Round ligament of the uterus (female)

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, 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.  When the uterus grows during pregnancy, the round ligaments can stretch causing pain.  The round ligament of the uterus is a remnant of the fetal gubernaculum.
