Why are vitamin supplements helpful for sperm motility?

Sperm production requires many nutritional elements such as protein, amino acids, minerals and vitamins. Many vitamins are closely related to sperm production and function, such as vitamin C, which reduces sperm agglutination and facilitates the liquefaction of semen.
The genetic DNA in sperm sex cells is protected by the antioxidant function of vitamin C. Vitamin E has a role in regulating the gonads and extending sperm life.
