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.

Since then, he’s written and edited 6 books on the subject of natural health, diet and fitness. During this time, he’s constantly been humbled by what experts claim they know and what actually is true. This has led him to experiment with many diets and protocols — including vegan, raw food, fasting, medical treatments and more — to find out what is myth and what really works in the real world.

    Probiotics may be one of those “missing links” in terms of achieving ideal health. As more and more research comes out, it seems there isn’t a single thing in the body that gut bacteria doesn’t have at least an indirect effect on.

    I’m a huge fan of cultured foods. I make my own kefir on occasion, but I particularly love having a large container of homemade cultured vegetables. It’s actually a very easy way for me to eat vegetables (like cabbage) that I normally wouldn’t care for.

    This was a Dr. Mercola article, so not sure what you mean by “Exclusive” Renegade Health article.

    I take probiotics every day. They are good for the immune system.

    Did they say what comprised “standard mouse meals”? I thought they were scavengers.

    Vanilla yogurt usually has added sugar, check the labels in the store. It could have been the sugar, the vanilla, the milk (mice don’t usually milk cows), or just the added protein.

    Sounds like “research” sponsored by the dairy industry. 🙂

    Hi Kevin, you mentioned in one of your article about your digestive problem and use of dairy probiotics that helps you. Can you write something more about that please
    best regards

    Raw kefir employed everyday why stop?

    I am always amazed at what we teach our children. Especially our boys. Will it never end!

    Interesting article, Kevin. As you know, it seems like more and more research keeps pointing to the fact that it is important for health to have cultured foods and/or a probiotic. I have your book “Cultured” and want to start culturing food. I already make kefir, and want to start making yogurt as well. Thank you for the information you bring to your viewers. What you do is so valuable and so worthwhile. I hope the pregnancy is going well (which I’m sure it is)!!

    I wish I was awake enough to remember the details of the NPR interview this morning on allergies and their increase. A lot of info on how ‘clean’ we have become and that kids who are still growing up on farms are significantly more healthy than city kids. Part of the information included noting the drinking of raw milk in these farm families studied. I was getting excited to hear about raw milk getting positive notes when the person then went directly into stating that raw milk has lots of potential bad bugs and people should not make it part of their diet. So if your parents did not get the message about the dangers of raw milk and let you have it, well lucky you. Everyone else, its too late, your immune system can’t handle it. 🙁

    I am on my fourth batch of home made yoghurt. I never noticed before, but in my area, all the ‘Organic’ milk is “Ultra Pasteurized” while the conventional is just pasteurized and homogenized. Hmmmm.
