精子形态学参数与精子活力的关系

摘要

Objective: To investigate the relationship between sperm vigor and sperm morphology parameters. Methods: The sperm specimens of 6 725 cases with male infertility were stained by Diff-Quik to analyse their morphologies. Results: The percentage of normal sperms in morphology with normal vigor was significantly higher than that of the sperms with abnormal vigor(P < 0. 01) . The percentage of head, midpiece and tail faults and the index of deformity sperm of sperms with normal vigor were significantly lower than those of the sperms with abnormal vigor( P < 0. 01) . Conclusions:The percentage of normal morphology and head,midpiece and tail faults and the index of deformity sperm of sperms are strongly linked to their vigor,which can be used as an important parameter of male fertility.%目的:探讨精子形态学与精子活力参数的关系.方法:对6 725例男性不育患者精液标本进行常规检查,并用Diff-Quik法染色进行精子形态学分析.结果:精子活力正常组的正常形态精子百分率明显高于精子活力异常组(P<0.01);精子活力正常组精子头部缺陷率、精子中段缺陷率、精子尾部缺陷率、畸形精子指数(TZI)及精子畸形指数(SDI)均低于精子活力异常组(P<0.01).结论:正常形态精子百分率、精子头部缺陷率、精子中段缺陷率、精子尾部缺陷率、TZI及SPI与精子活力有密切关系,并可作为临床评价男性生育力的重要指标.
