Which structure contains the rete testis?

• A. Epididymis
• B. Tunica albuginea
• C. Mediastinum testis
• D. Rete testis

Answer: (C)

The rete testis is a network of channels located in the mediastinum of the testis—the central, supportive region inside the testicular parenchyma. From the seminiferous tubules, the tubules become straight (tubuli recti) and drain into this network, which then leads to the efferent ductules and onward to the epididymis. Because of this placement, the structure that contains the rete testis is the mediastinum testis. The other structures serve different roles: the epididymis harbors the epididymal ducts and stores sperm; the tunica albuginea is the tough capsule surrounding the testis; the rete testis itself is the network within the mediastinum, not the container.
