Abstract: The testis is the organ upon which the survival of the human species depends.
Abnormalities of testicular vessels may lead to loss of gametogenesis and hormone
production. Reported here is a case of bilateral variations of the testicular vessels
observed in a male cadaver during the first year MBBS dissection classes. The right
testicular vein bifurcated into two veins just before its termination and both the
branches terminated into the inferior vena cava. The left testicular artery arose
from the abdominal aorta just above the level of origin of the inferior mesenteric
artery. There was an arterio-venous anastomosis between the left testicular vein
and the left testicular artery. The arterio-venous anastomosis might be functionally
important as it can change the quality of the blood entering the testis.
