ABSTRACT
In the present study some aspects of the ultrastructure of sperm head differentiation in the Arabian horned viper Cerastes cerastes, were described. These include the development of the acrosomal vesicle, aggregation of the acrosomal granules, formation of the subacrosomal nuclear space, nuclear elongation and the role of microtubules manchette. The manchette participates in nuclear shaping and organelle movement. During head differentiation the fine granular chromatin of early spermatid is gradually replaced by highly condensed contents. The chromatin material condenses into a curved elongated head of the full-differentiated sperm.
