AMH Levels by Age: Chart, Averages and What They Actually Mean

Your anti-Müllerian hormone (AMH) level is one of the most common numbers in fertility care — and one of the most misunderstood. The chart below shows how AMH levels change by age, from 24 to 50. The curve is modeled on the age-related decline reported by Seifer and colleagues in a study of 17,120 women presenting to fertility centers across the United States.

I’m Dr. Lucky Sekhon, a double board-certified OBGYN and Reproductive Endocrinologist & Infertility specialist practicing at RMA of New York. I order this test every day, and I spend just as much time explaining what it doesn’t tell you. Find your age on the chart, plot your own result against it, and then read on — because the number by itself is the least interesting part.

What AMH actually measures

AMH is made by the small, resting follicles sitting in your ovaries right now. The more of those follicles you have, the more AMH shows up in your blood. That makes it a reasonable proxy for ovarian reserve — roughly, how many eggs are left in the tank.

What it does not measure is egg quality. It doesn’t measure whether you ovulate, whether your tubes are open, or whether your partner’s sperm will fertilize anything. It is one number describing one thing: quantity.

How to read the chart

The solid line is the average (mean) AMH at each age. The shaded band around it is one standard deviation either side — a rough picture of how widely real people scatter around that average. Both are modeled: a smooth curve fitted to the published rate of decline, rather than a year-by-year readout of any single dataset.

Two things jump out. First, the line falls steadily with age — by roughly 0.2 ng/mL a year through the twenties and into the early thirties, easing to about 0.1 ng/mL a year from the late thirties onward. Second, the band is enormous. At age 30 the modeled spread runs from about 0.5 to 5.1 ng/mL. Two women the same age, both entirely ordinary, can sit ten times apart.

Why the range is so wide

AMH is not normally distributed — it’s right-skewed, with a long tail of high values pulling the average upward. That means the mean sits above what a typical person actually has, and a “mean ± 1 SD” band is a rough guide to spread rather than a clinical cut-off. At older ages the lower edge of that band runs close to zero, which is a limitation of the arithmetic, not a finding about you.

This is exactly why I discourage patients from treating a single AMH result as a verdict. It is a data point on a very wide distribution.

What your AMH level cannot tell you

This is the part I wish were printed on every lab slip.

It cannot tell you whether you can get pregnant naturally. A 2017 JAMA study of women aged 30–44 without a history of infertility found that women with low AMH were no less likely to conceive than women with normal levels. The authors concluded the data “do not support the use of…antimüllerian hormone levels to assess natural fertility.” I’ve written more about why your AMH level is not a fertility test.

It cannot reliably tell you when you’ll reach menopause. ACOG Committee Opinion No. 773 is explicit that more data are needed before AMH can be used to predict time to menopause, and that a single AMH level in a woman with presumed fertility “does not appear to be useful in predicting time to pregnancy.”

It cannot tell you your odds of a live birth from IVF. A large individual-patient-data analysis in Human Reproduction Update found that ovarian reserve tests add essentially nothing to age alone when predicting ongoing pregnancy after IVF.

And because it changes so little of substance month to month, checking your AMH over and over tends to generate anxiety rather than information.

What a low AMH level means

A low AMH suggests fewer eggs remaining, which usually means fewer eggs retrieved in an IVF or egg freezing cycle. That is genuinely useful for planning: it shapes the medication dose, the expected yield, and whether more than one cycle is likely.

What it does not mean is that you are infertile. I have had patients with very low AMH conceive on their own, and patients with reassuring numbers who struggled. If you are weighing treatment options with a low number, I’ve written about choosing between IVF and IUI when your AMH is low.

What a high AMH level means

Higher-than-average AMH often reflects a large pool of resting follicles, which is characteristic of polycystic ovary syndrome. In a stimulation cycle it can predict a strong — sometimes excessive — response, which matters for dosing and for avoiding ovarian hyperstimulation. It is something to flag to your doctor before you start, not something to worry about in isolation.

A note on units

This chart uses ng/mL, the standard in the United States. Many labs elsewhere report pmol/L. To convert, divide pmol/L by 7.14 — so 21.4 pmol/L is roughly 3.0 ng/mL. Comparing a pmol/L result directly against this chart will make your number look alarmingly high.

When AMH testing is genuinely useful

AMH earns its place when there is a decision attached to it: planning an egg freezing or IVF cycle, choosing a stimulation protocol and dose, or investigating suspected PCOS or diminished ovarian reserve. Paired with an antral follicle count, it gives a reasonable estimate of how your ovaries will respond to stimulation.

If you are thinking about freezing your eggs, my egg freezing success calculator models likely outcomes by age and egg number. If you are already in an IVF cycle, the embryo grading chart and the euploid embryo predictor may be more directly useful than anything AMH can tell you now.

Questions worth asking your doctor

Given my AMH and antral follicle count, how many eggs would you expect to retrieve? Does this change the protocol you’d recommend? Is there anything here that changes the timeline I should be planning around? And — the one people forget — does this number change what you would advise me to do differently?
