Patient Education Hub • Fertility Tests & Ovarian Reserve

Anti‑Müllerian Hormone (AMH)

AMH is a hormone made by small ovarian follicles. A simple blood test helps estimate ovarian reserve (how many eggs may remain) — one part of the overall picture.

Ovarian reserve Any day test Context matters

Key takeaways

  • AMH estimates egg quantity, not overall fertility or natural conception chances.
  • Levels vary with age and conditions (e.g., higher in PCOS, lower after ovarian surgery/chemo).
  • Results should be interpreted with age, ultrasound (AFC), and history by your specialist.

When do doctors order AMH?

  • Before fertility treatment or egg freezing planning
  • To help individualise IVF stimulation dosing
  • When low ovarian reserve is suspected
  • As part of evaluating possible PCOS (often elevated)

How the test works

Before: No fasting is required. AMH can be drawn on any day of your cycle.
During: A quick blood sample is taken. The tube is sent to our lab.
After: Results usually return within 1–2 working days. Use the same lab when monitoring trends.

Interpreting results

  • Ranges differ by laboratory; one number cannot diagnose infertility.
  • Trends over time and ultrasound findings often matter more than a single result.
  • High AMH in PCOS does not mean better egg quality; it reflects more small follicles.

What AMH does not show

  • Egg quality or embryo genetics
  • Whether your tubes are open or if you ovulate regularly
  • Your exact chance of pregnancy in a given month
  • Time to menopause

Common myths

  • “Low AMH means no chance.” → Many people conceive with low AMH; it mainly predicts response to stimulation.
  • “High AMH guarantees IVF success.” → Not necessarily; quality relates strongly to age.
  • “Supplements can raise AMH reliably.” → Evidence is mixed; discuss any supplements with your doctor.

Frequently asked questions

Do I need to fast?
No. AMH does not require fasting.

Which day of the cycle is best?
Any day is acceptable; AMH is relatively stable across the cycle.

Does birth control affect AMH?
Combined pills or long‑term contraception may slightly lower measured AMH. Tell your clinician so we can interpret results correctly.

How often should I repeat AMH?
Only if results will change management — commonly 6–12 months later or as advised.

Can PCOS raise AMH?
Yes; AMH is often higher in PCOS due to more small follicles. It doesn’t guarantee egg quality.

Next steps: Your AAFC specialist will review AMH alongside ultrasound and other tests to build a personalised plan.
