What is the normal epididymal head diameter?

Explanation:
The normal epididymal head diameter is about 1 cm, with typical reported ranges around 0.8–1.2 cm. On scrotal ultrasound, you measure the widest part of the head in the transverse view. So a measurement of 1–1.2 cm sits within the normal range. This size helps distinguish a normal epididymis from conditions that can enlarge it, such as epididymitis or obstruction, or indicate atrophy if it’s smaller than expected.
