If men are looking for a good excuse to chug the soda, a new study indicates that men who drink Coca-Cola or Pepsi have larger testicles and higher testosterone levels than men who avoid sodas. Scientists draw this conclusion based on a study in rodents.
As per the results published in the journal Acta Endocrinol, soda can do wonders for a men’s fertility. Even though that sounds contradictory to previous claims, researchers from China’s Northwest Minzu University were determined to prove sugary sodas can have a positive impact on men’s reproduction.
Through their study, they discovered that high caffeine intake can boost testosterone production in the body, which results in greater sperm production and larger testes.
In their experiment, there were five study groups: the first group of 30 male mice were trapped in a cage with a water bottle filled with half Pepsi and half tap water. The second group of 30 male mice was provided with just Pepsi with no diluted water. Two more groups of 30 male mice were given the same water bottles except with Coca-Cola. Then, the last fifth control group had only water.
This experiment went on for 15 days. The testicles of all the mice were measured at the start of the study, at the end, and four times during the study.
The results reveal that the mice’s testicles were significantly higher in the groups that drank 100 percent Coca-Cola and Pepsi compared to the watered-down and control groups. “The outcomes demonstrated a high dose of Pepsi-Cola or Coca-Cola could promote testis growth and development,” the study reported.
The control group’s testosterone concentration was 23 nanomoles per liter and the groups that drank pure cola had a concentration of about 30 nanomoles per liter.
There’s no need to cut back on sugary soda to enhance fertility rates for men. A sip could be beneficial according to these researchers.
