The Secret Ingredient for Boosting Male Sexual Prowess… You May be Surprised : Exclusive Renegade Health Article

New research shows that male mice fed yogurt had larger testicles, increased male “swagger,” and more offspring.

Ever see a man in a yogurt commercial? Ever see your husbands, sons, or dads eating yogurt? It’s not a common occurrence in most households, which, as it turns out, may be too bad.

Yogurt may be seen as a “girlie” food by many boys and men, but according to a new study, it’s actually quite the opposite.

Yogurt Study Finds Surprising Results
Researchers from the University of Massachusetts Institute of Technology wanted to better understand the effects of yogurt on obesity, so they took a group of 40 male and 40 female mice and fed them either a high-fat, low-fiber, low-nutrient diet meant to mimic junk food, or standard mouse meals. They then supplemented half of each group with vanilla-flavored yogurt.

They wanted to see how a probiotic diet might affect rates of obesity, but they got more than they expected. First, the yogurt-eating mice were incredibly shiny. The researchers noted they had 10 times the active follicle density of other mice, resulting in luxuriantly silky fur. Second, the yogurt-eating mice projected their testes outward, showing “mouse swagger.” Their testicles were also about 5 percent heavier than those mice fed typical diets alone, and around 15 percent heavier than the junk-eating mice.

It wasn’t all aesthetics. The yogurt-eating males inseminated their partners faster and produced more offspring than control mice.

Of Mice and Men and…Yogurt?
Researchers theorized that the probiotic microbes in yogurt might have helped to make the animals leaner and healthier, which indirectly improved sexual machismo. They went on to look at the association between yogurt intake and semen quality in men, and so far, have found similar results.

If that’s the case, maybe yogurt should become a new addition in many men’s diets? Whether or not that will happen remains to be seen, however. According to a study by Northwestern University, boys are taught that such foods as red meat and beer are masculine, while vegetables and yogurt are feminine. As a result, according to researchers, men “tend to forgo their intrinsic preferences to conform to a masculine gender identity.”

How About Women?
So far there don’t seem to be any similar studies showing sexual benefits of yogurt or probiotics for women. Research has shown, however, that the active cultures may discourage vaginal “yeast” infections, may reduce a pregnant woman’s risk of preeclampsia (increase in blood pressure after 20 weeks), and may even help boost levels of HDL “good” cholesterol.

Options for You
Whatever you may decide, realize you have options. If, as the researchers believe, it’s the probiotics in yogurt that caused the sexual benefits, you don’t necessarily have to eat more yogurt. Some other sources of probiotics include:

  • Cottage cheese
  • Kefir
  • Buttermilk
  • Sour cream
  • Cream cheese

Vegan sources of probiotics include:

  • Miso, tempeh
  • Soy yogurt
  • Non-dairy yogurt, made with legumes and nuts
  • Fermented vegetables, such as pickled relish, horseradish and tomato salsas, or kimchi (made from fermented cabbage) and sauerkraut
  • Kombucha (fermented tea) or water kefir (similar to Kombucha and ginger beer)
  • Ginger beer
  • Raw coconut yogurt
  • Coconut kefir (probiotic beverage prepared from young coconut water and a starter culture)

Of course, there’s no guarantee it was the probiotics that created the effects in the aforementioned study—that’s still a theory at this point. For other natural ways to boost testosterone levels, check out our article on the subject.
