Method： If the HCG levels during the late pregnancy were related to the delivery mechanism was studied by using the β -HCG changes of 100 women pregnant for 36 weeks, 37 weeks, 38 weeks, 39 weeks, 40 weeks, and 41 weeks, and also the [3 -HCG changes when their uterine orifice was opened for 3cm near the time of labor as the clinical data. All these cases were found to suffer no clinical complications. Result： The difference in HCG changes during the late pregnancy was of no statistical significance （P〉0.05）. Conclusion： The β-HCG levels change during the late pregnancy is not significantly correlated with the labor onset time, and the labor onset time is unpredictable with the monitoring of the HCG levels change during the late pregnancy.展开更多
