Intratesticular ducts
Sperm pass from the seminiferous tubules into the rete testis, an interconnected system of channels located in the mediastinum. The rete, in turn, connect with about 20 efferent ductules, transporting sperm out of the testis and terminating at the duct of the epididymis in the head of the epididymis. 40x

Mediastinum

The rete, in turn, connect with about 20 efferent ductules, transporting sperm out of the testis and terminating at the duct of the epididymis in the head of the epididymis. 40x

Tunica albuginea
Sperm pass from the seminiferous tubules into the rete testis, an interconnected system of channels located in the mediastinum. The rete, in turn, connect with about 20 efferent ductules, transporting sperm out of the testis and terminating at the duct of the epididymis in the head of the epididymis. 40x

Seminiferous tubules - Convoluted portions
Sperm pass from the seminiferous tubules into the rete testis, an interconnected system of channels located in the mediastinum. The rete, in turn, connect with about 20 efferent ductules, transporting sperm out of the testis and terminating at the duct of the epididymis in the head of the epididymis. 40x

Duct of epididymis
Sperm pass from the seminiferous tubules into the rete testis, an interconnected system of channels located in the mediastinum. The rete, in turn, connect with about 20 efferent ductules, transporting sperm out of the testis and terminating at the duct of the epididymis in the head of the epididymis. 40x
