Enter your Anti-Müllerian Hormone (AMH) test result and age to see where it sits against commonly cited age-based reference ranges. A reference lookup only — not a fertility prediction or diagnosis.
AMH (Anti-Müllerian Hormone) is a blood test that reflects the approximate size of your remaining egg supply — your ovarian reserve — and it naturally declines with age. It does not measure egg quality, and it is not a pregnancy test or a fertility test on its own. Many people with low AMH conceive naturally, and AMH does not reliably predict how long it will take to get pregnant. It is used mainly to help fertility specialists plan IVF stimulation protocols. This calculator compares your result with commonly cited reference data for your age band — always check your own lab's printed reference range too, since assays vary between labs.
⚕️ Medical Notice: This calculator provides a general reference comparison only, using commonly cited age-based AMH data. It does not diagnose infertility, diminished ovarian reserve, or PCOS, and it does not predict your chance of natural or assisted conception. Labs use different assay methods, so absolute AMH numbers can vary between labs — always compare your result with the reference range printed on your own lab report, and interpret any result together with your doctor or fertility specialist.
| Parameter | Value |
|---|
This tool takes your AMH result and age, converts the value to ng/mL if needed, and compares it against both a general population reference band and a typical range for people around your age. It does not calculate a formula-based score — it is a reference lookup against commonly cited data.
| General AMH Band | Approx. Range | What It Generally Suggests |
|---|---|---|
| Low | Below 1.0 ng/mL | Reduced ovarian reserve relative to the general reference population |
| Typical / Average | 1.0–4.0 ng/mL | Within the commonly cited average range |
| High | Above 4.0 ng/mL | Above typical — worth discussing with a doctor, including possible PCOS |
Average AMH levels tend to decline gradually with age as ovarian reserve naturally decreases over time. The figures below are commonly cited reference bands, not fixed cut-offs — they vary between labs and assay methods, so always check the reference range printed on your own results.
| Age Band | Commonly Cited Typical Range (ng/mL) |
|---|---|
| Under 25 | Approx. 3.0–8.0 |
| 25–29 | Approx. 2.5–6.0 |
| 30–34 | Approx. 1.5–5.0 |
| 35–37 | Approx. 1.0–4.0 |
| 38–40 | Approx. 0.5–3.0 (average around 1.0 near age 40) |
| 41–42 | Approx. 0.3–2.0 |
| 43–44 | Approx. 0.1–1.0 |
| 45 and over | Often around 0.5 or lower |
AMH (Anti-Müllerian Hormone) is produced by small follicles in the ovaries, and the amount circulating in your blood gives a rough indication of how many follicles — and therefore how many eggs — remain in your ovarian reserve at that point in time. That is genuinely useful information in certain clinical contexts, particularly for fertility specialists planning an IVF cycle, because it helps estimate how a person's ovaries might respond to stimulation medication and helps guide the dose used.
What AMH does not tell you is just as important. It does not measure egg quality — the genetic and cellular health of the eggs that remain — which is a separate factor that declines with age largely independently of the quantity reflected by AMH. It is not a pregnancy test, and it is not validated as a general fertility test for people not undergoing IVF. Many people with low AMH results go on to conceive naturally without any assistance, and a high AMH result does not guarantee an easy conception either — in fact, significantly elevated AMH is also associated with polycystic ovary syndrome (PCOS), so a high number should not automatically be read as good news. Research has also found that AMH is, at best, only weakly correlated with the age a person will reach menopause, so it should not be used to predict that either.
| AMH (ng/mL) | General Category | General Notes |
|---|---|---|
| Below 1.0 | Low | Suggests a reduced ovarian reserve relative to the general population; some clinicians specifically use a threshold below 1.2 ng/mL for "diminished ovarian reserve" |
| 1.0–3.5 | Typical / Average | Within the commonly cited average range for the general reproductive-age population |
| 3.5–4.0 | Upper end of typical | Near the top of the average range, approaching the higher band |
| Above 4.0 | High | Above typical; can reflect a strong ovarian reserve but is also associated with PCOS |
These bands are commonly cited in reproductive endocrinology reference material, but different labs and different assay platforms can report meaningfully different absolute numbers for the same blood sample. That is why doctors always recommend comparing your result to the specific reference range printed on your own pathology report rather than relying solely on generic bands like the ones above.
What is AMH?
AMH (Anti-Müllerian Hormone) is a hormone produced by small follicles in the ovaries. The level in your blood gives an approximate indication of your remaining ovarian reserve — roughly how many eggs are left — at the time of testing. It is measured with a simple blood test that can be taken at any point in your menstrual cycle.
What does a low AMH result mean?
A low AMH result means fewer eggs are estimated to remain in your ovarian reserve compared with the typical range for your age. It does not mean you are infertile. Natural conception is still very possible with a low AMH, since AMH reflects egg quantity, not egg quality, and does not reliably predict how long it will take to conceive.
What does a high AMH result mean?
A high AMH result means more follicles than typical were detected, which can simply reflect a strong ovarian reserve, but it can also indicate polycystic ovary syndrome (PCOS), which often involves a higher-than-average number of small follicles. A high result should not be interpreted as "definitely more fertile" — it is worth discussing with a doctor, particularly if you also have irregular periods or other PCOS symptoms.
Does AMH predict when I'll go through menopause?
Not reliably. While very low AMH can sometimes suggest menopause may occur earlier, research has generally found only a weak correlation between AMH levels and actual age at menopause. It should not be relied on to predict your personal menopause timing.
How is AMH used in IVF?
In IVF, AMH is one of the main tests used to help plan a stimulation protocol. It gives fertility specialists a rough guide to how many eggs a stimulation cycle might retrieve, which helps them choose an appropriate starting dose of stimulation medication and anticipate whether a person may be a lower or higher responder.
Can AMH levels change over time?
Yes, AMH can show some fluctuation between tests due to lab variation and other factors, but the overall trend is a gradual decline with age, which is the main driver of change over the years. A single test is a snapshot, and short-term fluctuation is generally less important than the broader age-related trend.
How accurate is a single AMH test?
A single AMH test gives a useful snapshot, but it is not a complete picture on its own. Results can vary between laboratories due to different assay methods, and a single number does not capture egg quality, other fertility factors, or your full reproductive health. That's why doctors interpret AMH alongside other tests and your medical history rather than in isolation.
Should I be worried about a low AMH result?
A low result on its own is not a reason to panic — talk it through with your doctor, who can put it in context. Many factors matter more than a single AMH number for your overall chances of conceiving, including your age, ovulation regularity, and other aspects of reproductive health. If you have concerns, a healthcare professional or fertility specialist can help you understand what your result does and doesn't mean for you.
Why does my AMH result look different from my lab's reference range?
Different laboratories use different assay platforms to measure AMH, and these can produce meaningfully different absolute numbers for the same sample. This calculator uses commonly cited general reference bands for educational comparison, but you should always check the specific reference range printed on your own lab report, since that is calibrated to the assay your sample was actually run on.
Is AMH the same as a fertility test?
No. AMH is one piece of information about ovarian reserve, but it is not a comprehensive fertility test. A full fertility assessment also considers ovulation, fallopian tube patency, uterine health, and — for couples — semen analysis, among other factors. AMH alone cannot tell you whether or how easily you will conceive.
