1精液叶酸、维生素B_(12)、活性氧水平与精子质量关系研究显示文摘目的 : 检测人精液叶酸、维生素 B12 ( VB12 ) ,及活性氧 ( ROS)的含量 ,探讨三者与精子质量的关系。方法 : 收集经证实配偶已怀孕的新加坡籍健康成年男性 1 76名的精液 ,根据WHO推荐方法检测精子质量各项指标 ,并测定精液叶酸和 VB12 含量及 ROS水平。结果 : 平均精液量、精子浓度和其活力都在正常范围内。而精子存活率 ( 73.0 6% )略低于 WHO标准 (≥ 75% ) ,形态异常的精子 ( 77.0 6% )高于 WHO标准 ( 70 % )。精液的叶酸含量与 ROS水平呈显著负相关 ( r=- 0 .2 5,P=0 .0 0 3) ;VB12 与 ROS呈负相关 ( r=- 0 .2 5,P=0 .0 0 2 ) ,与精子形态异常也呈负相关( r=- 0 .1 5,P=0 .0 4 8) ,但与精子浓度呈正相关 ( r=0 .31 ,P<0 .0 0 1 )。ROS与精子形态异常呈正相关 ( r=0 .2 5,P=0 .0 0 2 ) ,与精子活力也呈正相关 ( r=0 .1 9,P=0 .0 1 9)。结论 : VB12 对精子生成和维持精子正常功能是必需的 ,ROS水平与精子功能缺陷有关 ,VB12 和叶酸可能通过降低 ROS以维持精子的正常功能。陈起萱 梅节 V Ng SE Chia 凌文华 CN Ong 2001营养学报2001,23,2:2
