A varicocele is an abnormal enlargement of veins in the pampiniform plexus which may hinder blood flow through the pampiniform venous plexus into the testicular vein. The reduced venous drainage and the resulting elevated testicular temperature may be caused by ______.
a. defective venous valves in the testis
b. elevated systemic arterial blood pressure
c. elevated core body temperature
d. reduced testicular arterial blood flow

It is network of small veins, that surrounds each testicular artery.In addition to its function in venous return from the testis,it also plays a role in the thermal regulation of the testis. It reduces the temperature by absorbing heat from the arterial blood, cooling it before it enters testis.
