The phenomenon of tail coiling in human spermatozoa is demonstrated by means of some clinical cases. The coiling of the free tail below the head is differentiated from the coiling of the axonema around the head and within a cytoplasmic droplet. The first phenomenon is caused probably by exogenous factors outside the testes such as pH-value and chemical constitution of the fluids in the seminiferous pathway; the latter may be caused genetically. The morphological alterations concern mainly the axonema in the tail and the organization of the middle piece and the head. Possible causes for the symptom of the coiled tail in spermatozoa are discussed.
通过一些临床病例证明了人类精子尾部卷曲的现象。头部下方游离尾部的卷曲与轴丝在头部周围以及在细胞质滴内的卷曲是有区别的。第一种现象可能是由睾丸外的外源性因素引起的，如生精管道中液体的pH值和化学成分；后者可能是由遗传因素导致的。形态学改变主要涉及尾部的轴丝以及中段和头部的结构。文中讨论了精子尾部卷曲症状的可能原因。
