The cycle of the seminiferous epithelium and morphological features of spermatids in Crocidura dsinezumi were studied by light microscopy. The cycle of the seminiferous epithelium was divided into 12 stages. The dark type of spermatogonium(Ad) is appeared in all stages, and intermediate(In) in stage IV and B spermatogonium in stage V and VI were observed. The development of the acrosomal system, and changes in nuclear morphology of spermatids were divided into 14 steps. The Golgi, cap, acrosomal, maturation and spermiation phases were observed during steps $1{sim}2$, steps $3{sim}6$, steps $7{sim}10$, steps $11{sim}13$, and step 14, respectively. Our results provide the foundation for future studies of the spermiogenesis of Crocidura dsinezumis.
