Ductulus Efferen
Spermatozoa pass through
- tubuli recti (low columnar epithelium)
- rete testis (flattened or cuboidal epithelium)
- ductuli efferentes (lined by a columnar epithelium)
which consists of both absorptive and ciliated cells. The height of the two cells types which form the epithelium of the ductuli efferentes is variable which gives the lumen a characteristic wavy outline.
The ductuli efferentes leave the testis and open into a common duct, the ductus epididymidis (about 6 m long!). It is lined by a very tall pseudostratified columnar epithelium. Most cells of the epithelium, also called principal cells, have long stereocilia. Stereocilia are non-motile structures, which in the EM resemble large microvilli. Towards the basal lamina we see a number of small nuclei, which belong to the basal cells of the ductus epididymidis. These cells regenerate the epithelium.
