The septa testis are fibrous partitions of the testis dividing the testis into compartments - the lobules of the testis. The septa are formed by extensions of the tunica albuginea - the dense fibrous connective tissue surface covering of the testis - into the substance of the testis. The septa converge towards the mediastinum testis.[1]
