The head of the epididymis receives spermatozoa via the efferent ducts of the mediastinium of the testis. source
The head of the epididymis receives spermatozoa via the efferent ducts of the mediastinium of the testis.
The head of the epididymis is characterized histologically by a thin myoepithelium. The concentration of the sperm here is dilute. source

In reptiles, there is an additional canal between the testis and the head of the epididymis and which receives the various efferent ducts. source

The epididymis is covered by a two layered pseudostratified epithelium. source

The epithelium is separated by a basement membrane from the connective tissue wall which has smooth muscle cells. source

Main cells: columnar cells that, with the basal cells, form the majority of the epithelium. source

The stereocilia in the epididymis are shaped by an internal actin network with no microtubule structure, and unlike true cilia are non-motile. source

Sperm are initially nonmotile as they leave the seminiferous tubules, large volumes of fluid are secreted to propel them to the epididymis. source

This absorption creates a fluid current that moves the immobile sperm from the seminiferous tubules to the epididymis. source

The epididymis develops from tissue that once formed the mesonephros, a primitive kidney found in many aquatic vertebrates. source

Persistence of the cranial end of the mesonephric duct will leave behind a remnant called the appendix of the epididymis. source

An inflammation of the epididymis is called epididymitis, it is much more common than testicular inflammation, termed orchitis. source
