This work presents a comparative review about the spermatogenic process in cats (Felis domestica), jaguars (Panthera onca) and cougars (Puma concolor), with emphasis on testicular biometry, gonadossomatic index, volumetric proportion of testicular parenchyma components, tubular diameter, seminiferous epithelial height and seminiferous tubule length. It was an approach of the differences among the cell proportions that allowed conclusions about the overall yield of spermatogenic process and Sertoli cell index in three feline species.
