摘要
目的：探讨磁场对精子结构和功能的影响及其作用机理。方法：采用３种精子活力测定方法，研究不同磁场作用下精子的存活率、活动力和爬升力的变化，并运用透射电镜观察其超微结构改变。结果：受磁场作用，各实验组精子存活率、活动力和爬升力均明显低于无磁对照组；电镜显示实验组精子及其线粒体肿胀，精子细胞膜破裂。结论：在体外实验条件下。
Objective:The purpose of the research was to explore the effect of magnetic field on the structure and function of sperm and the mechanism through which the effect comes into existence.Methods:The moving and climbing ability and the vital rate of sperm under the action of magnetic field were examined,and the changes in sperm ultrastructure were studied by transmission electron microscope.Results:After magnetic field treatment,the moving and climbing ability and the vital rate of sperm in all experimental groups decreased obviously,while no changes were noted in control group.The transmission electron microscopic study showed that the sperm and its mitochondria were swollen and the membrane of some sperm was broken.Conclusion:Under certain experimental condition in vitro ,magnetic field in a given strength may induce ultrastructural and functional injury of sperm.
