AMH and Infertility: The frequency of tubal-factor infertility in the low-AMH group was significantly higher than that in the high-AMH group (66.08% vs. 60.21%, p < 0.01), but there was no difference with the average-AMH group (66.08% vs. 64.74%, p = 0.7) (Table 1, Additional file 1: Table S1 and Table S2).
