Testicular artery at a glance

What it is
A paired branch of the abdominal aorta to the testis.
Location
It arises below the renal arteries, passes through the inguinal canal in the spermatic cord and reaches the testis.

Key facts

  • It arises from the aorta at about L2, a reminder that the testis develops high in the abdomen before descending.

Clinical relevance

Torsion of the spermatic cord can cut off its blood flow and threaten the testis.
