Unilateral Double Left Testicular Vein with Aberrant Testis: An Intriguing Anatomical Tale

Knowledge regarding the variations of the gonadal veins is of great clinical importance due to the increasing trends of invasive interventions such as laparoscopic and transplant surgeries. Typically, the right gonadal vein enters the inferior vena cava directly and the left gonadal vein terminates in the left renal vein. Both veins may be replaced by multiple vessels in the lower abdomen and occasionally remain double as far as their termination. During routine dissection of a 50-year-old male cadaver, a duplicated left testicular vein along with sigmoid shape left testis, was observed. Both the left testicular veins were draining into the left renal vein at a straight angle. The right gonadal vein followed the typical pattern. The histopathological findings indicate azoospermia as only Sertoli cells were observed in the microscopic section of testes. The above variations may remain unnoticed until discovered during surgery or autopsy. Such variations might increase the possibility of varicocele and infertility in patients? Hence, in-depth knowledge of these developmental anomalies of the gonadal veins is of great importance. The prehand knowledge of such variations may be useful during renal transplantation, renal and gonadal surgeries, and other therapeutic and imaging diagnostic procedures.
