[Scanning electron and light microscopic studies of the surface epithelium of the rete testis and epididymis in the boar. II. Ductus epididymis].
The entire ductus epididymidis is characterized by pseudostratified columnar epithelium which contain principal and basal cells. Apical cells are found in the proximal segments. Long stereocilia projected from the apical surface of the principal cells. Signs of adjacent apocrine secretory activity are shown. The various segments of the ductus epididymidis present differences in the height of the epithelium, the development of the stereocilia, the appearance of granules in the cytoplasm, the luminal sperm concentration and the height of the peritubular layer.
