🌿 Key Takeaway
AMH (anti-Müllerian hormone) is the single best blood test for estimating ovarian reserve — the quantity of eggs remaining. It's stable throughout your cycle, inexpensive, and gives actionable data. But AMH tells you about quantity, not quality. A low AMH does not mean you can't get pregnant — it means you may have fewer years of fertility left and should consider acting sooner rather than later. A normal AMH does not guarantee easy conception. It's one data point, not a verdict.
What AMH Measures
AMH is produced by the granulosa cells of small growing follicles in the ovaries. The more small follicles you have, the higher your AMH. It correlates with the total pool of remaining eggs (ovarian reserve) and predicts how your ovaries will respond to stimulation medications (relevant for IVF and egg freezing).
| AMH Level (ng/mL) | Interpretation | What It Means for You |
|---|---|---|
| Above 3.5 | High reserve | Abundant eggs; excellent response to stimulation; slightly higher OHSS risk in IVF |
| 1.5–3.5 | Normal reserve | Age-appropriate for most women under 35; good fertility prospects |
| 1.0–1.5 | Low-normal | May indicate early decline; consider acting on family planning sooner |
| 0.5–1.0 | Low / Diminished Ovarian Reserve | Reduced quantity; discuss timeline and options with RE; egg freezing may be urgent |
| Below 0.5 | Very low | Significantly depleted reserve; may need aggressive treatment; time is critical |
What AMH Does NOT Tell You
- Egg quality: AMH measures quantity, not quality. A woman with low AMH but good egg quality (young age) may conceive easily. A woman with high AMH but poor quality (older age, genetic factors) may not.
- Whether you can get pregnant naturally: Women with low AMH conceive naturally every day. It takes only one good egg per cycle.
- Exactly when menopause will occur: AMH trends predict the trajectory, but the exact timeline is still imprecise.
- Your fertility right now: AMH is a marker of reserve, not current-cycle fertility. A woman with AMH 0.8 who is ovulating regularly this month has the same per-cycle chance as a woman with AMH 3.0 (assuming similar age and egg quality).
⚠ The panic trap
Many women get a low AMH result and spiral into crisis. Context matters enormously. An AMH of 1.0 at age 28 is more concerning than an AMH of 1.0 at age 38 (because it suggests accelerated depletion). Low AMH does not mean infertility — it means reduced time. The appropriate response is not panic; it's informed action: consult an RE, discuss timeline, consider egg freezing if pregnancy isn't imminent, and optimize the factors you can control.
When to Test
- Proactively at 30–32: Even if you're not planning pregnancy yet. Baseline data lets you make informed decisions.
- If you have risk factors: Family history of early menopause, endometriosis, ovarian surgery, autoimmune conditions, BRCA mutation carriers.
- Before egg freezing: AMH predicts how many eggs you're likely to retrieve per cycle.
- After 6+ months of trying (if over 35): Part of the standard fertility workup.
✅ How to get tested
AMH can be drawn any day of your cycle (unlike FSH, which must be tested on day 2–3). A simple blood draw at your OB/GYN, RE, or even via at-home test kits (Modern Fertility, LetsGetChecked). Results in 1–3 days. Cost: $30–80 out of pocket if not covered by insurance. This is one of the highest-value medical tests you can get for fertility planning.
Act on Your Results
If your AMH suggests you should move sooner, egg freezing preserves your options.
