A new study finds that drinking soft drinks can increase testosterone levels and testicle size in men.
The study aims to determine the effect of soft drinks on fertility.
Previous studies have linked soft drink consumption to reproductive function with lower sperm counts and reduced sperm motility.
“The results show that a high dose of Pepsi or Coca-Cola can promote testicular growth and development,” the study authors said.
In addition to testicular size, the researchers found that “blood testosterone concentrations in all rats were enhanced after drinking Pepsi and Coca-Cola, suggesting that high doses of Pepsi and Coca-Cola could improve testosterone secretion in male rats.”
They concluded the study by saying: “In conclusion, drinking Coca-Cola and Pepsi can promote testicular growth, enhance testosterone secretion, and increase serum epidermal growth factor (EGF) concentrations. Our findings provided the scientific basis for understanding the effects and mechanism of soft drinks on developmental and reproductive functions in humans, but are also useful in preventing prostate dysfunction and cancer.”
Although the study indicated that men may suffer from an increase in testicular size and testosterone production due to drinking soft drinks, the researchers indicated that the results contradict previous studies.
