I have often thought about the heat of laptops being held in laps, especially related to reducing sperm production. I have often noticed DH using his laltop that way for hours right before bed, which would be prime baby-making time in many families, and we know sperm are sensitive to heat. I mean, if briefs can possibly raise sperm temperature enough to reduce fertility, I assume a laptop in the lap could too. Not sure if I've thought about that related to fetal development/pregnancy, but they say you shouldn't take full immersion baths while pregnant, don't they? Wonder how much your body heats up while holding a laptop.
Since my thoughts are all about heat, not radio waves or antyhing else, anything that buffers the heat would suffice for me. I use a lap desk just for my own comfort, unrelated to pregnancy. Bed Bath and Beyond has several, if you google lap desk.
