Drinking Coca-Cola and Pepsi could increase testicle size and testosterone production, a new study has suggested. Researchers at the Northwest Minzu University in China carried out a fresh study, after previous investigations suggested soda consumption could reduce sperm count and have a harmful impact on reproduction functions.
Their study, looking into the impact of carbonated drinks on fertility, relied on animal testing - specifically mice. And it found that the male hormone actually increased and testes got bigger.
One group were given only water and the remaining test groups drank varying levels of Coca-Cola and Pepsi over a 15-day period, the Mirror Online reports. The scientists monitored the mice through blood tests, while also measuring weight and diameter of the testis.
