摘　　要：目的：研究Percoll梯度离心后精子运动轨迹的变化。方法：Percoll梯度离心法处理精子运动状况较差的精液标本，分析精子运动轨迹的变化。结果：在24例精液标本中，Percoll处理前后的精子平均运动速度分别为18.4±4.6μm／s和25.7±5.4μm／s.二者之间具有显著差异（P＜0.01）。结论：用Percoll梯度离心法处理精子，可提高精子运动速度，改善精子质量。Objectives:To study change on motive tracks of sperm after Percoll gradient centrifugation. Methods: Semen samples for worse motion of sperm was treated by Percoll gradient centrifugation,and change on motive tracks of sperm was analyzed. Results :In 24 semen samples,mean Velocitys of sperm were 18. 4±4. 6μm/s and 25. 7 ±5. 4μm/s, so it was significantly differnet (P<0. 01 ). Conclusions: Percoll gradient centrifugation may enhance motive velocity of sperm and improve qualityof sperm.
