摘要
为探讨精液中白细胞与精液质量的关系，对１１例生育男性、１８例生殖道感染性不育及１６例特发性男性不育患者，分别进行精液常规分析、精液白细胞计数、ＭＤＡ测定、精子活力测定及精子细胞膜完整性的测定。结果显示：（１）生育组白细胞密度为７３．２±２９万／ｍｌ，显著低于感染组（１４６．１±９２．２万／ｍｌ）及弱精子症组（１１１．３±５３．４万／ｍｌ），同时精子活动率、ＳＶＴ、精子头部膜完整率、尾部膜完整率均显著高于其它二组；生育组精液中ＭＤＡ值为４．５９１±２．５２１ｎｍ／ｍｌ，显著低于不育组。死亡率显著低于其它二组。（２）相关分析显示ＭＤＡ与白细胞密度成正相关，与精子活动率、ＳＶＴ、膜完整率成负相关。研究结果显示：（１）精液白细胞可通过膜脂质过氧化反应对精子功能造成损伤；（２）膜脂质过氧化反应可伴随白细胞的增加而增加，但同时又受精液中ＳＯＤ的抑制。结论：在病理情况下，白细胞增多可通过ＭＤＡ导致精子运动力、活动率下降，精子膜完整性受损，从而使精子受精能力下降。
おn order to determine the relationship between seminal leukocyte and sperm function, we have studied 11 cases of fertile men and 18 cases infertile men with genital tract infection and 16 cases of idiopathic infertile men. The investigation includes seminal leukocyte, current semen parameters, SVT, membrane integrity, and seminal MDA. The results show: 1. Leukocyte is significantly higher in infertile group than in normal group. The sperm vitality, SYT and membrane integrity is significantly higher in normal group than in infertile group; 2. MDA has positive correlation to leukocyte and has negative correlation to sperm vitality, SVT and membrane integrity. In conclusion, with high concentration of seminal leukocyte, sperm motility and membrane integrity would be damaged and sperm function would be decreased.
