Pumpkin seeds are an easily accessible, inexpensive way to load up on a wide variety of nutrients, zinc in particular. Zinc helps improve sex drive in general and is also necessary for the production of healthy, abundant, and potent sperm. Zinc-rich foods help the body produce testosterone, the chief male sex hormone. And with greater levels of testosterone comes increased sperm production. Take it regularly, though: The body has no storage mechanism for zinc, so foods containing the nutrient must be eaten daily for an ongoing healthy sperm count.
