We all crave a healthy sex life, am I right? Whether you’re with the love of your life and want to keep it hot and spicy or you’re single and want to keep it regular, we all want to find that little something extra to keep that sex drive going strong. But what is that secret ingredient? Scientists may have found out what it is.

In a recent study, a group of mice were split in two. One set was fed a diet which included probiotic yogurt and the other half was fed a more junk food diet. The mice fed with yogurt had testicles 5x larger than the other mice eating junk food. What caused the mice’s sexy swagger? Scientists think it was the probiotics in the yogurt. Is yogurt the key to keeping ourselves sexual satisfied?

In the human world, yogurt can be associated with weight loss but not so much with sexiness. However, there is a stack of foods that you can add to your diet to keep that libido nice and strong. It’s The Testosterone Diet. Add these foods and you may just get a little boost down there… and in the bedroom.

Nuts

Snack on two handfuls of almonds or walnuts a day. They’re packed with amino acids like arginine, which improves blood flow throughout your body—including down there, where better bloodflow means a stronger erection. Plus, studies have found that guys with diets high in monounsaturated fats—the kind in avocados, olive oils, and nuts—have higher testosterone levels than those who skimp on the healthy fats.

Oysters

Casanova supposedly ate 50 every morning for breakfast. He was onto something. The shellfish are ultra high in zinc—key in sperm production and blood circulation. But you don’t need to chow down 50 to get your fill of the mineral—six will provide double the recommended daily amount, 15 mg. Some other good sources of zinc are eggs, crab, fish, and dark chocolate.

Oatmeal

Why it works: Oats are packed with L-arginine, an amino acid that works with nitric oxide to reduce the stiffness of blood vessels. L-arginine has been used to treat erectile dysfunction because it helps relax muscles around the penis’ blood vessels. When they expand, bloodflow increases so you can keep an erection.

Balance Your Booze

That third or fourth beer isn’t doing anything for your gut or your T levels. Men who boozed even moderately every day for three weeks saw a 7 percent decrease in testosterone levels, according to a recent Dutch study. Your move: Stick to a glass or two max a night to avoid a drop.

Choose Organic

That apple might not look dangerous, but after reading this you may want to reconsider any previous organic scoffs: A 2011 study published in Environmental Health Persepctives found that of 37 pesticides used on foods, 30 have negative effects on your reproductive system. The chemicals can block testosterone and could be to blame for low sperm count.
