Correct Answer � B
Explanation

|
Answer B) Abdominal aorta
Explanation: The spermatic cord contains three arteries: testicular artery, artery of the ductus deferens, and cremasteric artery.
-
The abdominal aorta branches around L2 into the paired testicular arteries, which serve as the primary blood supply to the testes.
-
The testicular artery’s course within the spermatic cord makes it susceptible to injury during inguinal hernia repair.
-
Collateral blood supply is provided by branches of the cremasteric artery and artery of the ductus deferens, which anastomose with the main testicular artery distally.
