AMH & Ovarian Reserve Interpreter

AMH — anti-Müllerian hormone — is made by the small, resting follicles in your ovaries, so the level in your blood is a rough gauge of how many eggs you have left: your 'ovarian reserve.' The key word is quantity. As MedlinePlus puts it plainly, an AMH test 'can't tell you about the health of your eggs or predict whether you'll be able to get pregnant.' It's a measure of supply, not of egg quality and not of any single month's chance of conceiving. That distinction is the whole point of this tool: a number that tells you something real about egg count, and nothing at all about whether a healthy pregnancy will happen.

No. A low AMH means your remaining egg supply is on the smaller side; it does not mean you can't conceive, and plenty of people with a low AMH get pregnant naturally. The reason is that AMH measures quantity, not quality, and it isn't the main driver of month-to-month fertility — the ASRM's committee opinion is blunt that 'age is a much stronger predictor of reproductive success than is ovarian reserve,' and that ovarian-reserve markers 'do not predict current reproductive potential.' Where a low AMH genuinely helps is planning: it can hint at a shorter runway and it predicts how the ovaries respond to IVF stimulation. So a low value is a reason to talk with a clinician about timing — not a verdict, and not a diagnosis of infertility.

A higher AMH usually just reflects a larger pool of small follicles, and on its own it's not a problem — sometimes it's a good sign of a strong egg supply. It can, however, be associated with polycystic ovary syndrome (PCOS): MedlinePlus notes a high AMH 'is a sign that you may have' PCOS, while stressing that 'an AMH test alone cannot diagnose PCOS.' PCOS is diagnosed from the fuller picture — cycle patterns, symptoms like acne or excess hair growth, and ultrasound — not from one hormone. A high AMH also tends to predict a strong (sometimes over-brisk) response to IVF stimulation, which is useful information for a fertility team. If your value is high, bring it to a clinician to interpret alongside your cycles and symptoms.

Because age, far more than AMH, is what shapes the real chance of a pregnancy — and because AMH itself falls steadily with age. That means the same number carries a different meaning at 28 than at 42: a lower reading is expected in the early 40s and unremarkable, while the same reading in the late 20s is more worth a closer look. ACOG's guidance on age-related fertility decline and the ASRM opinion both put age at the centre, which is why this tool asks for it and adjusts the wording accordingly. What it can't do is convert age into a precise, personalised AMH cutoff — no standardized age-specific cutoffs exist — so it adjusts the interpretation, not the thresholds, and always points you back to your clinician and your own lab's range.

Because AMH assays aren't standardized. Different labs run different tests, and the same blood can return meaningfully different numbers depending on the assay used — the ASRM opinion notes that absolute values 'can differ from one another' and, tellingly, references low-reserve thresholds like 'under 1 ng/mL' and 'under 0.7 ng/mL' without endorsing any of them as the standard. So there is no universal pass/fail line. That's why the bands in this tool are labelled as general interpretive markers, not diagnostic cutoffs, and why the number that matters most is the one on your own lab report, read against that lab's reference range. If you're comparing results over time, try to use the same lab.

Yes. This tool runs entirely in your browser: the value and age you enter are converted and interpreted on your own device and are never sent to a server, saved, or shared — close the tab and they're gone. We treat reproductive-health data as sensitive by default, so there's no account and nothing to delete. What you see is general educational information based on published guidance from ASRM, ACOG, and MedlinePlus; it isn't medical advice, a diagnosis, or a fertility verdict, and it can't replace the clinician who ordered your test.
