A recent research which 2,554 men, found that cola addicts had an average sperm count of 35million per Millilitre, compared to 56million per millilitre in those who consumed less coke.
While a sperm count of 35million still fall within the normal range it puts men more at risk of eventually becoming infertile.
And scientist noted that while getting an erection relied on a number of factors both physical and psychological- certain ingredients in this fizzy drink appeared to contribute to the problem.
They are claiming that a sweetener in the drink could damage arteries in the pennis, which could prevent blood from flowing freely through it.
It would be assume that maybe caffeine was behind these worrying statistics, but apparently there was no link between caffeine levels in cola and other drinks. So it's likely due to another ingredient.
In conclusion, the scientist who carried out this research has said that the odd can of coke is fine, but it might be worth cutting back if you are on a litre or more per day.
