Attachments The inguinal ligament arises from the anterior superior iliac spine and attaches to the pubic tubercle although there are some fibers which attach elsewhere as extensions or reflections of the inguinal ligament: some fibers pass posteriorly to attach to the superior pubic ramus forming the lacunar ligament of Gimbernat fibers that run with the lacunar ligament continue to pass more laterally to attach to the pecten pubis forming pectineal ligament of Cooper superior fibers run past the pubic tubercle to fuse with those of the contralateral external oblique aponeurosis forming the reflected inguinal ligament The upper surface of the ligament gives origin to the external spermatic fascia from its medial part, internal oblique muscle from the lateral two-thirds and transversus abdominis muscle from its lateral one-third.

Its collagen fibers arise from the inferior aponeurosis of the external abdominal oblique and run obliquely across the pelvis. The inguinal ligament supports the muscles that run inferior to its fibers, including the iliopsoas and pectineus muscles of the hip. It also supports the nerves and blood vessels of the leg as they pass through the groin, including the femoral artery, femoral vein, and femoral nerve.
The support provided by the inguinal ligament is important to maintaining the flexibility of the hip region while allowing vital blood and nerve supply to the leg. A small opening in the muscles and connective tissues of the abdomen — known as the superficial inguinal ring — is located just superior to the inguinal ligament.
This opening forms part of the inguinal canal, which permits the spermatic cord in males and the round ligament of the uterus in females to exit the abdominopelvic cavity and pass through the external tissues of the pelvis.
