Many men consider yoghurt to be a snack reserved solely for females. A recent study, however, may have even the most rugged heterosexuals strolling the dairy isle for a few cartons of Yoplait.
Scientists examining yoghurt's ability to fight obesity on mice found that not only were the creatures slimmer and fitter, they also had much larger testicles.
The researchers, Eric Alm and Susan Erdman at the Massachusetts Institute of Technology, fed one group of mice a normal mouse diet and another group the same diet with a small serving of vanilla yogurt.
It didn't take them long to notice a few unexpected differences. Alm and Erdman believe the yoghurt-eating mice had a certain "swagger".
"You know when someone's at the top of their game, how they carry themselves differently? Well, imagine that in a mouse," Erdman said, while noticing the animals' "testicles were protruding out really far".
In fact, the mice had testicles five per cent larger than the ones on a yoghurt-free diet and 15 per cent larger than mice on an unhealthy "junk food" diet.
"Almost everything about the fertility of those males is enhanced," Erdman said. "There were legitimate physiological differences in males fed probiotics, not just the extra sexiness."
Whether it's the probiotics in the yoghurt that's causing inflated balls is up for debate, as the study is ongoing. However, if you'd like to snack a little healthier and avoid a ribbing from your mates, just tell them yoghurt helps you ejaculate like a porn star. That'll shut them up.
