The coati (Nasua nasua) belonging the order Carnivora and the family Procyonidae, does not configure the List of species in Brazilian fauna threatened of extinction from the Ministry of the Environment. On the contrary, its unstoppable population growth near urban areas has been causing economic, environmental and sanitary problems. The detailed study about reproductive characteristics of this species proves to be an important tool in reproductive biotechnologies application concerning to conservation as well as to its population control. The objectives on this work were to describe the stages of the seminiferous epithelium combining the techniques of tubular morphology method and acrossomic system method, besides determining the total duration of seminiferous epithelium cycle (SEC) with the incorporation of bromodeoxyuridine (BrdU). In this experiment six captive adult male animals were used. All six animals were used in the description of the stages, but only two were used in the measurement of SEC duration. The total duration of the seminiferous epithelium cycle in this species was calculated in 8,13 days and, as long as it takes approximately 4,5 cycles so that the whole spermatogenic process is complete, about 36,58 days are spent in the production of spermatozoa from a spermatogonia.
