摘要 目的:为了解上游法、Percoll梯度离心法、Isolate密度梯度离心法等精子优化处理方法处理精液的质量。方法:我们选取124例女性原因引起的继发不孕的夫妇,将男方的精液标本随机分四组,每组各31例,分别为对照组,上游组、Percoll组及Isolate组。用DNA荧光染色精子动静态分析系统(简称荧光CASA)分析精子密度、a+b级、正常形态率和绿色荧光精子率。结果:三处理组富集的精子a+b级活力、正常形态率、绿色荧光精子明显高于对照组(P<0.01),Percoll组和Isolate组与对照组的精子密度无显著差异(P>0.05),但上游组与对照组相比精子密度明显降低(P<0.01);三处理组之间比较,获得的精子a+b级活力、正常形态率没有明显差异(P>0.05),但精子回收Percoll密度梯度离心法和Isolate密度梯度离心法明显高于上游法(P<0.01),Isolate密度梯度离心法富集绿色荧光精子最多,对精子损伤最小。结论:Isolate密度梯度离心法比上游法、Percoll梯度离心法处理精液效果好,在辅助生殖技术治疗中应优先选择。
