What Is the Normal AMH Level by Age?

Normal AMH levels vary with age as ovarian reserve naturally declines. For women in their 20s to early 30s, AMH levels typically range from 2.0 to 6.8 ng/mL, indicating a healthy ovarian reserve. By the mid-30s, levels may decrease to 1.5–4.0 ng/mL, and by the early 40s, levels often fall below 1.0 ng/mL, reflecting diminished ovarian reserve. These ranges are guidelines and can vary based on lab methods and individual differences. Understanding AMH levels in the context of age provides a valuable fertility assessment. Women with unusually high or low AMH levels for their age should consult a fertility specialist to explore potential underlying conditions, treatment options, or considerations for fertility preservation.
