The testicular vessels (ie, the artery, veins, and lymphatics) and nerves bore through the posterior border of the testis and ramify on the inner surface of the tunica albuginea and the septa. The deferent artery clings to the vas deferens, supplies it and the epididymis, and anastomoses freely with the testicular artery behind the testis. It also anastomoses with the cremasteric artery. Tying the testicular artery, therefore, does not necessarily result in the atrophy of the testis.
