AMH and Ovarian Reserve: What Your Result Means
Understanding anti-Müllerian hormone and fertility potential.
Anti-Müllerian hormone (AMH) is produced by the small follicles in the ovaries. Because it reflects the remaining pool of eggs, AMH has become one of the most important blood tests for assessing ovarian reserve.
What Is Ovarian Reserve?
Ovarian reserve refers to the number and quality of eggs remaining in the ovaries. It naturally declines with age. A higher reserve generally means better fertility potential and a stronger response to fertility medications.
Typical AMH Levels by Age
| Age | Typical AMH Range (ng/mL) |
|---|---|
| 20–24 | 2.0–6.8 |
| 25–29 | 1.5–5.5 |
| 30–34 | 1.0–4.0 |
| 35–39 | 0.5–2.5 |
| 40–44 | 0.1–1.0 |
Interpreting Low AMH
A low AMH suggests a diminished egg supply. This does not mean pregnancy is impossible, but it may indicate:
- Reduced fertility window
- Poorer response to ovarian stimulation during IVF
- Higher risk of early menopause
Interpreting High AMH
Very high AMH can be a sign of polycystic ovary syndrome (PCOS), which is associated with many small follicles. While this suggests a large egg supply, it can also mean irregular ovulation and difficulty conceiving naturally.
Limitations
AMH does not predict egg quality or the chance of natural conception in the next month. It is best used alongside other tests (antral follicle count, FSH) and clinical evaluation.
