摘 要:目的探讨睡眠时间对精液参数、精子形态以及精子DNA完整性的影响。方法对581名男性的睡眠情况进行问卷调查,将其分为三组,即Ⅰ组,正常睡眠组;Ⅱ组,轻度睡眠缺乏组;Ⅲ组,严重睡眠缺乏组。采用计算机辅助精液分析系统(CASA)检测精液密度、活力、前向运动率等常规参数;采用Diff-Quick染色法分析精子形态;采用精子染色质扩散实验(SCD法)分析精子DNA完整性。结果Ⅰ、Ⅱ、Ⅲ组精液密度(70.5±14.2、65.7±11.2、53.8±12.6)×106/ml、活力(74.3±10.1、70.5±14.5、65.8±12.8)%、前向运动率(57.2±9.5、54.5±11.3、48.3±13.7)%均呈下降趋势,差异有统计学意义(P<0.01),并且Ⅱ、Ⅲ组精子畸形率(91.0±20.5、94.1±21.7)%和精子DNA碎片指数(17.5±10.1、24.6±11.7)%与Ⅰ组(86.4±18.3、16.8±9.5)%相比较,差异有统计学意义(P<0.05)。结论睡眠时间影响男性精液质量,可能是导致男性精液质量下降的因素之一。Objective To explore the effect of sleep time on human sperm parameters, morphology and sperm DNA integrity. Methods Five hundred and eighty-one men were divided into three groups according to their sleep status investigated by ques- tionnaires : Group I ( normal sleep group ) , Group II ( mild sleep deprivation group ) and Group III( severe sleep deprivation group ). The sperm concentration, motility and progressive motility were detected by computer-assisted sperm analysis system ( CA- SA). The sperm morphology was analyzed by Dill-Quick staining and the sperm DNA integrity was measured by sperm chromatin dispersion assay. Results From Group I to Group III, the sperm concentrations ( ( 70.5± 14.2 ) × 10^6/ml, ( 65.7±11.2) × 10^6/ ml, ( 53.8±12.6) × 10^6/ml ), motility ( ( 74.3±10.1 ) %, ( 70.5± 14.5 ) %, ( 65.8± 12.8 ) % ) and progressive motility rates ( ( 57.2 ±9.5 ) %, ( 54.5±11.3 ) %, ( 48.3±13.7 } % ) showed a declining tendency, with statistically significant differences ( all P〈0.01 ). Moreover, the sperm deformity rates ( ( 91.0±20.5 ) %, ( 94.1 ±21.7 ) % ) and sperm DNA fragmentation indexes ( ( 17.5± 10.1 ) %, (24.6±11.7)%) of the Group II and III showed statistically significant differences compared with those of Group I (( 86.4± 18.3) %, (16.8±9.5) % ) ( both P〈0.05 ) . Conclusions Sleep time affects the semen quality of males, and it may be one of the factors leading to decline in semen quality.
