In the aponeurosis of the external oblique, immediately above the crest of the pubis, is a triangular opening, the subcutaneous inguinal ring (superficial inguinal ring, external inguinal ring), formed by a separation of the fibers of the aponeurosis in this situation.

The subcutaneous inguinal ring is situated 1 centimeter above and lateral to the pubic tubercle. It has medial and lateral crura. It is at the layer of the aponeurosis of the Obliquus externus abdominis.^[1]

The superficial inguinal ring forms the exit of the inguinal canal, through which the illioinguinal nerve, the genital branch of the genitofemoralnerve, and the spermatic cord (in men) or the round ligament (in women) pass. The deep inguinal ring is the entrance to the inguinal canal.^[2]

The superficial ring is dilated in a condition called athletic pubalgia.
