Sperm is very important for men and is related to their “sexual” well-being and fertility. Sperm chromosomal aberrations or immature sperm nuclei can lead to abnormal embryo development or termination, and are the most common male factor causing miscarriage in women. Sperm chromatin DNA integrity testing is one of the latest methods to evaluate the functional status of sperm nuclei. Men who live and work in an environment with high temperature, volatile chemical gases, noise, and radiation for a long time will have poorer organism function and mental stress, which affects the function of sperm. In case of nodules with the egg, it may lead to miscarriage. We know that harmful chemicals can seriously harm human health, such as benzene, mercury, cadmium, pesticides, etc. The harmful substances can be inhaled into the human blood through the lungs and can reach all parts of the body with the blood flow, which can affect sperm production and sperm quality, which in turn affects the growth and development of the embryo. The actual fact is that there are a lot of sperm-killing foods that men don’t know are eroding the sperm, and male experts have inventoried the following, take a look at them. Alcohol: The ethanol contained in alcohol can cause an increase in catecholamines. High catecholamines can affect the blood flow in the testicles, causing premature shedding of immature sperm or unfavorable maturation of sperm in the epididymis, and can lead to atrophy of the spermatogenic epithelium. Therefore, the amount of alcohol consumed must be limited. If the alcohol concentration in the body is greater than 80mg/liter, the damage to sperm will be obvious. Even if you just drink low alcohol, the total amount of drinking too much, as will accumulate in the body to become a hidden problem. Milk tea: The pearl milk tea currently on the market is mostly made with cream, color, flavor and tap water (referring to the pearls in milk tea). The main component of the creamer is hydrogenated vegetable oil, which is a trans fatty acid. Trans fatty acids reduce the secretion of testosterone, which negatively affects the activity of sperm and interrupts the reaction process of sperm in the body. Fried chicken: summer love to eat barbecue men pay attention to, barbecue and fried starchy food contains carcinogenic toxic acrylamide, can lead to male less, weak sperm. In addition, heavy metal cadmium, pesticide residues are toxic to sperm. Coke: Coke contains caffeine and nitrite may affect the production and development of sperm, drinking more than 14 bottles of cola-type drinks (500ml per bottle, containing 70mg of caffeine) per week will cause a reduction in the amount of sperm. Cigarettes: When it comes to the harmful substances in cigarettes, the first thing that comes to mind is nicotine. In fact, it is not nicotine that affects sperm, but nicotine. It causes small blood vessels to spasm, affecting the testicles blood function decline, thus occurring nutritional disorders and oxygen deprivation, so that the spermatogenic epithelium is damaged. When the environment for sperm growth has deteriorated, sperm quantity and quality will also decline. Many men question whether there are exaggerated ingredients, but drinking cola-type drinks above a certain amount will indeed affect sperm production and development. In addition, cigarettes, alcohol and soy products, cream products, potato chips, barbecue food and celery and other foods, in the case of excessive consumption can also lead to “kill sperm”, fertile men should be alert. The pollution of the living environment is the biggest killer of sperm. The main sources of pollution are: 1. The application of pesticides and insecticides The pesticides and insecticides sprinkled into the land will decompose components similar to estrogen, thus producing plants that are both food for humans and feed for animals. As people are at the top of the biological chain, plants and animals eat both, and more and more estrogen is accumulated in the body. 2, artificially add additives to the diet In order to improve production, unscrupulous farmers raise fish to inject growth factors, feed contraceptives to snappers, and raise pigs, cattle, chickens, ducks and geese with feed additives. These extra added substances contain estrogen, long-term consumption of these foods can promote premature maturity, and lead to reduced masculinity and fertility.
