Inguinal canal

Watch video

The inguinal canal is an oblique tubular passage that connects the pelvis and perineum. It originates superolaterally at the deep inguinal ring, traverses the abdominal wall and terminates at the superficial inguinal ring near the pubic tubercle.

During fetal life, the inguinal canal in males allows for the physiological descension of the testes into the scrotum. In adult life, the inguinal canal serves as a conduit for the spermatic cord and ilioinguinal nerve in males. In females, the inguinal canal is less prominent due to the absence of the spermatic cord, however, it does provide the passage for the round ligament of uterus and ilioinguinal nerve.

The inguinal canal is the weakest point of the trunk wall and as such, an often site for herniations (inguinal hernia), especially so in males due to the descent of the testis.
