Abstract: The spermatogenesis of the hairy armadillo was studied. Four spermatogonial types were identified: A+ (with PAS-positive granules, presumably the stem cell), A, In. and B—similar to the situation in the rat. Spermiogenesis could be subdivided into the four classical phases, comprising 14 steps of spermatid evolution. Eleven stages of the cycle are identified.
