TYPES OF PENIS
1. Fibroelastic
Found in: Bull, Boar, Ram, Deer.
->Contain large amounts of connective tissue and elastic fibres but limited erectile tissue.
->Contain a sigmoid flexure
->They are encased by a non-expandable connective tissue sheath called the tunica albuginea.

Therefore, erection only results in increased length of penis and no increase in diameter of the penis. However, most of the increase in penile length is actually due to the straightening of the sigmoid flexure.
The cavernous tissue contains small blood spaces which means that only a small increase in blood to the penis is require to achieve erection.
2. Musculovascular
Found in:
Man, Stallion, Dog, Tom Cat
This penis structure contains a lot of erectile tissue and little connective tissue so during erection there is both an increase in length and diameter of the penis.

The cavernous tissue contains large blood spaces divided by thin septa. Therefore, a relatively larger volume of blood is required to achieve erection.
