AMH and spontaneous abortion: In the special population receiving ART-assisted reproductive treatment, when basic AMH ≤ 3.1 ng/mL, AMH was negatively correlated with the occurrence of miscarriage, and the odds ratio was 0.8 (95% CI = 0.7–0.8, P < 0.001), suggesting that the greater the value of AMH, the lower the incidence of spontaneous abortion.
