According to the latest issue of the American Journal of Epidemiology, Danish researchers have shown that men who drink 1,000ml of cola a day may kill a significant number of sperm in their bodies. Compared with those men who do not drink cola, their sperm count can be reduced by nearly 30%.
In response to this news, many men questioned whether there were exaggerated ingredients, but drinking cola-based drinks over a certain amount can 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.
Hidden danger 1: Caffeine in cola
The drinking of cola-based beverages will reduce the number of sperm, the earliest from the experimental results of several doctors at Harvard Medical School. It is understood that their experiments involved bringing cola-based beverages into direct contact with sperm, thus concluding in their observations that it could lead to reduced fertility. However, in everyday life, the cola consumed must be absorbed through a series of digestion in the body, rather than coming into direct contact with the sperm vesicles. Therefore, it is not impossible to consume small amounts of cola-based beverages.
However, there is scientific evidence that the caffeine and nitrites contained in colas may affect sperm production and development. Drinking more than 14 bottles of cola-type drinks per week (500ml per bottle, containing 70mg of caffeine) can cause a decrease in sperm production.
Hidden danger 2: ethanol in 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 will accumulate in the body as a hidden problem.
Hidden danger 3: Cigarettes in the nicotine
When it comes to the harmful substances in cigarettes, the first thing that comes to mind is nicotine. In fact, the impact on sperm is not nicotine, but nicotine. It will lead to small blood vessel spasm, affecting the testicles blood function decline, thus occurring nutritional disorders and hypoxia, so that the spermatogenic epithelium is damaged. When the environment for sperm growth becomes poor, sperm quantity and quality will also decline. Zhou Shaohu said that smoking should not exceed 10 cigarettes a day, otherwise it may be difficult to have children.
Hidden danger 4: Isoflavones in soy products
Soy products are rich in vegetable protein and calcium, so it is only natural that they become a common vegetarian food on the table. But you may not know that the isoflavones in soy products have the effect of presenting phytoestrogens, if men consume more than 200g per day, too much estrogen, will inhibit the normal sperm function.
Hidden danger 5: creamy pastries, French fries trans fatty acids
Creamy pastries, French fries and potato chips are very popular foods for urban people. However, the trans fatty acids contained in these foods are hydrogenated vegetable oils, which can damage cardiovascular and have an effect on hormone synthesis. Therefore, doctors recommend that it is appropriate to consume less of these foods, so as not to invariably affect reproductive function.
Hidden danger 6: carcinogens in grilled food
Grilled and over-fried food can produce a carcinogenic substance called acrylamide, which is toxic to spermatogenic cells. If a single consumption of more than 1 pound, or a single consumption of 3-5 taels, eaten for several days, will directly affect the growth and development of sperm.
Hidden danger 7: apigenin and volatile oil in celery
Celery is coarse fiber food, many constipated people like to eat. Only, celery in the celery glycosides and volatile oils have the effect of inhibiting testosterone production, if eaten too much, will also cause sperm damage, or to pay more attention.
Living environment pollution: the biggest killer of sperm
In recent years there have been more and more infertile men. As soon as many patients do hormone tests, they are often found to have abnormally high levels of estrogen. It is reasonable to say that androgens should dominate in a man’s body, and estrogen is only a small percentage. However, if estrogen keeps increasing and androgens are suppressed, the possibility of infertility will become higher and higher.
Pollution in the living environment is the biggest killer of sperm. Pollution mainly comes from.
1, the application of pesticides and insecticides. Pesticides and insecticides sprinkled into the land will break down ingredients similar to estrogen, and the resulting plants produced are both food for humans and feed for animals. People are at the top of the biological chain, eating both plants and animals, and the body accumulates more and more estrogen.
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, cows, 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.
