What is the tunica albuginea and how does the trainer affect my erection?
Tunica albuginea: The whitish membrane within that surrounds the spongy chambers (corpora cavernosa) in the penis and which helps to trap the blood in the corpora cavernosa, thereby sustaining erection. The term comes straight from the Latin tunica (“covering” or “coat”) + albuginea (“white”) = a covering that is white, like the white (albumen) of an egg. It is the elasticity and overall size of the tunica albuginea that determine the length and the width of the penis.
