what is different about the ruminant/boar penis?
- fibroelastic
- sigmoid flexure is post scrotal
- retractor penis is attached distal to the SF
dorsal apical ligament
thick longitudinal band slips off the dorsal surface of the tunica albuginea distal to the SF and insert back into t. albuginea near the apex where it fans out to encapsulate the head of the penis
- it is separated from the underlying t albuginea by a fascial layer
- penile deviated results from problems with the apical ligament

- foul smelling and pheromones
- corynebacterium suis
- if the penis enters during copulation -> infertility
