一项研究认为,长时间接触汽车废气会使男性精子质量下降,从而影响男性的生育能力。意大利那不勒斯大学的研究人员对85名在高速公路收费站工作的男性进行了研究,他们中有71人已婚,但其中有7人婚后没有生育后代。研究人员表示,按受调查者的精子数量与同一地区其他中青年男性没有差别,但精子活力减弱。
One study found that long-term exposure to car exhaust will reduce the quality of male sperm, thus affecting the fertility of men. Researchers at the University of Naples in Italy conducted a study of 85 men working at toll booths, 71 of whom were married, but seven of them did not have children after marriage. The researchers said there was no difference in sperm count among respondents from other young men in the same area, but sperm motility was weakened.
