Sperm Like Alcohol But Not Cell Phones

The Nofer Institute of Occupational Medicine in Lodz, Poland, released a study finding that men who drank wine in moderation regulary had stronger swimming sperm. (There's not mention of beer, but I would expect a similar result.) Other factors that turn your sperm into tiny Micheal Phelpses are increased leisure time, light coffee drinking and wearing boxer shorts.

However, don't use your smart phone to post your drink to Untappd. Regular use of a mobile for more than a decade will decrease the mobility of sperm.
