AMH and spontaneous abortion: The higher AMH (AMH > 1.1) group had less total Gn (bottle) (35 (25–44) vs. 42 (36–50.8), P = 0.00 < 0.05) and a lower starting Gn (IU) ((225 (150–300) vs. 300 (225–300), P = 0.00 < 0.05), while the numbers of oocytes obtained,the numbers of MII,the numbers of cleavages and the numbers of high-quality embryos were greater (P = 0.00 < 0.05).The participants' pregnancy outcome (ectopic pregnancy, miscarriage, singleton, twin, multiple births) could not be predicted by AMH as shown through ROC curves (P > 0.05).
