Electron Microscope Study of Lizard Spermiogenese inTropidurus Torquatos(Lacertilia)

Abstract
In the course on an investigation on lizard spermiogenesis, we have observed events connected with the differentiation of the acrosome and middle-piece of the spermatozoa. Some differences from other reptilians were found as well as: the presence of a subacrosomal space, the absence of the fibrous sheath in the middle-pice and a very short neck in the mature spermatozoa.
