With the full liberalization of the two-child policy, you need not only money and time, but also a tadpole of good enough quality. However, research shows that the quality of male sperm has been declining year by year in recent years, and it is urgent to fight the battle for the defense of the male “special zone”. In recent years, the quality of male sperm has been declining year by year, which is worrying. From the World Health Organization’s semen density: from the initial 60 million / ml, to 2011, the sperm concentration of the reference value fell to 15 million / ml, foreign scholars have found that: the average number of healthy men’s sperm decreased by 1% per year, suggesting that male fertility is declining. What causes the decline of “tadpole” quality? 1.Smoking: Tobacco smoke contains substances that have been shown to have a huge impact on male infertility all over the world, and the burning of a cigarette releases about 4,000 chemicals. Tobacco through various ways to damage the sperm baby’s three deadly sins: make sperm less, make sperm ugly (deformed sperm increase), make sperm become dull (decreased vitality). 2, drinking alcohol: ethanol may cause an increase in lipid peroxidation and a decrease in glutathione in the mitochondria in the testes, which may cause testicular atrophy. Some investigations have shown that: men who have been exposed to alcohol before birth can cause a decrease in sperm concentration. 3, high temperature: the physiological temperature of human testicles 32 ~ 35 ℃, testicles mainly through the physiological characteristics of the scrotum and countercurrent heat exchange effect cooling. Testicular heat will lead to a decline in germ cell division activity, sperm cell apoptosis accelerated, sperm DNA repair capacity decreased, sperm cell antioxidant inhibition. 4, obesity: obesity will affect the sperm vitality and fast movement ability, increase sperm DNA fragmentation. 5, drugs: drugs (marijuana, ecstasy, psychedelics) and athletic drugs (athletes take: creatine, steroids) on the male reproductive endocrine and male fertility have adverse effects. 6, sexually transmitted diseases: reproductive tract infections caused by inflammation of the accessory sex glands (testicles, epididymis, prostate, seminal vesicle glands, etc. inflammation), affecting sperm production, maturation, and ultimately affect fertility. The man’s stall, known as the man’s “special zone”, in addition to “ding ding”, there are “eggs”, how to protect “ding ding”? “The following are some of the most important things that you can do to protect yourself from the worst of the worst 1, quit smoking and drinking: “Special Zone” good environment is the favorite sperm baby. 2, avoid sedentary, tight pants, sauna, hot water bath: also “SAR” a cool. 3, adequate sleep, appropriate exercise: the essence can be stored. 4, balanced nutrition: (1) more zinc-rich foods: such as beans, peanuts, millet, walnuts, sesame seeds, oysters, beef, chicken liver, eggs, pig liver, etc.; (2) more viscous slippery food: arginine is an essential ingredient in the formation of spermatozoa, and can enhance spermatozoa’s ability to move; (3) arginine-rich foods such as swim bladders, clam paste, eel, sea cucumbers, cuttlefish, loach, yam, walnuts, etc.; (4) eat more Nut food: rich in various nutrients, such as walnuts, pistachios, ginkgo nuts, pumpkin seeds and so on. (5) Avoid taking stimulants and drugs. 6, avoid unclean sex: pay attention to the “special zone” health.
