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.
