不同职业和吸烟对男性不育症患者精液质量的影响

Effect of occupations and smoking on semen quality of male infertility patients

目的探讨不同职业、吸烟等因素对男性不育症患者精液质量的影响。方法通过对不育症男性患者发放问卷调查,了解其年龄、职业、日吸烟量等生活习性。按照《WHO人类精液及精子-宫颈黏液相互作用实验室检验手册(第4版)》标准,采用计算机辅助精子分析(CASA),对不同从业者之间、吸烟者与无吸烟史者之间精子质量进行相关性分析。结果农民的精子密度与商业人员及职员相比明显偏低(P<0.05),但精子活率在各从业者之间没有明显差异。日均吸烟量在2包及以上者精子密度与无吸烟史者相比差异有统计学意义(P<0.05)。结论过量吸烟影响男性的生精功能,农民的精子密度较低。

Objective To explore the different occupations, smoking and other factors on the semen quality of the male infertility patients. Methods The infertility patients were surveyed for age, occupation, smoking, and living habits by questionnaire. According to the standards of WHO Human Semen and Sperm-Cervical Mucus Interaction Laboratory Manual （4th ed.）, the computer-assisted sperm analysis （CASA） was adopted, the correlation analysis of the sperm quality among the different practitioners, smokers and non-smokers were performed. Results Farmer＇s sperm density was obviously lower compared with that of businessman and staff （P〈0.05）, but sperm vitality had no significant difference among the different practitioners. There was the significant difference in the sperm density between the smokers with over 2 packets of cigarette and the people without smoking history （P〈0.05）. Conclusion Excessive smoking affects spermatogenesis in men, the sperm density is lower in farmers.
