Testicular arteries

Last revised by Assoc Prof Craig Hacking on 02 Sep 2020

The testicular arteries (also known as the spermatic arteries) are the long, small-diameter gonadal arteries in the male that supply the testis alongside the cremasteric artery and the artery to the ductus deferens

Gross anatomy


As paired structures they arise symmetrically, slightly anteriorly from the aorta below the renal arteries (between L2 and L3).


The arteries pass inferolaterally under the parietal peritoneum over psoas major. The right testicular artery lies anterior to the inferior vena cava and posterior to the horizontal part of the duodenum. The left testicular artery lies posterior to the inferior mesenteric vein and the lower part of the descending colon. Each testicular artery crosses in front of the respective genitofemoral nerve and ureter to pass the deep inguinal ring and enter the spermatic cords. Along with the other contents of the cord, they enter the scrotum via the inguinal canal.


The terminal branches enter over the tunica albuginea to supply the testes and superior epididymis. Along their extended course, the testicular arteries also supply perirenal fat, the ureteric and iliac lymph nodes, and may supply the cremaster muscle in the inguinal canal.
