|Round ligament of the uterus|
Cross-section through the pelvis of a newly born female child. (Round ligament labelled at upper right.)
|Artery||uterine artery, artery of round ligament of uterus|
|Latin||ligamentum teres uteri|
The round ligament of the uterus originates at the uterine horns, in the parametrium. The round ligament exits the pelvis via the deep inguinal ring, passes through the inguinal canal and continues on to the labia majora where its fibers spread and mix with the tissue of the mons pubis.
The round ligament is supplied by the artery of the round ligament, otherwise known as "Sampson's artery."
The function of the round ligament is maintenance of the anteflexion of the uterus (a position where the fundus of the uterus is turned forward at the junction of cervix and vagina) during pregnancy.[dubious ] Normally, the cardinal ligament is what supports the uterine angle (angle of anteversion). When the uterus grows during pregnancy, the round ligaments can stretch causing pain.[unreliable medical source?]
