If you have attended a fertility consultation, your AMH (Anti-Müllerian Hormone) level has almost certainly been discussed. For many patients, this single number becomes a source of enormous anxiety — either because it is lower than expected or because it is abnormally high. But AMH is frequently misunderstood, both in what it measures and in what it actually predicts.

This blog explains AMH in plain terms — what it is, what it means, how it affects IVF treatment, and — crucially — what it does not tell you.

What Is AMH and What Does It Measure?

Anti-Müllerian Hormone is a glycoprotein produced by the granulosa cells that surround each developing follicle in the ovaries. Specifically, it is produced by small, early-stage follicles called preantral and early antral follicles — those that have begun growing but have not yet been selected for dominance and ovulation.

Because AMH is produced throughout the year (unlike FSH and oestradiol, which fluctuate with the menstrual cycle), it can be measured on any day and provides a relatively stable, cycle-independent estimate of the ovarian reserve — the number of remaining primordial follicles in the ovaries.

Higher AMH generally indicates a larger pool of available follicles. Lower AMH suggests a smaller pool. But AMH does not directly measure egg quality — and this distinction is critically important.

AMH Reference Ranges by Age

The following ranges represent general clinical guidelines. Your individual result should always be interpreted by your fertility specialist in the context of your age, AFC, clinical history, and other hormonal results.

Under 35 years: 1.5–4.0 ng/mL — normal to good ovarian reserve

35–37 years: 1.0–1.5 ng/mL — acceptable, slight decline expected

38–40 years: 0.7–1.0 ng/mL — low-normal range

Over 40 years: Below 0.5 ng/mL — low ovarian reserve, but IVF is often still possible

Above 4.0–5.0 ng/mL: High reserve — often associated with PCOS; increases OHSS risk

Note that laboratory assay methods differ between countries and centres. A result from one laboratory may not be directly comparable to a result from another. Your fertility specialist will interpret your result in the context of their specific laboratory's reference range.

What Does Low AMH Mean for IVF?

A low AMH level tells your fertility specialist that your ovaries are likely to produce fewer eggs in response to stimulation than a patient with normal AMH. This has several clinical implications:

Higher doses of gonadotropin medications may be needed to maximise follicle recruitment

Fewer eggs may be available at retrieval — sometimes only 1 to 5

There may be fewer embryos to choose from, and banking embryos over multiple cycles may be recommended

The risk of a poor response or cancelled cycle is higher

What low AMH does NOT mean:

That the eggs you have are poor quality — AMH measures quantity, not quality

That IVF cannot succeed — many women with very low AMH (below 0.5 ng/mL) have successfully conceived

That natural conception is impossible

That you are in menopause or approaching it

Egg quality is primarily determined by age. A 33-year-old woman with a low AMH still has the egg quality of a 33-year-old — and that quality is inherently better than that of a 40-year-old with a normal AMH. This is one of the most important messages in fertility medicine.

Can You Still Do IVF With a Low AMH?

Absolutely yes. Low AMH changes the strategy, not the possibility. Protocol modifications for low ovarian reserve include:

Maximum dose gonadotropin stimulation to recruit every available follicle

Luteal phase stimulation or dual stimulation (DuoStim) to bank embryos from two retrievals within a single menstrual cycle

DHEA supplementation (25–75 mg/day for 3–6 months under medical supervision) — some evidence suggests modest improvement in ovarian response in low-reserve patients

CoQ10 supplementation (400–600 mg Ubiquinol daily) — may improve mitochondrial function in remaining eggs

Natural cycle IVF — for very low responders, stimulation may be avoided entirely, and the naturally selected single follicle retrieved

Consideration of oocyte (egg) donation — if multiple cycles with own eggs have been unsuccessful, this offers very high success rates

What Does High AMH Mean?

High AMH (above 4.0–5.0 ng/mL) indicates a large pool of resting follicles. While this sounds advantageous, it is most commonly associated with Polycystic Ovary Syndrome (PCOS) — a condition where large numbers of small follicles develop but ovulation is irregular or absent.

The main risks of high AMH in IVF:

High risk of Ovarian Hyperstimulation Syndrome (OHSS) — the ovaries may over-respond dramatically to stimulation medications

Need for lower, more cautious stimulation doses

Increased likelihood of a freeze-all cycle strategy

Potential for egg quantity but lower egg quality (particularly in PCOS)

High AMH is not a simple fertility advantage — it requires careful protocol design and expert management.

AMH and IVF Live Birth Rate: What the Research Actually Shows

This is perhaps the most important point in this entire blog: research consistently shows that while AMH is a good predictor of ovarian response (how many eggs will be collected), it is a poor predictor of live birth rate per IVF cycle — particularly in younger women.

A landmark study published in JAMA (Journal of the American Medical Association) in 2017 followed women for 12 months and found no statistically significant difference in pregnancy rates between women with low AMH and women with normal AMH. Age remained the primary driver of IVF success. This finding has been replicated in multiple subsequent studies.

The clinical implication: if your AMH is low but you are young (under 38), your eggs may still be of excellent quality. Fewer eggs does not mean fewer chances — it means fewer attempts before you need to consider alternatives.

Tests Used Alongside AMH

AFC (Antral Follicle Count): Ultrasound count of small resting follicles at the start of the cycle. Generally considered the most reliable real-time measure of ovarian reserve. Should always be interpreted alongside AMH.

FSH (Follicle Stimulating Hormone): Measured on Day 2–3 of the cycle. High FSH (above 10 IU/L) suggests the pituitary is working hard to recruit follicles, indicating lower reserve. But FSH fluctuates significantly between cycles — a single normal result is reassuring, a single high result is not always definitive.

Oestradiol (E2) on Day 2–3: Provides context for FSH interpretation. High oestradiol with normal FSH may still indicate poor reserve.
