[edit on Wikidata]
The tunica albuginea is a dense,[1][2] blue-white[3] layer of fibrous tissue surrounding the testis.[1][4] It is the middle of three envelopes forming the capsule of the testis; it is deep to the visceral layer of tunica vaginalis, and superficial to the tunica vasculosa testis (vascular layer of testis).[5]
The connective tissue of the tunica albuginea testis extends into the substance of the testis to form fibrous partitions - the septa testis.[1] At the posterior aspect of the testis (where the serosa of testis is deficient to allow for the attachment of the epididymis), the tunica albuginea extends into the testis to form the mediastinum testis.[5]
