杀手一:污染空气中的氧化氮和铅一类的污染物质,是男性生殖问题的杀手。科学家发现,每天在高速公路附近工作或生活6个小时以上的男性精子质量,明显比同样年龄的其他男性差。中国香港的科学家发现,因为海洋受到工业污染,所以海鲜中含有较多的对生殖有害的化学物质汞。因此,过多食用海鲜会令血液中的汞含量增高,最后导致男性不育。杀手二:抽烟经常抽烟的男性不育率是从不吸烟男性的3倍。抽烟对30～40岁之间的男性生殖损害最大。
Killer One: Pollutants that pollute nitrogen oxides and lead in the air are killers of male reproductive issues. Scientists found that men who work or live near the freeway for more than 6 hours a day have significantly worse sperm quality than other men of the same age. Scientists in Hong Kong, China, find that seafood contains more mercury, a chemical that is harmful to reproduction, because of the industrial pollution of the oceans. Therefore, excessive consumption of seafood will make the blood mercury levels increased, leading to male infertility. Killer II: Smoking Men often smoke three times more than men who never smoke. Smoking is most prevalent in men aged 30 to 40 years.
