Three parts can be distinguished: 1. The acrosome is composed of a thick electron-dense wall and a less electron-dense subacrosomal space. The nucleus is polymorphous. Depois da retirada da gonada masculina, pequenos fragmentos foram preparados para visualizar;ao de suas estruturas microsc6picas sob microscopia eletronica.
