AMH (Anti-Müllerian Hormone): What Your Result Means

What is AMH (Anti-Müllerian Hormone)?

Anti-Müllerian hormone is made by granulosa cells of small antral follicles. Because those follicles are present in a fairly stable number at any time, AMH gives a snapshot of ovarian reserve. Levels decline with age and are not tied to the day of the cycle, so it can be drawn any time.

Typical reference interval: Interpreted by age; laboratories report age-specific ranges. Levels generally decline through the 30s and fall to very low after menopause.. Laboratories differ — the interval printed on YOUR report always governs.

If your AMH (Anti-Müllerian Hormone) is high

Common reasons AMH (Anti-Müllerian Hormone) runs above the reference interval:

• PCOS — polycystic ovary syndrome often raises AMH because of many small follicles
• Larger ovarian reserve — higher values generally suggest a larger remaining follicle pool
• Rare granulosa-cell tumors — can produce very high AMH

If your AMH (Anti-Müllerian Hormone) is low

Common reasons AMH (Anti-Müllerian Hormone) runs below the reference interval:

• Advancing age — the main reason AMH declines
• Diminished ovarian reserve — fewer remaining follicles — relevant for fertility planning
• Post-menopause — very low or undetectable
• Ovarian surgery, chemotherapy, or smoking — can accelerate the decline

Symptoms worth knowing

AMH causes no symptoms; it is used to inform fertility counselling and IVF planning rather than to explain a feeling.

What usually happens next

1. Interpret with age, FSH, antral follicle count, and your fertility goals
2. A low AMH means fewer eggs remain but does not mean pregnancy is impossible
3. A high AMH with irregular cycles may prompt evaluation for PCOS
