👉 Foregirth is a measurement of how far the cervix extends from the opening to the uterus at its widest point. It is used in obstetrics and gynecology to assess the position of the cervix during pregnancy, as well as to predict fetal viability. The term "foregirth" refers to the distance between the opening of the cervix and the opening of the uterus, while "fetal viability" refers to whether or not a fetus is viable at that point in its development
