Researchers who recently undertook a study with mice in hopes of confirming earlier reports that eating yogurt can help prevent age-related weight gain have discovered a number of unexpected side-effects in their rodent subjects.

First, the Massachusetts Institute of Technology scientists realized that the yogurt-eating mice had shinier, silkier, and thicker coats than the non-yogurt-eating control mice.  Then they noticed that the male mice were walking with a “mouse swagger,” which turned out to be due to testicles that were 5% heavier than those of mice fed a standard mouse diet and a full 15% heavier than those of mice forced to live on high-fat, low-nutrient junk food.

And finally they conducted mating experiments and found that yogurt-eating males “inseminated their partners faster and produced more offspring,” while yogurt-eating females gave birth to larger litters and were more successful in raising them to the age of weaning.
