Abstract

The epididymal region of the domestic duck is composed by efferent ductules, whose histotopology was characterized by the proximal and distal ductules and sequentially by the epididymal duct. The epithelial lining of the efferent ductules was ciliated pseudostratified and formed by columnar cells. Also the ducts epididymidis epithelium was pseudostratified but non-ciliated. Concerning the histomorphometric analysis, the epithelial height mean was significantly greater in the distal efferent ductules, differing from the lower epithelium height mean observed in proximal efferent ductules and epididymal duct. The maximum and minimum diameter mean were significantly greater in the proximal efferent ductules, comparatively to the same diameter means of the other ductules.
