In obstetrics a<unk>  is the conduction of spontaneous<unk>  in a moderate degree of cephalopelvic disproportion. It is performed under close observation by an obstetrician in order to assess a woman's chances of a successful vaginal birth. The physician may allow<unk>  to continue against contraindications during birth or even stimulate<unk>  with oxytocin when pelvic measurements are borderline to see if the fetal head will descend making vaginal delivery possible; if progressive changes in dilation and station do not occur, a cesarean delivery is performed.
