Transmission electron microscopy shows five distinct cell types: light, dark, and angular non-ciliated cells with possible apocrine secretory role cells and halo cells, possibly intraepithelial leucocytes. The proximal efferent ductules have the widest diameter among all ductules in the epididymal region.247-255engArtigo10.1002/(SICI)1097-4687(199912)242:3<2472-s2.0-0033486262
