New study reveals that drinking Coke and Pepsi leads to larger testicles and more testosterone

New study reveals that drinking Coke and Pepsi leads to larger testicles and more testosterone.

A study has revealed how drinking Coca-Cola and Pepsi can lead to larger testicles and higher testosterone levels.

The Northwest Minzu University in China was attempting to determine the impact of carbonated beverages on fertility and sex organs in men.

The study looked at three groups of mice – one that only drank water, another that drank different levels of Coca Cola with another doing the same with Pepsi – over 15 days.

Experts are not suggesting that men should rush out and drink lots of Coca-Cola or Pepsi. Previous studies have linked sugary sodas to a host of health problems including obesity, diabetes, heart disease, high blood pressure and tooth decay.  

Experts from the Northwest Minzu University in China set out to show that sugary sodas were bad for male fertility.

They cited previous research which showed that carbonated drinks had negative effects on female ovaries.

One group of 30 male mice was kept in a cage, and their water bottle was filled with 50 percent Pepsi mixed with tap water.

Another 30 mice were kept in a different cage and given pure Pepsi.

The same was done for two groups of mice but with Coca-Cola. A fifth group was used as a control and given pure water.

All mice could drink as much as they pleased for 15 days. ‘The outcomes demonstrated a high dose of Pepsi-Cola or Coca-Cola could promote testis growth and development,’ the study said.

Testosterone levels were also recorded, and concentrations were found to be enhanced at the end of the study.

On days 10 and 15, the group which drank pure Pepsi had significantly higher concentrations of testosterone than the control group.

After 15 days, the control group’s testosterone concentration was around 23 nanomoles (nmol) per liter, whereas the groups which drank pure Coca-Cola and Pepsi had a concentration that was roughly 30 nmol/L.

The mice who were allocated the pure Coca-Cola also had higher levels of the male hormone than the control group. 

The results suggest that large doses of Pepsi and Coca-Cola could improve testosterone production in male mice.

However, the mice used in the study are non-copulating, meaning they do not mate.

The long-term effects of carbonated drinks on testicle mass and testosterone production are also unclear.

The findings were published in the journal Acta Endocrinol. It was quickly discovered that the mice drinking Coke and 100 percent Pepsi, compared to a mixture of Pepsi and water, had a significant change.

For instance, the mice that were given pure Coca-Cola had higher levels of the male hormone compared to the group that drank water. However, this contradicts previous studies that indicated sugary drinks made men less fertile, instead of more, as the new study suggested.

A previous survey of 2500 men showed those who drank a liter of cola a day had 30 percent fewer sperm than those that drank none. The study aimed to understand the influences of carbonated beverages on testis growth and came to the conclusion that a higher concentration of Coca-Cola or Pepsi could raise testosterone secretion and increase testis longitudinal diameter (TLD), testes transverse diameters (TDD) and serum concentrations.

Interestingly, the study sharply contrasts previous findings which suggested that sugary drinks and processed edibles make men less fertile. The new research, on the contrary, provides some evidences that high caffeine intake can actually increase production of testosterone inside the body, which leads to higher sperm production and subsequently larger testicles. China’s Northwest Minzu University had initially set out to show that sugary sodas were bad for male fertility. However, after mere 15 days, where the mice were divided into five groups, the researchers revealed their shocking results. Incidentally, one group got 50 per cent Pepsi mixed with tap water, the second pure Pepsi, the third and fourth had the same thing but with Coca-Cola and the fifth pure water.

Researchers found that majority of the mice’s testicles were significantly higher in the groups that drank Coca-Cola and 100 per cent Pepsi.
