Histomorphological studies on the testicular capsule of crossbred Large White Yorkshire boars (Sus scrofa domesticus)

The present study was conducted on the testes of six healthy adult Large White Yorkshire pigs. Parenchyma of testes of adult boars was surrounded by a thick fibrous testicular capsule composed of inner tunica vasculosa, middle tunica albuginea, and outer visceral layer of tunica vaginalis. Tunica vasculosa was prominent and characterised by loose connective tissue contained numerous blood vessels. Tunica albuginea was composed of irregular connective tissues madeup of collagen, elastin and reticular fibres. Visceral layer of tunica vaginalis was found as outer thin layer of testicular capsule comprised of mesothelium and connective tissue layer. Connective tissue layer was blended with underlying connective tissues of tunica albuginea.
