Where is the epididymis primarily located relative to the testis?

• A. Posterior surface
• B. Anterior surface
• C. Superior surface
• D. Lateral surface

Answer: (A)

The epididymis is positioned along the posterior surface of the testis, hugging the back edge as it curves from the superior pole downward toward the inferior pole. The head sits at the superior-posterior aspect, with the body and tail extending along the posterior border. This posterior placement is why the correct choice is the posterior surface, rather than the anterior, superior, or lateral surfaces. In ultrasound, you’ll typically see the epididymis as a band-like structure just behind the testis, continuous with the testicular hilum at the superior-posterior region.
