In this species, the unrestricted or lobular type testes lining the caudal side of the body cavity are translucent and slender. Spermatogonia occur along the length of the tubules and the development of sperm takes place within cysts formed by Sertoli cells. Spermiogenesis involves preparatory morphological events followed by conspicuous modifications such as the movement of the centrioles, completion of the nuclear condensation, reduction of the cytoplasm, and the final differentiation of the flagellar complex. Mature spermatozoon has an oval nucleus, condensed chromatin, and typical 9 + 2 flagellar axoneme but lack acrosome. The role of the material in the nucleus and the cytoplasm as it reaches the Sertoli cell in the control of spermatogenesis is discussed. |
