According to statistics, about 15 percent of married couples are infertile, with male causes accounting for about 49 percent. Danish reproductive scientists have found that over the past 50 years, male sperm count has decreased by about 50 percent. Sperm count reduction is one of the main culprits leading to male infertility. In the past 10 years, both domestic and foreign reproductive scientists have been devoted to finding the causes of male infertility. There are many causes of male infertility, but research data in recent years show that certain lifestyle fads are to blame. 1, fast food food: with the modern pace of life continues to accelerate, in order to save time and convenience, more and more men to join the ranks of eating fast food. Fast food contains a lot of soy products. But soy contains a hormone similar to estrogen, if the intake of this hormone is larger, it will show some of the effects of human estrogen, thus inducing male reproductive problems. 2, candlelight dinner: eating by candlelight, mood and atmosphere is there, but may bring some harm to the body. Candles, especially scented candles, will release lead, mercury and other harmful particles. Lead can prevent the testes from synthesizing androgens and sperm production. Mercury, on the other hand, makes your libido diminish, or leads to penile erection, which in turn leads to infertility. 3, like to drink coffee: medical research has found that coffee will also damage male sperm, long-term coffee drinking men, not only the number of sperm significantly reduced, sperm activity is also significantly weakened. Due to the caffeine contained in coffee makes the sperm inactive, so British scientists recommend that men drink coffee in moderation. 4, do not like to drink water: do not like to drink water can also lead to male reproductive problems. Although scientists have not yet fully understood how the lack of water specifically affects male reproductive health, but the facts show that men who love to drink water have a stronger reproductive capacity. 5, overeating: American scientists in Atlanta found that when men overeat, the quality of their sperm will be damaged. Because from a large number of food intake of excessive fat and other nutrients to make the sperm temperature rises and damage. 6, like to eat seafood: Hong Kong, China scientists have found that because the ocean is subject to industrial pollution, so the seafood contains too much mercury, a chemical harmful to reproduction. Therefore, excessive consumption of seafood will make the blood of mercury content increases, ultimately leading to male infertility. 7, smoking, drinking: smoking has always been the enemy of health, the impact on semen is equally obvious. Overseas studies have shown that the probability of infertility in men who smoke regularly is three times higher than that of non-smoking men, and that smoking does the most damage to the reproduction of men between the ages of 30 and 40. Compared with non-smokers, smokers have a significant decrease in all major indicators of semen quality, a higher rate of sperm deformities, and an increase in the number of white blood cells in semen. Nicotine and polycyclic aromatic hydrocarbons produced in tobacco cause testicular atrophy and altered sperm morphology. Alcohol has a direct effect on the human liver and male testes. Studies have found that patients with chronic alcoholism experience testicular atrophy, leading to a decrease in semen quality. Therefore, men must avoid regular excessive alcohol consumption. 8, food packaging: German reproductive scientists found that the global decline in male sperm count may be related to a chemical called phthalates. It is a class of chemicals that can play a role in softening, is commonly used in toys, food packaging, vinyl flooring, wallpaper, detergents, lubricants, nail polish, hair sprays, soaps and shampoos and hundreds of other products. Studies have shown that phthalates can be endocrine disruptors, causing male sperm to decrease in number, low motility, abnormal morphology, and in severe cases, can lead to testicular cancer, which is the “main culprit” of male reproductive problems. Phthalates can also enter the body through food and water packaged in plastic containers, such as the inner coating of canned food, recyclable milk and mineral water bottles. Studies have shown that the higher the fat content of canned food, the more likely to be contaminated food, such as pork, anchovies, sardines and so on. 9, bubble oxygen bar: in recent years, oxygen as a new means of health care in some cities in China popularized, many people to bubble oxygen bar for fashion. In this regard, experts warn: healthy people, especially men of childbearing age should not catch this fashion. Inhale more than physiological needs of oxygen, will involve the testicles and the metabolism of sperm cells. 10, sauna: sauna can make people eliminate fatigue, and has the effect of health, many people enjoy this way. However, experts warn: it is the sauna bath into some of the youth infertility culprits. Sperm born in the testicles, the temperature requirements are more stringent, must be in 34 ℃ ~ 35 ℃ under constant temperature conditions in order to develop normally, and the temperature in the sauna room is much higher than this standard. Therefore, has not yet given birth to young men, into the sauna should only occasionally for, often patronized I am afraid that will be a small loss. 11, disposable diapers: Recently, German scientists found that many young parents feel convenient, worry-free diapers will cause male babies grow up sterile. Due to the plastic lining of disposable diapers so that the heat in the testicles around the gathering. When using disposable diapers, the surface temperature of the scrotum rises significantly, in the highest case 1 ℃ higher than the body temperature, in which the younger the infant scrotum temperature is higher. Prolonged high temperature affects the development of testicles, and some children are also left with the sequelae of infertility. 12, often wear tight pants: many young men chasing the fashion of tight pants, perennial jeans do not leave the body. Unbeknownst to them, jeans will scrotum and testicles tightly bound, so that the local heat dissipation is reduced, causing testicular temperature rise, hindering sperm production. At the same time, tight pants limit the blood circulation in the scrotum area, especially the obstacle to the return of venous blood, resulting in testicular stasis, bringing resistance to sperm production. 13, cosmetics: part of the male skin care random use of female cosmetics. These cosmetics developed specifically for women, some contain a certain amount of estrogen, long-term use of male reproductive health will be damaged, resulting in reduced sperm count in the semen. 14, frequent use of cell phones: Hungarian scientists believe that the high-frequency microwaves emitted by cell phones will cause a sharp decline in sperm count, sperm vitality decline. Although this conclusion did not obtain consensus, but an undeniable fact is that long-term use of cell phones in men’s reproductive capacity is indeed lower than the non-use. Therefore, men of childbearing age should pay attention to self-protection when using cell phones, try not to use cell phones when there is an ordinary phone around, and try to talk long and short when using cell phones to make phone calls. Eat more food rich in high-quality protein, phospholipids and B vitamins, in order to enhance the ability to resist radiation and protect the function of reproductive organs. 15, laptop: long-term regular use of laptops will also damage male reproductive health, because the laptop heat emitted when working will inhibit the production of sperm. Therefore, when using a laptop, it is best not to put it on your lap. 16, driving: the development of modern transportation, so that the car has become a reflection of male identity. Italian researchers found that cab drivers, professional drivers, truck drivers have the most obvious decline in fertility. Continuous driving more than 2 hours is enough to damage the quality of male sperm. When driving men should drive 1 hour to leave the car activities for 10 minutes. 17, noise: with the development of modernization, the health impact of urban noise is more prominent. Noise is a kind of environmental pollution. In recent years, some experts put forward the “environmental hormone” theory, pointing out that there are chemicals in the environment that can affect human endocrine function like hormones, noise is one of them. Noise is one of these chemicals. It can cause endocrine disruption in the human body, leading to semen and sperm abnormalities. Prolonged noise pollution can cause male infertility. 18, traffic pollution: car exhaust contains a large number of harmful substances, such as sulfur dioxide, carbon dioxide, lead and other pollutants is another killer of male reproductive problems. The human body is exposed to these substances for a long time, cumulative damage will occur, not only affect reproductive health, but also may increase the incidence of tumors and other diseases. The most serious is that the dioxin contained in automobile exhaust is an extremely strong environmental endocrine disruptor, which can cause changes in the morphology of the male testes, a decrease in the number of spermatozoa, and a reduction in spermatogenesis.
