Men can take folic acid tablets. Folic acid plays an important role in maintaining the proliferation and division of male germ cells. Folic acid is involved in purine and pyrimidine synthesis and plays an important role in protein synthesis and DNA division. In men, primary spermatocytes are formed after spermatogenesis, and primary spermatocytes also need to undergo mitosis to produce secondary spermatocytes, which require folic acid during mitosis. Folic acid plays an important role in animal reproduction, participating in animal reproduction and metabolism and keeping animal DNA from degenerating. Folic acid is a good promoter of reproductive function in both men and women. Men who take more folic acid can also protect the Y chromosome from mutation. Taking more folic acid has a significant promotion effect on maintaining sperm function, increasing sperm vitality and improving sperm malformation rate. Folic acid is widely found in vegetables and fruits, and is contained in a wide variety of foods and vegetables. Most men will not be deficient in folic acid after taking folic acid supplements through food.
