Cell phones can affect sperm quality.

I'm only reprinting this cuz I like when mainstream media says "gonads." From CNN:

Keeping a cell phone on talk mode in a pocket can decrease sperm quality, according to new research from the Cleveland Clinic.

"We believe that these devices are used because we consider them very safe, but it could cause harmful effects due to the proximity of the phones and the exposure that they are causing to the gonads," says lead researcher Ashok Agarwal, the Director of the Center for Reproductive Medicine.
