(a): Overview of the epithelium of the caput portion, showing the principal cells (P), rich in vesicles (v) and Golgi complexes (gc). (b): Overview of the epithelium of the cauda region, with a clear cell (c), vesicles (v) and Golgi complexes (gc). (c): Narrow cell (N) of the cauda region, in cross section, showing a reduced amount of vesicles (v) and lipid drops (l). (d,e): Caput and cauda lumens, respectively, with sperm without abnormalities (arrowheads). l, lipids; n, nucleus; s: stereocilia.
