AMH and Infertility: For example, a recent time-to-pregnancy cohort study14 of women aged 30 to 44 years without a history of infertility found that there was no significant association between diminished ovarian reserve (AMH level <0.7 ng/ml) and risk of future infertility (relative risk [RR], 0.65; 95% CI, 0.21-2.07) or future fecundability (fecundability ratio, 0.97; 95% CI, 0.59-1.60).
