不育夫妇中精于因素占一定比例,治疗方法诸多,但都必须建立在精子具备授精能力的基础之上。因此检验精于是否具有授精能力是极重要的。以前采用精子穿透去透明带金黄地鼠卵试验。现所述的半透明带结合试验(HZA)是采用人卵在近于生理状态下检验精子受精能的方法。原理:受精的第一步是精子头部与卵透明带结合。不同的卵其成熱度不同,因此用显微切割的方法将卵透明带切成两半,一半用于被检测的精子,另一半则用于以体外受精-胚胎移植(IVF-ET)证实有良好的受精能力的正常精子。因此半透明带结合试验提供了完全同一的结合条件,比较两组精 Infertility couple in a certain proportion of factors, a lot of treatment, but must be based on the ability of sperm to have insemination. Therefore, it is very important to check if you have the ability to inseminate. Previously used sperm penetration to the transparent hamster golden egg test. Now the translucent band binding test (HZA) is the use of human eggs in nearly physiological state test sperm fertilization method. Principle: The first step in fertilization is the combination of sperm head and zona pellucida. Different eggs have different degrees of heat, so the zona pellucida is cut in half using half a cut, one half for the sperm being tested and the other half for IVF-ET Good sperm ability to fertilize. Therefore, the translucent band binding test provides exactly the same binding conditions, comparing two sets of precision
