Which structure is not contained within, or attached to, the broad ligament?

The suspensory ligament of the ovary passes from the fascia over psoas major to attach to the ovary. The round ligament is attached to the lateral angle of the uterus and runs in the anterior layer of the broad ligament. It passes through the inguinal ring to be attached the labia majora. The uterine vessels enter the lateral wall of the uterus by running in the inferior free border of the broad ligament. The fallopian tube runs in the superior border of the broad ligament.
