According to a new study from the Massachusetts Institute of Technology (and Harvard researchers back this up), mice that ate vanilla-flavored yogurt grew bigger testicles, were able to inseminate females faster, and produced more offspring.
Researchers used several yogurt brands but "...active probiotic bacteria is likely the important thing." says MIT's Susan Erdman, who co-conducted the study.
Yogurt anyone?!
