What AMH Tells You (and Doesn't)
AMH reflects the quantity of remaining eggs, not their quality. A woman with low AMH can still conceive naturally, and a woman with normal AMH doesn't guarantee fertility — age remains the strongest predictor of egg quality.AMH Reference Ranges by Age
| Age | Average AMH (ng/mL) |
|---|---|
| 25-29 | 3.0-4.0 |
| 30-34 | 2.0-3.5 |
| 35-39 | 1.0-2.5 |
| 40-44 | 0.5-1.5 |
| 45+ | <0.5 |
Clinical Uses
- Predicting response to IVF stimulation (higher AMH = more eggs retrieved, but not necessarily better quality)
- Assessing ovarian reserve before fertility treatment
- Diagnosing PCOS (often elevated AMH)
- Timing fertility preservation decisions (egg freezing)
AMH Doesn't Predict Natural Conception TimingAMH is a poor predictor of time to natural pregnancy in women under 40 without other fertility issues. It's most useful for IVF planning rather than for reassurance about natural fertility.
Can I improve my AMH level?
No treatment reliably increases AMH — it reflects a fixed ovarian reserve set at birth that naturally declines with age. Focus should be on family planning timing rather than trying to raise AMH.
Does low AMH mean I can't get pregnant?
No — many women with low AMH conceive naturally, especially if under 35. Low AMH mainly affects response to IVF stimulation (fewer eggs retrieved) rather than natural fertility directly.
Is AMH testing accurate on any day of the cycle?
Yes, unlike FSH, AMH levels are relatively stable throughout the menstrual cycle, making it convenient to test any day.
