Structure/Morphology
There are approximately up to 20 efferent ductules of the testis, which are dispersed throughout the hilum of the testis (Standring, 2016).

Key Features/ Anatomical Relations
The efferent ductules are surrounded by a thin circular coat of smooth muscle. They are lined by ciliated columnar epithelial and non-ciliated endocytic cells (Standring, 2016).
Function
The efferent ductules of testis connects the rete testis to the head of the epididymis, allowing immature sperm to enter the epididymis.

Testis
Testis is the male gonad containing two functional parts: the seminiferous tubules for the production and transport of male germ cells (spermatogenesis) and the interstitial compartment containing Leydig cells that produce androgens.
