Is your AMH normal for your age? Interpret your result

Enter your AMH level (ng/mL) and age. The calculator compares your result against age-adjusted reference ranges (Seifer et al. 2011 / ASRM) and tells you if your ovarian reserve is low, normal, or high — with a reference table, worked example, and next-step guidance.

Anti-Müllerian hormone (AMH) is produced by small follicles in the ovaries and is the most reliable blood marker of ovarian reserve — the pool of eggs remaining. Because AMH declines with age, a result that looks low at 28 may be completely normal at 42. This calculator compares your AMH level against age-adjusted reference ranges used in clinical fertility practice (based on data from large population studies published in Fertility and Sterility and endorsed by ASRM) and tells you where your result falls: low, normal, or high. It does not replace a consultation with a reproductive endocrinologist.

When to use this calculator

A 34-year-old planning to start a family in 1–2 years wants to understand whether her AMH of 1.8 ng/mL is a concern for her age.
A 38-year-old beginning IVF consultation uses this to understand how her AMH of 0.7 ng/mL fits the expected range before her first appointment.
A 28-year-old with irregular cycles and suspected PCOS checks whether her AMH of 7.2 ng/mL is consistent with polycystic ovary syndrome.
A couple seeking egg freezing counseling wants a plain-language interpretation of a lab report showing AMH 3.4 ng/mL at age 31.

AMH reference ranges by age group (ng/mL)

Age group	Normal range	Low (diminished reserve)	High (possible PCOS)
Under 30	2.0–5.0 ng/mL	< 2.0 ng/mL	> 5.0 ng/mL
30–34	1.5–4.0 ng/mL	< 1.5 ng/mL	> 4.0 ng/mL
35–39	0.9–3.0 ng/mL	< 0.9 ng/mL	> 3.0 ng/mL
40 and over	0.5–2.0 ng/mL	< 0.5 ng/mL	> 2.0 ng/mL

How it works

Normal AMH levels by age — reference table

AMH declines predictably with age because ovarian follicle pools shrink over time. The table below shows reference values by age bracket, based on Seifer et al. (2011) (Fertility and Sterility, 17,120 US fertility-center patients) and consistent with ASRM 2020 committee opinion:

Age group	Normal range	Low (diminished reserve)	High (possible PCOS)
Under 30	2.0–5.0 ng/mL	< 2.0 ng/mL	> 5.0 ng/mL
30–34	1.5–4.0 ng/mL	< 1.5 ng/mL	> 4.0 ng/mL
35–39	0.9–3.0 ng/mL	< 0.9 ng/mL	> 3.0 ng/mL
40 and over	0.5–2.0 ng/mL	< 0.5 ng/mL	> 2.0 ng/mL

> Unit conversion: if your result is in pmol/L, divide by 7.14 to get ng/mL. Example: 14 pmol/L ÷ 7.14 = 1.96 ng/mL.

What is AMH?

Anti-Müllerian hormone is secreted by granulosa cells of pre-antral and small antral follicles. Unlike FSH, AMH does not fluctuate significantly across the menstrual cycle, so it can be measured at any point and gives a stable snapshot of ovarian reserve. It is the preferred biomarker recommended by the American Society for Reproductive Medicine (ASRM) for ovarian reserve testing.

How the classification works

The calculator places your AMH value into one of three zones based on the age-adjusted thresholds:

Low (diminished ovarian reserve): AMH below the lower threshold for your age suggests fewer remaining follicles than typical. This does not prevent pregnancy but may shorten the natural conception window and reduce IVF egg retrieval counts.

Normal for age: AMH within the expected range indicates an ovarian reserve consistent with your age group.

High (possible PCOS): AMH above the upper threshold is common in polycystic ovary syndrome, where many small follicles accumulate. High AMH can be associated with irregular ovulation and increased risk of ovarian hyperstimulation syndrome (OHSS) during IVF stimulation.

Important limitations

AMH measures quantity of follicles, not egg quality. Women with low AMH conceive regularly.

Results vary between laboratories and assay brands (Elecsys vs. Beckman Coulter Gen II). Always compare against your lab's own reference intervals.

Oral contraceptives, GnRH agonists, and some hormonal therapies can temporarily suppress AMH by 10–30%.

