If a woman has weak contractions during labor that slow down the labor process, stimulation of the nipples can be used to promote uterine contractions in order to prevent fetal asphyxia, which will help strengthen contractions and allow the fetus to be expelled from the vagina as soon as possible. Nipple stimulation is done by the doctor or family member touching the woman’s breast with their fingers to make the nipples contract and become harder and more sensitive, which reflexively leads to stronger uterine contractions to speed up labor. When using nipple stimulation to induce labor, the breast should not be stimulated with excessive force, but should be massaged in one direction and not with excessive force.
