“饭后一根烟，赛过活神仙”，商报网络问卷调查显示，超五成网友在要孩子前仍不戒烟。但是，最近有科学研究表明，父亲吸烟所导致的受损精子细胞DNA会遗传给下一代，增加孩子患癌症的风险。

"A smoke after a,Excel to live fairy",Business network questionnaire survey,Super fifty percent net friend in children before still don't quit smoking.but,Recent scientific research suggests that,Father smoking caused damage sperm cell DNA will pass on to the next generation,Increase the child cancer risk.

　　婚后3年，迟迟没有生育。今年1月份，毛军夫妇在郑州市妇幼保健院检查，结果显示，毛军的精子成活率不足40%，而正常的精子成活率要70%以上。

　　吸烟会损伤精子细胞DNA Smoking can damage the sperm cell DNA

　　据英国《每日邮报》报道，英国布拉德福德大学研究人员，通过对6000余人长达40年的追踪调查发现，父亲吸烟所导致的受损DNA会遗传给下一代，增加孩子患癌症的风险。

According to the British[Daily mail]reports,British researchers at the university of Bradford,Based on more than 6000 people for 40 years of tracking survey found,Father smoking caused by the damaged DNA will pass on to the next generation,Increase the child cancer risk.

　　研究人员测试了参试妻子怀孕前后，丈夫血液和精液的基因变化情况，并对产妇分娩时的脐带血进行了分析。结果发现，吸烟会造成男性精子细胞DNA损伤，而受损基因会遗传给下一代，增加儿童患癌症的风险，特别是白血病。

The researchers tested tested before and after the wife's pregnancy,Husband blood and semen genetic changes,And the maternity of umbilical cord blood is analyzed.The results showed that,Smoking can cause the male sperm cell DNA damage,And the damaged genes will pass on to the next generation,Increase a child's risk of cancer,Especially leukemia.

　　在郑州市妇幼保健院优生遗传科徐广立博士看来，男士吸烟会对生育造成负面影响是不争的事实。“尼古丁等有害物质通过血液循环进入睾丸，使其生精功能减退，生产出来的精子数目减少、质量降低。”他说，临床上因吸烟造成生育障碍的病人非常多见。男士长期吸烟，容易造成精子畸形，每天吸烟21-30根者，畸形精子发生率显著增高；吸30根以上者，畸形精子发生率更高。

In zhengzhou city maternal and child care service centre prepotency families XuGuangLi seems to dr,Man smoking can cause negative effect on bearing is an indisputable fact."Nicotine and other harmful substances through the blood circulation into the testes,Make its to give birth to fine hypothyroidism,Production out of a reduction in the number of sperm/Quality to reduce."He said,Clinically because of smoking cause birth disorder of patients is very rare.Man long-term smoking,Easy to cause the sperm deformity,Smoking every day 21-30 root person,Sperm malformation rate increased significantly;Suction 30 root more,Sperm malformation rate higher.

　　他认为，受到损伤的精子细胞DNA传给新生命，是非常危险的。“男士精子完全成熟需要90天，因此在要孩子之前，男士至少要戒烟3个月。”

He thinks,Damage sperm cell DNA to new life,It is very dangerous."Man fully mature sperm to 90 days,So in children before,Men were going to give up smoking at least 3 months."

　　他提醒，戒烟同时，要多吃水果、蔬菜，而大量饮酒、经常熬夜和久坐不动、高温作业，也是导致精子缺陷的“杀手”。(河南商报记者逯彦萃)
