Understanding AMH and Ovarian Reserve

A clear explanation of what AMH measures, how to interpret your result, and what it means for your fertility options.

What is AMH?

Anti-Müllerian Hormone (AMH) is produced by small follicles in the ovaries. It remains relatively stable throughout your menstrual cycle and is the best single blood test for measuring ovarian reserve — the number of eggs remaining in your ovaries.

AMH Reference Ranges

>3.5 ng/mL: High reserve (may suggest PCOS)
1.5–3.5 ng/mL: Normal/Good reserve
1.0–1.5 ng/mL: Satisfactory reserve
0.5–1.0 ng/mL: Low-normal — monitor closely
<0.5 ng/mL: Low reserve — expedited treatment recommended
<0.1 ng/mL: Very low — may indicate POI/early menopause

What AMH Does NOT Tell You

It does NOT measure egg quality — only quantity
A low AMH does not mean you cannot get pregnant — it means there is less time
AMH does not predict menopause onset precisely

What to Do with a Low AMH

Fertility assessment urgently — don't wait
Consider egg/embryo freezing now if not ready for pregnancy
IVF is possible even with AMH 0.1–0.5 ng/mL
Supplements (DHEA 75 mg/day, CoQ10 400 mg/day) may help — discuss with your doctor
Donor eggs offer >50% success rate regardless of your AMH
