定时曝光技术测定精子活动功能
诊法。即以接在目镜筒顶端的单镜头反光照像机慢速(定时)拍照显微镜内(用暗视野)精子活动情况的一种方法。用全色黑胶片或即时显影相纸,曝光时间定为1秒。每份样品取5个视野拍照,自每张照片中随机选取20个精子(或更多),按下列定义对精子运动轨迹进行分析和记录:①精子泳动方式:a旋转式:成对而连续的精子头点;b摆动式:连续弯曲的轨迹;c不 规则式:除上述之外的其他形式。②直线运动与非直线运动:a直线运动:不论泳动方式如何 ,运动轨迹的轴线是直线者为直线运动;b非直线运动:轨迹轴线弯曲。③线性速度:精子 在1秒钟内在X、Y轴上前进的距离,以μm/s表示。④精子摆动的宽度。⑤频率:精子在泳动时每秒摆动的次数。⑥快速运动:线性速度>25μm/s。以上述指标计算精子的平均线性速度Vs,摆动频率平均值F,摆动宽度平均值Ah,直线运动精子百分率和不同泳动方式精子百分率。本法全过程约需15~20分钟,简便、价廉、信息可靠。已证实在诊断男性生育力中是穿卵试验的补充,能对精子运动特征做进一步说明。
