In recent years, the number of urban cars has grown sharply at about 13%per year. The tail gas pollution of urban automobiles has become increasingly worse. Long -term inhalation of automobile tail gas can reduce the vitality of men's sperm.
Nowadays, with the continuous increase in social pressure, male infertility has also become an upward trend.Sperm is the key to male gestation. The quality of sperm is not good. Of course, it has become one of the causes of male infertility, but this is only a part of the reason. Male infertility may have other reasons.
Men's infertility is an important hidden danger that affects men's health. Air pollution is a major environmental risk that affects health. Italian studies have shown that long -term exposure to traffic pollution will reduce male sperm vitality and affect their fertility.Exhaust gas can also affect men's fertility.
If men are exposed to traffic pollution for at least 6 hours a day, the level of testosterone and other hormone secretion in his body is not low, but the sperm swimming ability will be low, which will affect the ability of sperm and eggs.In addition, nitric oxide and lead in automotive exhaust gas are the most likely to destroy sperm quality. Heavy metals in the tail gas such as lead, mercury, cadmium, etc. are also the enemy.
When traffic jams, many people habitually open the window to breathe.However, the tail gas pollutants discharged by cars are generally gathered in areas 40-50 cm high from the ground.This highly means that if people in the car open the window, inhale the high concentration of exhaust exhaust emission of the vehicle, and open a window casually, even if it is a sunroof, the impact on the people in the car is the same.
Although the air pollution of the car is severe, when the air is moist, such as rain and snow weather, it is also possible to turn on the window and air.However, during the commute period, traffic jams are the most serious, and any window should be avoided at this time.In the case of unsatisfactory air circulation, such as haze and foggy weather, after opening the window, it is also seriously affected by air pollution.
