AMH Levels by Age Chart 2026: Normal Range at 25, 30, 35, 40 (ng/mL & pmol/L)

What Is AMH? (Anti-Müllerian Hormone Explained)

AMH stands for Anti-Müllerian Hormone. It is produced by the small developing follicles in your ovaries, so the more follicles you have remaining, the higher your AMH level. Because of this, AMH is the single best blood test for estimating ovarian reserve — the size of your remaining egg supply. Importantly, AMH measures egg quantity, not egg quality, and it cannot predict whether or when you will conceive on its own. Age remains the strongest predictor of egg quality.

• Produced by: small (pre-antral and early antral) follicles in the ovaries
• What it measures: ovarian reserve (egg quantity)
• What it does NOT measure: egg quality, whether you can conceive, or when menopause will arrive
• Stable across the cycle: can be tested any day, no fasting required
• Common units: ng/mL (North America), pmol/L (Europe and Australia)

Normal AMH Levels by Age: Complete Reference Chart

The following chart shows average AMH levels in ng/mL for each age group, based on data from major fertility studies and laboratory reference ranges. Individual variation is wide — these are population averages, not strict cutoffs.

• Under 25 years: Average 3.0–4.5 ng/mL | Normal range: 1.5–6.0 ng/mL
• 25–29 years: Average 2.5–3.5 ng/mL | Normal range: 1.2–5.0 ng/mL
• 30–34 years: Average 1.5–3.0 ng/mL | Normal range: 0.8–4.0 ng/mL
• 35–37 years: Average 1.0–2.5 ng/mL | Normal range: 0.5–3.5 ng/mL
• 38–40 years: Average 0.7–1.5 ng/mL | Normal range: 0.3–2.5 ng/mL
• 41–43 years: Average 0.3–1.0 ng/mL | Normal range: 0.1–1.5 ng/mL
• Over 43 years: Average 0.1–0.5 ng/mL | Normal range: <1.0 ng/mL

How to Read Your AMH Result Against the Chart

When comparing your AMH result to the age chart, focus on where you fall within the range for your age group rather than fixating on the exact average. Being slightly below average for your age does not necessarily indicate a problem — it gives your doctor useful planning information.

• Above average for your age: suggests strong ovarian reserve. Very high (>5.0 ng/mL) may indicate PCOS.
• Average for your age: your ovarian reserve is typical — reassuring for fertility potential.
• Below average for your age: may suggest diminished ovarian reserve, but does not mean pregnancy is impossible.
• Significantly below average: consider consulting a reproductive endocrinologist sooner rather than later.

What Is a Good AMH Level to Get Pregnant?

There is no single AMH number that determines whether you can conceive. AMH measures how many eggs you have left, not the quality of those eggs or whether you will ovulate normally. Many women with low AMH conceive naturally, and women with normal AMH can still struggle if egg quality, ovulation, sperm, or tubal factors are involved. That said, here is how fertility specialists generally interpret AMH in the context of trying to conceive:

• AMH 1.5–4.0 ng/mL (any age): generally considered a 'good' level supporting natural conception
• AMH 1.0–1.5 ng/mL: adequate, particularly if you are under 35; do not delay if conception is the goal
• AMH 0.5–1.0 ng/mL: low; conception is still possible but the window is narrowing — specialist evaluation recommended
• AMH <0.5 ng/mL: significantly diminished reserve; fertility evaluation should not be delayed
• AMH >4.0–5.0 ng/mL: high; may indicate PCOS, which can cause irregular ovulation and is treatable

Low AMH: What It Means and What to Do

A low AMH result understandably causes anxiety, but there are important reasons to keep perspective. Low AMH means fewer eggs remain — it does not mean the remaining eggs are poor quality, and it does not mean you cannot conceive. What matters most is acting promptly: ovarian reserve continues to decline, and earlier intervention almost always yields better outcomes.

• Natural conception is still possible with low AMH, especially under 38
• IVF with low AMH usually yields fewer eggs per cycle, but egg quality can still be excellent
• Mini-IVF or 'duo-stim' protocols are designed specifically for low ovarian reserve
• Egg or embryo banking across multiple cycles is sometimes recommended
• Supplements such as CoQ10, vitamin D (if deficient), and DHEA may support egg quality — discuss with your doctor
• Do not retest endlessly hoping for a different number; act on the trend, not the noise

Why AMH Declines With Age

Women are born with all the eggs they will ever have — roughly 1–2 million at birth. By puberty, this drops to about 300,000–400,000. Each month, a group of follicles is recruited and most are lost through a natural process called atresia. AMH is produced by the growing follicles, so as the total egg supply decreases, AMH levels fall accordingly. This decline accelerates after age 35.

AMH by Age: What It Means for IVF

Fertility specialists use your AMH relative to your age to predict how your ovaries will respond to IVF stimulation medications. This helps them choose the right protocol and set realistic expectations for egg retrieval.

• High AMH for age (>75th percentile): likely strong responder — expect more eggs. Lower medication doses may be used to reduce OHSS risk.
• Average AMH for age (25th-75th percentile): standard stimulation protocol, typical egg yield expected.
• Low AMH for age (<25th percentile): may need higher doses or more aggressive protocols. Fewer eggs expected but quality can still be excellent.
• Very low AMH for age (<10th percentile): mini-IVF or natural cycle IVF may be considered; egg banking across multiple cycles is sometimes recommended.

Units Matter: ng/mL vs pmol/L

AMH results can be reported in two different units depending on your laboratory. To convert: 1 ng/mL = 7.14 pmol/L. For example, an AMH of 2.0 ng/mL equals 14.28 pmol/L. The chart above uses ng/mL, which is most common in North America. European and Australian labs often use pmol/L.

• High: >28.6 pmol/L (>4.0 ng/mL)
• Normal: 7.14–28.6 pmol/L (1.0–4.0 ng/mL)
• Low-normal: 5.0–7.14 pmol/L (0.7–1.0 ng/mL)
• Low: 2.14–5.0 pmol/L (0.3–0.7 ng/mL)
• Very low: <2.14 pmol/L (<0.3 ng/mL)

Can You Improve Your AMH Level?

AMH reflects the number of remaining follicles, and there is no proven way to increase your actual egg supply. However, some research suggests that certain supplements — DHEA, CoQ10, and vitamin D, particularly if you are deficient — may support follicular health and modestly improve AMH readings. The most important action if AMH is low is not to delay fertility evaluation.

Key takeaways

• AMH is Anti-Müllerian Hormone — a blood marker of ovarian reserve (egg quantity)
• AMH naturally declines with age — compare your result to your specific age group, not a single 'normal' number
• AMH measures egg quantity, not quality — age remains the strongest predictor of egg quality
• There is no single 'good' AMH for pregnancy — context (age, AFC, ovulation, sperm) matters more
• Low AMH does not mean you cannot conceive; it means earlier action is better than waiting
• Very high AMH (>5.0 ng/mL) often signals PCOS, which is treatable
• AMH can be tested any day of your cycle; both ng/mL and pmol/L are valid units
• Hormonal contraceptives can temporarily lower AMH; retest 2–3 months after stopping for an accurate reading
