How to improve sperm quality before pregnancy? Arginine is the main component that constitutes the head production of sperm and to improve the ability of sperm activity. Foods rich in arginine include sea cucumber, eel, loach, cuttlefish and sesame, yam, ginkgo, tofu skin, frozen tofu, peanut kernel, sunflower seeds, hazelnut, etc. For example, sea cucumber has been regarded as a precious product to nourish the kidneys and benefit the essence, aphrodisiac and cure impotence since ancient times. Consume foods containing magnesium. Magnesium helps regulate human heart activity, lower blood pressure, prevent heart disease, and improve men’s fertility. It is recommended that men should eat 2 bowls of oatmeal with milk and 1 banana for breakfast. Foods containing magnesium are soybeans, potatoes, walnuts, oatmeal, macaroni, leafy vegetables and seafood. Sperm is rich in trace elements of zinc, zinc plays an important role in maintaining the reproductive function of male political parties. Because zinc is essential for sperm metabolism and enhances the vitality of sperm, it is necessary to eat more zinc-rich foods such as oysters, shrimps, clams, shellfish, animal liver, pecan nuts, cow’s milk, beans, bran and lotus seeds. The zinc content of oyster meat is the highest among all things, so focus on intake helps sperm nucleic acid and protein metabolism, and can improve sexual performance. However, the daily amount of zinc should never exceed 15 micrograms, because overdose of zinc can affect the role of other minerals in the body. 120 grams of lean meat contains 7.5 micrograms of zinc. Calcium plays a pivotal role in the movement of sperm, energy acquisition, maintenance of hyaluronidase activity and in the fertilization process. If the body is deficient in calcium, it will slow down the movement of sperm and reduce the activity of sperm acrosome protease. So men should also focus on eating more calcium-rich foods, such as milk, soybean products, Jesus fish, ribs soup, nori, shrimp, kelp, wakame, kimchi, mushrooms, mustard, coriander, sweet almonds, raisins and so on. So, when is the best sperm quality for men? 30 to 35 years old is the best age for men to have children, because this is the age when men are in their prime, in addition to the internal advantage of excellent physical quality, other external advantages, such as economic and career tend to be stable, the material conditions for raising children are superior, and the psychological ability to bear is also mature. Although the man has the ability to be a father throughout his life, but from the perspective of eugenics, it is better not to exceed 35 years old. The sperm quality of men reaches its peak at the age of 30, and then lasts for 5 years until the age of 35, after which the quality declines. American scientists have found that 35 years old is a watershed for male sperm quality. The rate of genetic variation in sperm increases dramatically for men beyond this age, and the finding may be the best explanation for the plummeting fertility rate for men over 35. Previously, the common belief was that professional women who were overly focused on their careers would likely have to sacrifice their ability to become mothers, as the quality of women’s eggs declines with age.
