Key takeaways

  • AMH (anti-Mullerian hormone) reflects your ovarian reserve — the quantity of eggs remaining — not egg quality and not your monthly chance of conceiving.
  • There is no single magic number. A "good" AMH is one that is normal for your age; AMH naturally falls as you get older.
  • For most reproductive-age women, AMH of about 1.0 to 4.0 ng/mL is considered normal. Above 4.0 often points to PCOS; below 1.0 suggests low reserve.
  • Low AMH does not mean infertile. Many women with low AMH conceive naturally — it may just take a little longer.
  • AMH is most useful for predicting how your ovaries will respond to IVF stimulation, and for fertility-preservation planning.
  • Always read your AMH alongside your age, cycle pattern, antral follicle count, and partner factors — never in isolation.

What AMH actually measures

Anti-Mullerian hormone (AMH), sometimes called Mullerian-inhibiting substance, is a protein made by the granulosa cells lining small antral follicles (about 2 to 9 mm) in your ovaries. The amount of AMH in your blood mirrors the size of this small-follicle pool, which in turn reflects your overall ovarian reserve — the number of eggs you have left.

Unlike FSH and oestradiol, AMH stays fairly steady across the menstrual cycle, because antral follicles produce it continuously rather than in response to monthly hormone swings. That is why AMH can be tested on any day of your cycle, with no fasting and no special prep — one reason it has become the most commonly ordered ovarian-reserve test in fertility clinics.

Here is the crucial caveat: AMH measures quantity, not quality. Egg quality — how likely an egg is to make a healthy, chromosomally normal embryo — is a separate dimension that depends mostly on age. A woman with plenty of eggs but poorer quality may struggle to conceive, while a woman with few eggs of good quality may conceive readily. AMH also tells you nothing about whether your tubes are open, your uterus is healthy, you are ovulating, or your partner's sperm is normal. It is one input among many, not a verdict.

A few things can temporarily lower your AMH reading: hormonal contraception (by roughly 20 to 30 percent on average), GnRH-agonist treatment, pregnancy, and recent ovarian surgery. Severe vitamin D deficiency and BMI extremes may have mild effects too. If any of these apply to you, mention them when your result is interpreted.

Good AMH levels by age: Indian reference ranges

There is no universal "good" AMH number, because what is healthy at 25 is not the same as what is healthy at 38. AMH declines gradually through your 20s and early 30s, falls faster from your mid-30s, and approaches zero in the years before menopause. Indian women tend to average slightly lower AMH than Western women, consistent with the earlier average menopause age in India (around 46 to 48 years per ICMR data, versus about 51 in the West).

As a broad guide, typical AMH averages reported by large Indian fertility networks are:

How to read your number

For everyday clinical interpretation, fertility specialists in India generally use these broad bands (read alongside your age):

  • 1.0 to 4.0 ng/mL — normal ovarian reserve for a reproductive-age woman.
  • Above 4.0 ng/mL — often suggests polycystic ovary syndrome (PCOS) or polycystic ovarian morphology; values above 6.0 ng/mL strongly point to PCOS in the right clinical context.
  • Below 1.0 ng/mL — low ovarian reserve.
  • Below 0.5 ng/mL — very low reserve, which warrants a fertility consultation soon.

Two practical reminders. First, labs and assays differ. SRL, Metropolis, Thyrocare, Dr Lal PathLabs and fertility-clinic labs each use their own assay (commonly Beckman Coulter or Roche) and reference range, and values can vary by 10 to 30 percent between assays. Always compare your number to the reference range printed on your own report, and use the same lab if you re-test. Second, a single markedly low result is worth confirming with a repeat test in 2 to 3 months — normal cycle-to-cycle variation of 10 to 20 percent means one low reading isn't always the final word.

Why low AMH does not mean you can't get pregnant

This is the part most women come looking for, so let's be clear. AMH is a weak predictor of natural conception in any given cycle. Your monthly chance of conceiving is driven far more by your age, whether you ovulate regularly, the health of your tubes and uterus, your partner's sperm, and your timing — not by your AMH number.

