Objective To investigate the relevance between semen quality and bad habits.Methods The clinical data of 262 cases of male infertility patients in our hospital from September 2011 to September 2014 were selected and retrospectively analyzed, divided into 5 groups according to the bad habits, a stay up group with 62 cases, drinking group with 46 cases, a smoking group with 50 cases, a sauna group 54 cases, a comprehensive group (more than 2 kinds of bad habits) with 50 patients, 50 cases without staying up late, drinking, smoking were selected as the control group. The sperm concentration and sperm morphology were compared between the study group and the control group. Results Sperm concentration in drinking group, sauna group and stay up group was significantly higher than that in the control group, the difference was statistically significant (P<0.05); the forward moved ability of sperm in control group was significantly higher than that in stay up group and smoking group, the difference was statistically significant (P<0.05); sperm morphology of the control group was significantly better than that in drinking group, smoking group, sauna group and comprehensive group, the difference was statistically significant (P<0.05).Conclusion Bad habits will determine the level of semen quality, sperm concentration for men, as well as the ability to affect the forward movement of sperm morphology is very large, so that men should pay full attention to their habits, to correct bad habits, in order to improve semen quality.%目的：探究男性精液质量与不良生活习惯的相关性。方法选取我院2011年9月～2014年9月期间收治的262例男性不育患者的临床资料进行回顾性分析，按不良生活习惯的类型将其分为5类：熬夜组62例，饮酒组46例，抽烟组50例，桑拿组54例，综合组(至少含以上2种不良生活习惯)50例，另选50例无熬夜、饮酒、抽烟以及桑拿的志愿者作为对照组。对比分析各组患者与对照组患者的精液密度及精子形态。结果对照组患者的精液密度明显高于饮酒组、桑拿组、熬夜组及综合组患者，差异具有统计学意义（P＜0.05）；对照组患者精子向前运动能力明显高于熬夜组、抽烟组及综合组患者，差异具有统计学意义（P＜0.05）；对照组患者精子形态明显优于饮酒组、桑拿组、抽烟组及综合组患者，差异具有统计学意义（P＜0.05）。结论不良生活习惯直接决定了男性精液质量的高低，对于男性精子密度、向前运动能力以及精子形态的影响非常大，所以，男性应当充分重视自身的生活习惯，纠正不良生活习惯，以此提高精液质量。
