Though scientists haven't confirmed if a GSM or CDMA signal can inflict more damage, the study did show that men who carry their cell in their front pocket show a lower-sperm concentration. Additionally, test subjects exposed to radio-frequency electromagnetic radiation (emitted from cell phones) showed decreases in sperm concentration and motility — the ability of a sperm to move toward an egg. That's concerning for any couple trying to conceive.
How can you combat the effects of cell phone radiation on your man's sperm count? Try a man bag — they're so in right now.
