Monitoring the baby's heartbeat assesses the baby's health and can help the doctor decide whether to let the pregnancy go on or to induce labor. Two methods can be used to conduct the contraction stress test. In the first, the woman's nipples are stimulated, causing her brain to secrete oxytocin, a hormone that induces uterine contractions. The second method is the oxytocin challenge test\u00a0(OCT), in which a small amount of synthetic oxytocin (Pitocin) is introduced intravenously to stimulate contractions.A procedure used to evaluate placental sufficiency by assessing fetal response to the physiological stress of artificially induced uterine contractions. Contractions may be generated by breast stimulation or by the oxytocin challenge test."}
