Abstract

We have studied the ultrastructure of testes biopsies and immotile spermatozoa from a supposed secondary infertile male. A wide range of tail defects has been described in testes and semen. Among these, tail stump spermatozoa occurs rarely. Although the origin of this defect is unknown, testes sections revealed that damage occurs during spermiogenesis at the latest stages during flagellum elongation in spermatids.

摘要

我们研究了一名疑似继发性不育男性的睾丸活检组织和不动精子的超微结构。在睾丸和精液中已描述了多种尾部缺陷。其中，尾部残端精子很少见。尽管这种缺陷的起源尚不清楚，但睾丸切片显示，这种损伤最晚发生在精子发生过程中精子细胞鞭毛伸长的最后阶段。
