Abstract

In addition to the common features of spermiogenesis in Reptilia, new structures are seen in Agama adramitana that have not been described in previous studies. Two acrosomal granules are observed in the acrosomal vesicle. The posterior acrosomal granule differentiates as an anterior electron-dense material in the acrosome, and the anterior one forms a posterior translucent component of the acrosome. Also, the subacrosomal granule spreads in the subacrosomal space as a subacrosomal nuclear cap.