AMH cannot predict the timing of menopause with precision at the individual level.

This calculator is for educational orientation only. A reproductive endocrinologist or gynecologist must interpret your result in the context of your full medical history.

Worked example: AMH 1.1 ng/mL at age 37

AMH entered: 1.1 ng/mL. Age: 37 years.

Age bracket 35–39 → expected normal range: 0.9–3.0 ng/mL.

1.1 ng/mL falls inside the range.

Classification: Normal for age — though in the lower quarter of the bracket.

Normal for age — adequate fertility expected. Recommendation: keep regular checkups. Because the result is in the lower quarter of the 35–39 bracket, discussing timing with a gynecologist is sensible.

Frequently asked questions

What is a normal AMH level for my age?

Normal ranges shift with each decade of life. Under 30: 2.0–5.0 ng/mL is typical. Ages 30–34: 1.5–4.0 ng/mL. Ages 35–39: 0.9–3.0 ng/mL. Age 40 and over: 0.5–2.0 ng/mL. These are population medians — there is always individual variation, and your lab's own reference intervals may differ slightly.

Can I get pregnant with a low AMH?

Yes. AMH reflects egg quantity, not quality. Many women with AMH below 1 ng/mL — even below 0.5 ng/mL — conceive naturally or with IVF. The ASRM explicitly states that extremely low AMH alone should not be used to deny IVF treatment. Diminished reserve means your window may be shorter, not closed.

Does AMH tell me anything about egg quality?

No. AMH only measures how many follicles are maturing in your ovaries right now. Egg quality depends largely on age and is influenced by chromosomal integrity, which no blood test can directly measure. This is why age is still the single strongest predictor of IVF success, not AMH alone.

My AMH came back high — is that good?

A high AMH (above 4–5 ng/mL depending on age) often reflects a large pool of follicles. This can be good for IVF egg retrieval, but very high AMH is associated with polycystic ovary syndrome (PCOS), which can cause irregular ovulation and cycle problems. It also increases the risk of ovarian hyperstimulation syndrome during fertility treatment. A gynecologist should evaluate any AMH above the upper reference range.

Why does my AMH result differ between labs?

AMH immunoassays are not standardized across manufacturers. The Elecsys AMH Plus assay (Roche), the Beckman Coulter Gen II assay, and others use different calibrators and give systematically different readings from the same blood sample. Always compare your result against the reference range provided by your specific laboratory, not generic internet tables.

Can birth control pills lower my AMH?

Yes, temporarily. Combined oral contraceptives can suppress AMH by roughly 10–30% while you are taking them. If you are on the pill or recently stopped, mention this to your doctor when interpreting AMH results. The suppression reverses after discontinuing contraception, typically within one to three months.

Is there a way to increase AMH levels?

No proven clinical treatment increases AMH. Some studies have explored DHEA, melatonin, and CoQ10 supplementation, but evidence is insufficient and ASRM does not recommend these to improve ovarian reserve. Smoking cessation, maintaining a healthy body weight, and avoiding unnecessary ovarian surgery (which can reduce functional tissue) help preserve existing reserve.

When should I have my AMH tested?

AMH is worth testing if you: are planning to delay pregnancy past 35; are considering egg freezing; have been trying to conceive without success for 6–12 months; have a family history of early menopause; have had ovarian surgery, chemotherapy, or radiation; or have irregular cycles suggestive of PCOS. AMH can be drawn on any day of the menstrual cycle.

How does AMH relate to IVF outcomes?

AMH is primarily used in IVF to predict ovarian response to gonadotropin stimulation: how many eggs are likely to be retrieved. Low AMH predicts a poor response (fewer eggs); high AMH predicts a strong response but higher OHSS risk. It is not a reliable predictor of live birth rates by itself — age, embryo chromosomal status, and uterine factors also determine outcome.

Does AMH predict when I will enter menopause?

AMH declines gradually and becomes undetectable around the time of menopause. While some models use AMH to estimate when menopause may occur, prediction at the individual level remains imprecise. ACOG (2025) notes that anticipatory counseling about ovarian-factor fertility decline is important, but single AMH measurements cannot pinpoint a menopause date.
