Epididymis

Notes

The epididymis is a long (4 - 5 meters), highly coiled tube, along which sperm mature as they move from the testis to the vas deferens.  This tube is surrounded by smooth muscle and embedded within a loose, vascular stroma.  Smooth muscle becomes thicker as the duct approaches the vas.

The lumen of the epididymal duct contains spermatozoa and is lined by a pseudostratified columnar epithelium with apical stereocilia.

The epithelium of the epididymal duct is similar to that lining the vas deferens.
