Abstract

The hoary fox Lycalopex vetulus (Lund, 1842) is a small canid, endemic to Brazil, belonging to the Canidae family, widely distributed in the country, occurring records in different regions and habitats. The objective of this study is to describe morphologically the testicles and epididymal ducts of hoary fox. The animals, coming from the zoo of Federal University of Mato Grosso, Brazil, had died by natural causes. The male reproductive system was dissected to collect the testicles. The samples were fragmented and histologically examined. Microscopically, the testes were coated by the vaginal and albuginea tunic, formed by modeled dense connective tissue with large amount of collagen fibers. Into the organ, convoluted seminiferous tubules were surrounded by a basement membrane characterized by the presence of myoid and Sertoli cells and germinative epithelium composed by Between the seminiferous tubules, interstitial tissue composed of connective tissue, blood and lymph vessels and Leydig cells in polyhedral shape was present. The epididymal ducts showed pseudostratified columnar epithelium with secretory cells, in which stereocilia located on a basement membrane filled by myoid cells were found. The structures observed by us are very similar to those described for other mammals.
