Epididymis: head
A higher magnification of an efferent duct shows its columnar epithelium, composed of tall and short cells, some with cilia and some with lysosomes. The variation in height imparts a scallopy border diagnostic for these tubules. The numerous lysosomes absorb and break down testicular fluid, while cilia help propel sperm through these tubules. 400x

Vasculature >
The numerous blood vessels present in the connective tissue surrounding the efferent ducts legitimizes the term “coni vasculosi.”

Sperm >
Sperm are present in the lumen of this tubule.
