Using wi-fi on a laptop 'damages sperm', study suggests
 

Surfing the internet on a laptop that is connected with wireless technology can damage sperm counts, a study suggests.

I think the studies which show that the increased temperature from having the laptop on your lap is causing reduced sperm counts are more plausible. The heat generated from the RF signals is neglible.

I just generally don't see that many people actually using laptops in their laps.

(Well, sometimes on the bus.)

Hubby's comment: "Wow, I could have saved myself a lot of pain and stuff had I known this." (He took one for the team two years ago.)

My laptop is usually on my lap unless I am at my MIL's and I use a TV tray.
