RESUMO
The position and morphology of the male genitals of ten adult male pacas were studied; five especimens were fixed in aqueous solution of 10% formol and studied microscopically. From five especimens were collected fragments of these structures that after this usual proceeding to the inclusion in paraplaster and historesin they were analysed microscopically. Externally, we could identify the scrotum in the age of migration of testicle that presented structured parenchyma in seminiferous tubules which the basal menbrane reposed the germinative epithelium; these organs could be in the abdominal cavity or in the inguinal course. The fibroelastic male organ is located in the pubic region, in direction to tail, its gland, covered by keratinous epithelium was recovered by prepuce, under this we can find one thin cartilaginous structure with serried boards; one pair of osseous espícules were in the ventral sack until urethra which mucous was covered by epithelium of transition. The epidermal duct was covered by a pseudo- stratified epithelium and cubic simple, and it was coiled in the head, it was kept the body and the tail which one the referent duct originated, covered by pseudo- stratified epithelium columnar. The genital glandulas accessories: Vesicular, prostate, coagulative and urethral bulb, estructured like mucous glandulas emerging to pelvic urethra.
