Spermiogenesis can be divided into several stages:
1. Golgi Phase: Spermatids begin to form the acrosomal vesicle. 2. Cap Phase: The acrosomal vesicle enlarges and flattens over the nucleus, forming the acrosomal cap. 3. Acrosome Phase: The spermatid elongates, and the acrosome covers the anterior half of the nucleus. 4. Maturation Phase: Final adjustments occur, including the shedding of excess cytoplasm and the formation of the flagellum.
