Our happy hour fact to amaze your drinking buddies with.

The sperm count of soda drinkers is lower than those who abstain from carbonated soft drinks.

Responding to an increase in soda consumption among Danish teens, researchers at Copenhagen University tested the sperm quality of 2,500 young men. Those who consumed a liter of cola per day average 35 million sperm per milliliter, whereas those who generally stayed away from the sugary drinks pumped out 50 million sperm per milliliter.

While this suggests caffeine could be the culprit, previous research into coffee and tea consumption hasn't shown that they significantly reduce sperm counts or increase infertility. It is also possible that the sedentary lifestyle associated with the most enthusiastic of soda drinkers is bad for general sperm health.

So yeah, that Mountain Dew high might cost you more than just a day wasted playing "Grand Theft Auto."
