High Anti-Müllerian hormone (AMH): what it means

A Anti-Müllerian hormone (AMH) result above the normal range is considered high. Here is what a raised Anti-Müllerian hormone (AMH) can point to, and when it is worth discussing with a doctor.

Reference range: Roughly 1–4 ng/mL in fertile women; falls with age toward menopause, high in PCOS; no strong cut-off — read against age

What a high Anti-Müllerian hormone (AMH) can mean

  • Polycystic ovary syndrome (PCOS) — the commonest cause; many small follicles produce a lot of AMH.
  • High ovarian reserve — a larger remaining egg pool; can predict a strong (occasionally excessive) IVF response.
  • Granulosa cell tumour — rare; a persistently very high AMH without a PCOS explanation.

When to discuss with a doctor

AMH is most useful for planning, not for a yes/no verdict on fertility. A low result in a woman considering pregnancy is a reason to seek fertility advice sooner rather than to give up hope, and may support egg-freezing or earlier treatment. A high AMH with irregular periods and signs of excess androgens supports a PCOS assessment. Because AMH cannot tell you whether you will conceive this cycle, it should always be interpreted with age, FSH, estradiol and the overall picture. Mediora.AI shows AMH against age and its companion hormones; the fertility plan belongs with a gynaecologist or fertility specialist.
