With the aggravation of environmental pollution, the fertility of human beings is declining, and the emission of automobile exhaust can reduce the fertility of men. A new study believes that long-term exposure to car exhaust will lead to low sperm quality, thus affecting male fertility. This is an issue that people pay special attention to, because it is a major issue involving human survival environment, human reproduction and social development.
Medical researchers from the University of Naples in Italy conducted a study on 585 men working at highway toll stations and found that their sperm number was no different from that of other young and middle-aged men in the same region, but their sperm vitality decreased, so their fertility also decreased accordingly. In this study, the staff of the highway toll station have all received a comprehensive physical examination. 83% of the men are married, and 19 of the 171 married have no children after marriage.
If men are exposed to car exhaust for 6 hours every day, their male hormone level will not change, but their sperm activity will decline, thus affecting the fertilization ability. About one third of female infertility is caused by the abnormal quantity and quality of male sperm. The number of male sperm is very poor if there are less than 20 million sperm per milliliter of semen. Decreased sperm vitality and abnormal morphology will also affect male fertility.
Researchers believe that these men have been working in high concentrations of nitric oxide, sulfur monoxide, carbon monoxide and lead and other automobile exhaust gases for a long time, while nitric oxide and lead are the most likely to damage sperm quality. Researchers call for more in-depth 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 pay attention to human reproductive capacity.
