In this image you can see the spermatic chord extending away from the testes. Note the pampiniform plexus near the testes of the boar. The pampiniform plexus contains arteries and veins that supply and drain the testes. A counter-currrent exchange system occurs in the pampiniform plexus between arterial and venus blood. This exchange is responsible for high testosterone in testis and maintaining testisticular temperature.

The vas deferens, a component of the spermatic chord is also visible.
