通过显微镜检查和特殊染色技术的进一步鉴别,从而使精子体部和尾部的缺陷有了新的分类:第一级缺陷是染色异常和轻微的结构缺陷,第二级是精子尾部断裂或卷曲和第三级是仅存精子终端的退化原基。第一级染色异常的特性是对巴氏技术的多色染色和Shorr技术猩红色染色不起作用。虽然大多数精子形态未发生畸变,但必须认为是完全不活动的。 Further identification of microscopic examination and special staining techniques led to a new classification of sperm defects in the body and tail: first-degree defects were dysplasia and minor structural defects, second-level slippage or curling of sperm tail and Three is the only remaining sperm terminal degeneration of the original base. First-stage staining abnormalities are non-functional for multicolourization of Papanicolaou and Shorr-technique scarlet staining. Although most sperm morphology does not distort, it must be considered as completely inactive.
