To determine whether AMH has a predictive value for pregnancy outcomes, by following up the pregnancy outcomes of IVF,participants, including ectopic pregnancy, miscarriage, singleton, twins and multiple births, using ROC curves, we found that AMH may not have a good predictive value for pregnancy (Fig. 3) outcomes of IVF (P = 0.980, 0.093, 0.447, 0.146, 0.526, > 0.05) (see Table 2). The gene discussed is AMH; the disease is spontaneous abortion.
