to rule out variations caused by differences in underwear and pants. The volunteers' scrotal temperatures were measured every several minutes with a device attached to both sides of subjects' scrotums.

    The tests did not measure the volunteers' actual sperm production.

    Because of this, laptop users may want to wait for further studies before deciding to change their computing habits, cautioned Moshe Wald, a male infertility specialist in the University of Iowa's urology department who was not affiliated with the study.

    "They definitely made their point that temperatures are elevated. And since we know that elevated temperatures might affect sperm production, this is something we might want to look into," he said. But, "I am reluctantly going ahead with recommendations about laptop use at this point. This is a first-stage study."

    Sheynkin agreed that more research is necessary to prove the link between laptop use and infertility, but he said he felt that the findings so far indicate a need for caution -- especially among laptop users who may be trying to conceive a child.

    "In the questionnaires that I give to my patients before I see them, I ask if they use hot baths or a sauna, and I tell them that they should stop it if they are trying to conceive," he said. "I am now going to start asking if they use laptop computers."

    The results of the study will be published in the February 2005 issue of the journal Human Reproduction.

    What 'normal' guy sits with his thighs together? and if I was in some kind of study and they measured my scrotal temperature they better be paying me something!!! pfff...oh well

    Many guys probably don't sit like that. However, a lot of people sleep like that. (laying on their side)
    What is worse? Sitting with thighs together for a short time? Or sleeping like that for a longer time?

    Wearing breifs will also lower your sperm count. Testicals are closer to the body, therefore they are warmer. The temperature inside boxers shorts is lower and better for the sperm count.
    Quitmzilla is a firefox extension that gives you stats on how long you have quit smoking, how much money you\'ve saved, how much you haven\'t smoked and recent milestones. Very helpful for people who quit smoking and used to smoke at their computers... Helps out with the urges.

    I saw this on NBC news last night and laughed my ass off. The solution is quite simple. Keep your johnson away from your laptop, always put it on a table or desk, and sit like a guy!

    This is just more hype trying to scare folks. The truth is that you waste more sperm on a pron mag or at the desktop doing your pron surfing than you do in an hour of operating a laptop (unless you're doing the pron thing there too, of course). The family jewels are wonderful machines that replenish completely their supply of joy juice every 24 hours. A 'dead load' would only matter if you're either 1. already having problems with dead loads, or 2. use the laptop sitting in chick position all the freaking time.... ok, 2 might be an issue for some of you... refer to my solution at the top of this page.
    Even a broken watch is correct twice a day.

    Which coder said that nobody could outcode Microsoft in their own OS? Write a bit and make a fortune!

    I tried putting my johnson on a table once, and my mother-in-law almost made her daughter divorce me

    You do realize that the next big product on the market will be a thermal-insulator to keep one's johnson at the precise correct temperature all the time. It will be sold mass-market in the Wal Mart and on infomercials, and advertising will be aimed at male laptop users. I so predict. Hide and watch...

    /slightly off topic

    Be careful what sort of table you put your laptop on, or put a mat under it. I have seen a couple of nice tables damaged by the heat. They both cost around $500 to be restored French Polished surfaces and heat don't mix!
