The results of a recent Danish study appear to link excessive drinking of soda to infertility in males, but it’s important to realize that this study does raise some serious questions and should only be used as an educational tool at this point.

Key points of the study include:

• The study was conducted on 2,554 Danish men between 2001-2005. 
• Each week, some of the men drank at least 14 liter bottles of soda containing a minimum of 800 mg of caffeine per day.  The control group drank a more moderate amount of soda and caffeine.
• Semen samples were used throughout the study to determine if the soda drinking was having an effect.

The results?  Men who drank soda excessively had a lower sperm count. 

But before you swear off an afternoon Coke or Pepsi pick-me-up, it’s important to remember that the study, while interesting, raised some questions. 

For instance, similar studies done on caffeine alone showed that the ingedient caused little to no change in sperm count or viability.  Plus, the Danish study didn’t consider other nutritional possibilities, such as that excessive soda drinking could contribute to eating unhealthy foods (which could lead to lowered male fertility rates.)

In the end, it’s probably best to simply adopt a healthy diet until more information connecting soda and male infertility can be unearthed.
