摘要
目的探讨反映精子质量的两个重要参数精子浓度及活力对精子冷冻复苏率的影响。方法回顾性分析了1624例供精者捐献的14190份精液标本，以了解精子浓度及活力对精子冷冻复苏率的影响。结果精子冷冻复苏率随着精子浓度的升高而明显增加，相关性分析发现精子浓度与精子冷冻复苏率呈正相关；冷冻前精子活力影响精子冷冻复苏率，精子活力＜50%组精子冷冻复苏率（66.5±20.4）%明显低于精子活力50%-60%组及精子活力＞60%组精子冷冻复苏率，而精子活力50%-60%组的精子冷冻复苏率[（69.2±16.3）%]与精子活力＞60%组[（69.0±13.3）%]比较，差异无统计学意义。结论冷冻前精子浓度及活力均可以影响精子冷冻复苏率，通过这两个指标预测精子冷冻复苏后的结果是可行的。
Objective To study the influence of sperm concentration and progressive motility on the recovery rate of human frozen spermatozoa. Methods The sperm concentration, progressive motility and the recovery rate after frozen-thawed process of 14190 semen samples were retrospectively analyzed. Results The sperm recovery rate increased significantly as the sperm concentration increased. The sperm recovery rate was positively correlated with the sperm concentration. The sperm progressive motility before freezing also affected the post-thawed sperm recovery rate. The post-thawed recovery rate （66.5±20.4）%in the group with sperm motility〈50%was lower than that of group with sperm motility from 50%to 60%（69.2±16.3）%and group with sperm motility〉60%（69.0±13.3）%, （P〈0.05）. But no statistical difference was found in recovery rate between the latter two groups. Conclusion Both of sperm concentration and progressive motility could be indicators for the recovery rate of human frozen spermatozoa.
