The epithelium lining of the epididymal duct is pseudostratified columnar and the cell population is comprised of principal, basal, and apical cells. The stroma periductal, is a well developed framework surrounding the tubule. Epididymal epithelial heights were maximal in the initial segment and minimal in the tail. Luminal diameter was just the reverse of the last pattern, e.g., it increased along the length of the duct.
