Testicular arteries are the main blood supplier for testes. Knowing the anatomy, relation and especially variations of them is critical
for surgical procedures such as varicocelectomy and kidney transplantation. Most of the case reports of anatomical variations focus
on morphological features, embryological background and in some cases following clinical problems but the effect of anatomical
variations on the physiological characteristics of the target organ have been ignored. What we are trying to emphasize is that
introducing a relation between the testicular artery variations and function of the testis as a target organ.
