Update : 28 Feb 2014, 11:03 PM

If you’re trying to have a baby, it might be a good idea to keep an eye on your partner’s cola intake, as a Danish researchers have found that big cola drinkers can have sperm counts up to 30% lower than normal. While most of the sperm counts would still be considered normal by the World Health Organization, men with fewer sperm generally have a higher risk of being infertile.

Researchers were looking for a link between caffeine and male fertility but found lower sperm counts were not the result of the caffeine in cola, as was previously thought, reported in

The researchers studied sperm samples taken from 2554 young men during their physical examinations for Danish military service between 2001 and 2005. The men were also surveyed regarding their intake of caffeine from various sources, including cola, and asked questions about their lifestyle and diet.

Results showed those with a high intake of caffeine and cola (more than 800mg per day and more than 14 500ml bottles a week) did show a lower sperm count, although the figure was only significant for those who drank a lot of cola. The 93 men who drank a litre or more of cola a day displayed a much lower count. The study was published in the American Journal of Epidemiology.
