What Foods Naturally Produce More Testosterone?

Testosterone is a male hormone produced in the testes. In men, testosterone maintains bone density, muscle mass, sex drive, sperm production and fat distribution, according to the Mayo Clinic. Testosterone levels drop about 1 percent each year after age 30 in men, the Mayo Clinic continues. Some men may seek testosterone therapy to increase energy levels and youthfulness. But foods high in zinc may naturally increase testosterone levels in men.

Oysters

A 1996 study published in "Nutrition" investigated zinc status and testosterone levels in healthy men ages 20 to 80. The study showed men with low serum zinc levels also had low testosterone levels. When dietary zinc increased, so did the testosterone levels. Oysters contain more zinc per serving than any other food, according to the Office of Dietary Supplements, with 76.7 milligrams of zinc in six oysters. They are also a good source of protein, carbohydrates and healthy fat. Raw oysters should not be consumed by men with impaired immune systems, liver disorders or cancer, according to the Global Gourmet.

Beef Shanks

Beef shanks also contain high amounts of zinc, although not as much as oysters. A 3-ounce portion of beef shank contains 8.7 mg of zinc, according to the Office of Dietary Supplements. Beef shanks come from the lower portion of the front or rear leg of the cow. The tough meat on the beef shank is best served after simmering slowly in broth or water. Ground shank beef also makes good chili, according to the website Chow.

King Crab Legs

Hypogonadism, a low production of testosterone, can develop in men with inadequate intakes of zinc, according to the Office of Dietary Supplements. Men need 11 mg of zinc a day to prevent deficiencies. A 3/4 to 1 pound Alaskan King crab leg provides about 26 to 34 mg of zinc.

Cashews

Animal products are the best sources of zinc. But for men who do not eat meat, cashews may serve as a source of the mineral. A 1-ounce portion of cashews provides 1.6 mg of zinc, according to the Office of Dietary Supplements.