Studies of women with diminished ovarian reserve show that low AMH can reduce the per-cycle odds and may mean it takes a few more months, but the cumulative one-year conception rate is often similar to age-matched peers — especially when AMH is mildly or moderately reduced rather than very low. In other words, low AMH usually means "you may have less time and may need to be more deliberate," not "you cannot conceive."

What genuinely moves the needle on natural conception is in your hands more than your AMH is. Confirming you ovulate (with an ovulation test kit or by tracking your cervical mucus for TTC), timing intercourse to your fertile window, and the basics — healthy weight, not smoking, good sleep and starting folic acid before conception — all support per-cycle odds. None of these change your AMH meaningfully, but together they matter more than the number on the report. Our broader trying to conceive 101 guide walks through the full picture.

Remember too that fertility is a couple's equation. Male factor contributes to roughly 40 to 50 percent of infertility in India, so a semen (sperm) analysis is a standard, low-cost early step. Open tubes are also essential and are not shown by AMH — that is assessed with an HSG tubal-patency test.

What high AMH means (and when it signals PCOS)

A high AMH is not a fertility jackpot. AMH above about 4.5 ng/mL often reflects polycystic ovarian morphology — ovaries carrying many small antral follicles, each adding to the AMH total. In Indian women with PCOS, AMH commonly sits between 5 and 10 ng/mL, and sometimes above 15.

The catch is that PCOS frequently comes with irregular or absent ovulation, and you cannot conceive in a cycle where you don't release an egg. So a large egg pool does not translate into easy conception when ovulation is unreliable. The encouraging news is that ovulation can usually be restored — letrozole (the FOGSI first-line) or clomiphene helps many women ovulate, and modest weight loss plus addressing insulin resistance improves cycle quality. Our guide to PCOS fertility treatment and PCOS and pregnancy cover this in detail.

One genuine upside: women with PCOS tend to have a longer reproductive lifespan and slightly later menopause, so their reserve lasts a bit longer than average — even if the cycle irregularity makes the timing trickier.

AMH and IVF: where the number really counts

AMH is the single best predictor of how your ovaries will respond to IVF stimulation — far more useful here than for natural conception. Broadly, the number of eggs retrieved tracks with your starting AMH:

  • AMH above ~3.5 ng/mL: high responder (often 15–25 eggs), with a higher risk of ovarian hyperstimulation syndrome (OHSS) needing careful protocol selection.
  • AMH ~2.0–3.5 ng/mL: good responder (roughly 12–20 eggs).
  • AMH ~1.0–2.0 ng/mL: moderate responder (roughly 6–12 eggs).
  • AMH ~0.5–1.0 ng/mL: poor responder (often 3–6 eggs).
  • AMH below ~0.5 ng/mL: very poor responder (often 1–3 eggs, sometimes cycle cancellation).

But egg quality — and therefore live-birth rates — still depends mainly on age, not AMH. A 30-year-old with low AMH may retrieve few eggs that are nonetheless good quality; a 40-year-old with normal AMH may retrieve many eggs of lower quality. That is why age, not AMH, remains the strongest driver of IVF success. For women with very low AMH and limited time, donor-egg IVF (which uses young donor eggs) keeps live-birth rates high regardless of the recipient's AMH. See our guides to IVF in India: cost and success rates, IUI vs IVF, and donor-egg IVF and the ART Act 2021.

AMH and fertility preservation (egg freezing)

If you are thinking about freezing eggs, AMH is one of the most useful numbers you can have, because it predicts how many eggs you are likely to retrieve per cycle — and therefore how many cycles you may need to bank a target of roughly 15 to 20 mature eggs. A woman with AMH above 3.5 ng/mL may reach that in one or two cycles; someone with AMH below 1.0 ng/mL may need three or more.

