*The '''Testicular Artery''' a direct branch off the aorta. This has important implications when performing castration procedures as the pressure within the artery will be very high and so it is imperitive to tie the artery off properly.

**The testicular artery is highly convoluted and contains many elastic fibres within its wall. It acts as a pulse pressure eliminator between the inguinal ring and surface of the teste, minimising the differance between systolic and diastolic pressures within the artery (usually 40mmHg).
*The '''Pampiniform Plexus'''

**The network of testicular veins that surround the testicular artery providing the testes with a countercurrent heat exchanger.
