Massachusetts Institute of Technology (MIT) researchers Eric Alm and Susan Erdman fed 40 male mice and 40 female mice either a standard mouse diet or a diet high in fat and low in fiber (used to simulate a junk-food diet of humans).

Then, Dr. Alm, an evolutionary geneticist, and Dr. Erdman, a cancer biologist, supplemented the diets of half the mice from each group with yogurt.

They found that the yogurt-eating mice had ten (10) times the active follicle density of other mice, which caused them to have a much silkier looking and thicker fur coat than the other mice.

The two MIT researchers also found that the testicles in the male yogurt-eating mice were 5% larger when compared to the non-yogurt eating mice.

And, the yogurt-eating mice had testicles that were 15% larger than those of mice that ate a diet that was similar to junk foods that humans eat.

The 5/7/2012 ABC News article Yogurt Makes Mice Slimmer, Sexier quotes Dr. Alm: “We think it’s the probiotics in the yogurt. We think those organisms are somehow directly interacting with the mice to produce these effects.”
