Calcium plays an important role in sperm motility, capacitation, maintaining hyaluronidase activity and fertilization. If the body lacks calcium, it can slow down sperm movement and reduce the activity of sperm acrosin. So pay attention to eat more calcium-rich foods, such as milk and sweet almonds. Arginine is the main component produced by sperm head, which should improve the ability of sperm activity. Arginine-containing foods include sea cucumber, sunflower seeds, tofu skin, frozen tofu, eel, yam, cuttlefish, sesame and peanuts, and loach and ginkgo are also rich in vitamins.
