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.{{Cite book |last=Martini |first=Frederic |title=Human Anatomy |last2=Tallitsch |first2=Robert B. |last3=Nath |first3=Judi L. |publisher=Pearson |year=2017 |isbn=9780134320762 |edition=9th |pages=711}}
