““Zinc Zinc has significant effects on male sexuality, including sperm motility and production, erections, and even testosterone levels. Because the transformation of androstenedione to testosterone depends on a zinc-dependant enzyme, zinc intake significantly affects testosterone levels in the body. One study found that sixty milligrams of zinc daily for fifty days increased serum testosterone levels. Because DHT is metabolized from testosterone, a subsequent rise in DHT levels was also seen. Testosterone and DHT levels only increased in those men whose testosterone levels were low. Normal men experienced no increase.””
