How is cephalopelvic disproportion (CPD) diagnosed? The diagnosis of cephalopelvic disproportion is often used when labor progress is not sufficient and medical therapy such as use of oxytocin is not successful or not attempted. CPD can rarely be diagnosed before labor begins if the fetus is thought to be large or the mother’s pelvis is known to be small.
