The round ligament of the uterus originates at the uterine horns, in the parametrium. The round ligament leaves the pelvis via the deep inguinal ring,[2] passes through the inguinal canal and continues on to the labia majora[3] where its fibers spread and mix with the tissue of the mons pubis.

Function[edit]

The function of the round ligament is maintenance of the anteversion of the uterus (a position where the fundus of the uterus leans ventrally) during pregnancy. 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.[4]

Embryology[edit]

The round ligament develops from the gubernaculum which attaches the gonad to the labioscrotal swellings in the embryo.[1]

Blood Supply[edit]

The round ligament is supplied by the artery of the round ligament, otherwise known as "Sampson's artery."
