To investigate the process of spermoigenesis and glycogen effect during the spermatogenesis of Rana catesbeiana, the morphological characteristics of the testes were examined by light and transmission electron microscopy. Spermiogenesis of R. catesbeiana was divided into three stages on the basis of the features of the nucleus and the cytoplasm organelles. Except for the primary spermatogonia, the phases from the spermatocytogenesis to the spermatids before spermiation phase were surrounded by spermatocyst. Especially , the glycogen particles were not observed until in the stage of spermatocytogenesis, but from the early spermatids to the maturation phase were observed in the nucleus, acrosome and cytoplasm of the spermatids. The present result suggests that the glycogen may play an important role in the sperm maturation, and as a source of the energy in the wave-movement of sperm tail.
