摘要
目的：了解现阶段天津市具有正常生育力健康男性的精液质量，探讨影响精液质量的因素。方法：以《世界卫生组织人类精液分析实验室技术手册》（第4版）为依据，使用奥林巴斯BX40相差显微镜检测天津市120例具有生育力的健康志愿者（19-38岁，在3个月内使性伴侣或配偶妊娠或子女年龄≤1岁的有生育能力男性志愿者）的精液质量，分析年龄、禁欲时间以及吸烟、饮酒、饮茶或咖啡对精液质量的影响。结果：①120例具有生育力的男性精液质量肉眼观察正常，其中17例（14．17％）精子密度〈20x106个／mL；6例（5．00％）精子存活率〈50％；20例（16．7％）精液不完全符合标准。②志愿者中不同年龄、吸烟量、饮酒程度、禁欲时间组间精子a＋b级活力、精子存活率以及精子密度、pH值差异无统计学意义（P〉0．05）。③经常喝咖啡与不经常喝咖啡组的精液pH值差异有统计学意义（P〈0．05），而精子a＋b级活力、精子存活率以及精子密度等参数差异无统计学意义（P〉O．05）。④经常喝茶与不经常喝茶组的精子密度比较差异有统计学意义（P〈0．05），而精子a＋b级活力、精子存活率等参数比较差异无统计学意义（P〉0．05）。结论：120例男性精液质量基本符合世界卫生组织（wH0）规定参考值标准，尽管少量精液不完全符合WHO参考值，f旦并不影响其生育力。本研究发现，年龄、禁欲时间以及吸烟、饮酒对精液质量无明显影响。经常饮茶可降低精子密度，经常饮用咖啡影响精液pH。
Objective： To study the semen quality of healthy and fertile men in Tianjin, and explore the factors affected semen quality. Methods： Semen assay was conducted on the World Health Organization＇s manual on semen analysis （4th）.The Olympus BX40 differ microscope was used to detect semen quality of 120 fertile and healthy men aged 19 to 38 years. They had children within age of 1 year or let their sexsual partner pregnancy within 3 months. Those factors including age, educational level, abstinence time, marital status , drinking, smoking, drinking tea or coffee were analysed. Results：①perm density of 17 （14.17%） men was 〈 20xl06/mL. The sperm survival rate of 6 （5.00%） men was 〈 50%. The semen quality of 20 （16.7%） men did not fully meet the standard.②here were not significantly difference in those semem paramenters among men with different ages, different abstinence time, with or without drinking or smoking （P〉0.05）.③emen PH value was significantly different between men drinking coffee and men no drinking （P〈0.05）. ④perm density was significantly different between men drinking usually tea and men drinking infrequently tea （P〈0.05）.There were not significant differences （P〉0.05） in those parameters such as grade （A＋B） sperm rate and viability rate between two groups. Conclusions： Few parameters of semen quality could not meet the index of WHO 4th manual in 120 fertility men. Age and abstinence time are not the risk factors of semen quality, but drinking usually tea affect sperm density and coffee affect semen pH.
