Medical researchers from the University of Italy, the University of Italy, studied 85 men working at highway toll stations and found that the number of sperm sperm is no different from other young men in the same area, but sperm vitality weakened. Thereforedecline.In this study, the staff of the highway toll stations have undergone a comprehensive physical examination. 83%of men are married, of which 7 of the 71 people have no offspring after marriage.
If men are exposed to the automotive exhaust gas environment for 6 hours a day, the male hormone levels in their bodies will not change, but the ability of sperm activity will decline, which will affect the ability of fertilization.About one -third of women are caused by abnormal number and quality of men.The number of men's sperm, if less than 20 million sperm per milliliter semen, has poor fertility.The weakening of sperm vitality, and abnormal morphology can also affect men's fertility.
Researchers believe that these men have worked in high concentrations of high -concentration nitric oxide, sulfur dioxide, carbon monoxide, and lead and other vehicle exhaust gas environments. Nitrogen dioxide and lead are the most likely to damage sperm quality.Researchers have called for a deeper research on this topic. At the same time, health workers should also pay attention to the negative impact of environmental pollution on human health, pay attention to people's health, and focus on human reproductive capabilities.
