What does the tunica albuginea do?
The tunica albuginea (TA) envelops the penile erectile bodies and is composed of organized fibrillar collagen interlaced with elastin fibers, which allow tunica expansion. It protects erectile tissue, promotes penile rigidity and length, and participates in the veno-occlusive mechanism.
