So instead of spending a fortune on birth control..

I could just sleep with a laptop on my crotch? o_O?

The infertility is caused by the ambient heat generated by the laptop. The function of the scrotum is to keep the testicles at a slightly lower temperature than the rest of the body. This lower temperature is more ideal for spermatogenesis, and anything that alters that temperature homeostasis is bound to have negative effects on sperm production.

The cancer risk? I'd like to see the medical journal that proved this and look at their numbers to see what kind of confidence interval and power they're working with to try and prove this. Honestly almost everything can be linked to causing cancer, and from my understanding of this they probably are linking long-term physical damage (ie. Toasted Skin Syndrome) and how that can lead to faster cell turnover which can increase cancer risk.

What a ridiculously over-complicated way to put things! "Toasted leg syndrome"

I guess we better also watch out for burnt tongue syndrome from hot cups of coffee.

wait a minute... what's that smell of burning hair and flesh?
Nevermind.. I've got several hours of videogames to play.

Ow, my balls.

Two things to say:

1 - Putting a pillow underneath your computer reduces airflow to the computer and raises heat levels inside the machine. Increased heat in the computer leads to shorter life (heat damages parts) and/or lower processing speed (most computers now will trade off processing power for heat reduction).

2 - They refer to "laptops", and show mostly Macs. Apple actually stopped calling them "laptops" many years ago for just this reason. If you Google search "apple laptop", you'll find links to pages on Apple's site, including their store. But once you get to their actual site, you won't find the term "laptop" anywhere.

and apple knows why because their lap..tops get extremly hot..

writing this on a macbook pro on my lap.
