I'm a research scientist in microbiology, so I'm going to read the actual published study and critique it. However my first impression is that the
study is very poorly designed.
Think about it. Even if you sit your lap-top on your lap while using it, there will be clothes, hair (well, maybe not for some
), skin, and other
flesh in between the radiation source and your little soldiers. All of these factors would soak up radiation and potentially significantly decrease
the amount of radiation that actually reaches the sperm. Compare this to the study where the sperm are left "naked" with no barriers between them
and the radiation source.
Also, as the distance between the radiation source and the sperm increases the radiation levels will decrease. I don't know the equation, but it is
probably true that even small increases in the distance between the radiation source and the sperm will significantly lower the quantity of radiation
reaching the nethers.
They mentioned a decrease in motility and an increase in DNA damage, but they didn't mention if they are both present in the same sperm (not in the
news article anyway). Non motile sperm will result in decreased fertility, but the DNA damage is only a concern if it is present in motile sperm
that could potentially fertilize an egg.
Finally, I would like to know what model of lap-top was tested and if multiple models were tested.
Overall this looks like a poorly designed study aimed at creating sensational headlines. Mission accomplished.
Take the advice at the end of the article. If you're spending too much time on your lap top, chances are that lack of exercise and/or poor diet (ie
lifestyle) will have a much more profound effect on your fertility than the radiation coming from the interwebz conection.
