Spermatogenesis of the opossum (Didelphis azarae, Temminck, 1825) as revealed by the ferric hematoxylin technique is described. The spermiogenesis is subdivided in 15 steps characterized by changes observed in the nucleus and in the acrosomic structure of the spermatids. Using the morphological changes during the spermatids' maturation, a classification into 10 stages is proposed for the various cellular associations during the cycle of the seminiferous epithelium of the opossum.
本文描述了通过苏木精铁染色技术揭示的负鼠（Didelphis azarae，Temminck，1825）的精子发生过程。精子形成过程分为15个步骤，其特征是在精子细胞的细胞核和顶体结构中观察到的变化。利用精子细胞成熟过程中的形态变化，对负鼠生精上皮周期中不同细胞组合提出了分为10个阶段的分类方法。
