A recent study has revealed that men who consume Coca Cola and Pepsi may have larger testicles and higher testosterone levels.
While it has long been speculated that fizzy drinks can affect men in various ways, recent research has shown that certain carbonated beverages may boost the size of their testicles.
The study, conducted by Northwest Minzu University in China, examined the impact of carbonated drinks on fertility and sexual organs in men using three groups of mice: one drank only water, the second consumed different levels of Coca Cola, and the third drank the same amount of Pepsi for a period of 15 days.
The study included weighing the rodents’ testicles and drawing blood on day one, five, seven, 10, and 15. Results showed that mice drinking pure Coca-Cola displayed higher levels of the male hormone compared to those drinking water.
The study concluded that “Drinking Coca-Cola and Pepsi-Cola could promote testis development and enhance testosterone secretion […] the findings provide scientific bases for fully understanding the effects of carbonated beverages and their mechanism on development and reproductive functions of humans, and also benefit the prevention of prostate dysfunction and cancer.”
However, these findings contradict previous studies that imply sugary drinks make men less fertile. Before this study, a survey of 2,500 men found that those who drank a liter of cola per day had 30% fewer sperm than those who did not consume fizzy drinks. Additionally, other research suggests that caffeine can boost testosterone levels.
