The mediastinum testis is a network of fibrous connective tissue that extends from the top to near the bottom of each testis. It is wider above than below.[citation needed] It supports the rete testis and blood and lymphatic vessels of the testis in their passage to and from the substance of the gland.[1]
The septa testis - extensions of the tunica albuginea into the substance of the testis that form fibrous partitions - converge towards the mediastinum testis.[1]
