精子染色质结构分析与精液参数的相关性研究

目的 :研究精子染色质结构分析 (SCSA)与精液参数的相关性 ,探讨评估精液质量的可靠方法。　方法 :将5 11份精液标本流式细胞术SCSA结果与精液常规分析结果进行多参数的相关性分析。　结果 :与变性精子百分数(COMPαt)呈低度正相关 (r在 0 .10～ 0 .3 0 )的参数是粘度、本次射精间隔时间、精子畸形率、c级精子密度 ;呈低度负相关的参数 (r在 - 0 .3 0～ - 0 .10 )是曲线速度、直线速度、平均路径速度 ;呈中度正相关 (r在 0 .3 0～ 0 .70 )的参数是精子密度、d级精子率和d级精子密度 ;呈中度负相关 (r在 - 0 .70～ - 0 .3 0 )的参数是平均移动角度、a级精子密度和精子存活率。　结论 :流式细胞术能简单、快速、准确地评估损伤和变性精子的百分数 ,其结果 (COMPαt)与精液参数部分相关 ,并不是完全独立于精液常规检查的指标。SCSA对评估生育力具有重要意义

Analysis of Correlation Between Parameters of Sperm Chromatin Structure Assay and Semen Routine Analysis

OBJECTIVES: To analysis the correlation between parameters of sperm chromatin structure assay(SCSA) and semen routine analysis, and to discuss the reliable methods of semen quality evaluation. METHODS: Five hundred and eleven semen samples were detected to analyse the mutiple-parameter correlation between results of SCSA (COMP alpha t) and semen routine analysis. RESULTS: The parameters that have low-level positive correlation(r: 0.10-0.30) with denatured sperm percentage(COMP alpha t) were viscosity, ejaculation interval, abnormal sperm ratio, concentration of grade c sperm; those having low-level negative correlation(r: -0.30(-)-0.10) were VDL, VSL and VAP; those having mid-level positive correlation (r: 0.30-0.70) were sperm concentration, percentage of grade d sperm; those having mid-level negative correlation (r: -0.70(-)-0.30) were MAD, percentage of grade a sperm and survival rate. CONCLUSIONS: Flow cytometry can be used to evaluate the percentage of denatured or injured sperm rapidly, correctly and simply. The result (COMP alpha t) correlates partly with semen parameters, and it is not a conclusively parameter compared with routine semen analysis. It is important to use SCSA to evaluate productivity under the above situation.
