According to the new 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 scientific evidence proves that drinking cola-based drinks in excess 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 will also lead to “sperm”, fertile men should be alert.
A. Diet
Killer 1: Caffeine in cola
The consumption of cola-type drinks will reduce the number of sperm, the earliest from the experimental results of several doctors at Harvard Medical School. It is understood that their experiment was to put cola-type drinks in direct contact with sperm, thus concluding in the observation that it may 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 volume.
Killer 2: Ethanol in alcohol
The ethanol contained in alcohol can cause an increase in catecholamines. High catecholamines can affect the blood flow to 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 well as the accumulation in the body to become a hidden problem.
Killer 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 spermatogenic epithelial damage. When the environment for sperm growth becomes poor, sperm quantity and quality will also decline. Experts suggest that smoking should not exceed 10 cigarettes a day, otherwise it may be difficult to have children.
Killer 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 we 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 production function.
Killer 5: creamy pastries, French fries trans fatty acids
Cream pastries, French fries and potato chips are very popular foods in urban areas. 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 less consumption of such foods is appropriate, so as not to inadvertently affect reproductive function.
Killer 6: Carcinogens in grilled foods
Grilled and over-fried food can produce a carcinogenic substance called acrylamide, which is toxic to sperm cells. If the single consumption exceeds 1 pound, or 3-5 taels at a time, for several days, it will directly affect the growth and development of sperm.
Killer 7: Celery in the celery apigenin and volatile oil
Celery is coarse fiber food, many constipated people like to eat. Only, the 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.
Second, the environment
Living environment pollution is the biggest killer of sperm. Pollution mainly from.
1, the application of pesticides and insecticides.
The pesticides and insecticides sprinkled into the land will break down the ingredients similar to estrogen, thus producing plants that are both food for people to eat 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 additional substances added contain estrogen analogues, people consuming these foods for a long time may promote premature maturity and lead to reduced masculinity and reduced fertility.
3, hot water baths.
Many studies have suggested that exposure of the testicles to high temperatures can reduce sperm production and cause infertility.
People are placed in nature and industrial environment, fertility is the most sensitive a test of life, if not suitable for survival, reproductive cells are the first to be affected. The normal functions given to us by nature are generally within safe limits and must never exceed the limits of time and dose.
