Abstract

|
|
The aim of this study was to clarify the differentiation of seminiferous epithelial cells and spermiogenesis in the testis of Rana catesbeiana. Spermatogenesis of R. catesbeiana consists of primary spermatogonia, secondary spermatogonia, primary spermatocytes, secondary spermatocytes and spermatids. They were subdivided into eight stages on the basis of the morphological features of the germ cell differentiation. From the spermatocytes except primary spermatogonia to before the spermiation of spermatids were surrounded by spermatocyst. Spermiogenesis of R. catesbeiana can also be divided into three stages on the basis of morphological features of the nucleus and the cytoplasm organelles. Spermatozoon contained a saccular acrosome, a cylindrical and tapered slighty at both ends head, and a tail with only the axoneme.
