摘要

Maintenance of testicular temperature below body temperature is essential for the process of spermatogenesis. This process of thermoregulation is mainly achieved by testicular veins through pampiniform venous plexus of the testis by absorbing the heat conveyed by the testicular arteries. However, this mechanism of thermoregulation may be hampered if an abnormal communication exists between the testicular vessels. We report herewith a rare case of arteriovenous communication between testicular artery and testicular vein on left side. The calibre of the communicating vessel was almost similar to left testicular artery. Such abnormal communication may obstruct the flow of blood in the vein by causing impairment in the perfusion pressure with the eventual high risk of varicocele.
