Yeah, I'm not really following this: Guys who are on their cell phones for four hours a day or more have dramatically reduced sperm counts. Which head are they holding that thing against?
The findings are preliminary and unclear [duh], and scientists are calling for more research. I'd suggest looking into the connection between testicle size and non-stop use of a Bluetooth headset, but I think we all know the answer to that one already.

Hmm.. maybe I ought to stop carrying my phone in my pocket.
