The male gonadal arteries, namely the testicular arteries, may vary at their origin and arise from the renal artery, suprarenal artery or lumbar artery. They may also be doubled, tripled or even quadrupled and may arise as a common trunk. With the advent of new intra-abdominal operative and laparoscopic techniques, the anatomy of the gonadal vessels has assumed much more importance. Therefore, a study was designed to assess the percentage of normal and aberrant origin and course of the testicular artery in the Indian population.
The posterior abdominal walls of 34 male cadavers (68 sides) were dissected and studied for the variations in the origin and course of the testicular arteries.
In 85.3 percent of the cases, the male gonadal artery was normal in origin, number and course. However, in the remaining 14.7 percent, various anomalies in the testicular artery were noted.
The variations in the testicular arteries are attributed to their embryological origin. A deep knowledge of these variations and their relations to the adjacent structures is very important in avoiding the complications in operative surgery.
男性性腺动脉，即睾丸动脉，其起源可能存在变异，可起自肾动脉、肾上腺动脉或腰动脉。它们也可能出现双支、三支甚至四支的情况，还可能以共同干的形式发出。随着新的腹部手术和腹腔镜技术的出现，性腺血管的解剖结构变得更为重要。因此，开展了一项研究，以评估印度人群中睾丸动脉正常及异常起源和走行的比例。
解剖34具男性尸体（68侧）的后腹壁，研究睾丸动脉起源和走行的变异情况。
85.3%的病例中，男性性腺动脉起源、数量和走行正常。然而，在其余14.7%的病例中，发现了睾丸动脉的各种异常情况。
睾丸动脉的变异归因于其胚胎学起源。深入了解这些变异及其与相邻结构的关系对于避免手术并发症非常重要。
