The round ligament of the uterus originates at the uterine horns, in the parametrium.

It leaves the pelvis via the deep inguinal ring [SUNYAnatomyLabs|43|03|02|01 - "The Female Pelvis: The Broad Ligament"] , passes through the inguinal canal and continues on to the labia majora [SUNYAnatomyLabs|36|03|01|05 - "Inguinal Region, Scrotum and Testes: The Internal Surface of the Anterior Abdominal Wall"] where its fibers spread and mix with the tissue of the mons pubis.


The function of the round ligament is maintenance of the anteversion of the uterus (a position where the fundus of the uterus leans ventrally). When the uterus grows during pregnancy, these ligaments can stretch causing pain. [cite web |url= |title=Pregnancy-Round Ligament Pain |accessdate=2008-01-27 |format= |work=]


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

Blood Supply

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