Age still rules quality, so freezing earlier generally yields better long-term odds: a batch of 15 to 20 eggs frozen at 32 gives roughly a 60 to 70 percent chance of at least one live birth later, falling to around 30 to 40 percent at 38. In India, an egg-freezing cycle runs about Rs 1.5 to 3 lakh plus annual storage, and the ART Act 2021 has clarified that single women can access these services. If you are weighing it up, see the best age to freeze eggs, how much it costs to freeze eggs, and our overview of egg freezing in India.

AMH alongside other fertility tests

AMH is most informative as part of a panel, not on its own. A thorough ovarian-reserve assessment pairs AMH with an antral follicle count (AFC) — a transvaginal ultrasound count of small follicles, usually on cycle day 2 to 5. Normal AFC is roughly 10 to 20 follicles in total; below 6 suggests very low reserve. Combined AMH plus AFC costs about Rs 2,500 to Rs 5,000 in India and gives a more reliable picture than either alone.

AMH myths vs facts

Myth: AMH predicts whether I can get pregnant naturally

  • Fact: AMH predicts egg quantity, not your per-cycle chance of natural conception.
  • Fact: Many women with low AMH conceive naturally; many with normal AMH face other hurdles.
  • Fact: Age, ovulation, tubes, uterus and partner sperm matter more for natural conception.
  • Fact: AMH is most predictive for IVF response, far less so for natural conception.

Myth: Low AMH means I am infertile

  • Fact: Low AMH means reduced reserve, not infertility.
  • Fact: Per-cycle odds may dip, but cumulative one-year rates can match age-matched peers.
  • Fact: IVF with your own eggs is still possible at most low-AMH levels, just with fewer eggs per cycle.
  • Fact: Very low AMH (below 0.5 ng/mL) needs prompt review but does not rule out conception.

Myth: High AMH means I'll conceive easily

  • Fact: High AMH (above ~4.5 ng/mL) often signals PCOS, which has its own challenges.
  • Fact: PCOS-related ovulation problems can reduce fertility despite a large egg pool.
  • Fact: AMH measures quantity, not quality — quality depends mostly on age.
  • Fact: High AMH with regular cycles is favourable; with a PCOS phenotype it needs specific management.

Myth: AMH never changes, so I only need to test once

  • Fact: AMH declines with age in a predictable but individual pattern.
  • Fact: Serial testing every 1 to 2 years tracks your trajectory and informs planning.
  • Fact: Cycle-to-cycle variation of 10 to 20 percent is normal; confirm a markedly low value with a repeat test.
  • Fact: Contraception, GnRH agonists, pregnancy and ovarian surgery can all shift AMH temporarily.

Frequently asked questions

What is a good AMH level to get pregnant?

There is no single number — a "good" AMH is one that is normal for your age. For most reproductive-age women, roughly 1.0 to 4.0 ng/mL is considered normal. But AMH only reflects egg quantity, so a normal value is reassuring without guaranteeing conception, and a lower value does not rule it out. Always interpret it alongside your age, cycle pattern and other tests.

Can I get pregnant with a low AMH?

Yes. Low AMH means fewer eggs in reserve, not infertility. Many women with low AMH conceive naturally; it may simply take a few more cycles. AMH is a weak predictor of natural conception in any given month — your age, ovulation, tubes, uterus and partner's sperm matter more. Very low AMH (below 0.5 ng/mL) is worth discussing with a fertility specialist soon, but it still does not mean pregnancy is impossible.

Does a high AMH mean better fertility?

Not necessarily. High AMH (above about 4.5 ng/mL) often points to PCOS or polycystic ovarian morphology. While it reflects a large egg pool, PCOS frequently brings irregular ovulation, which can make conceiving harder despite the high number. The good news is that ovulation can usually be restored with treatment such as letrozole.

Can AMH be improved or increased?

No reliable treatment or supplement durably raises AMH, because it reflects the size of your remaining follicle pool. Some readings are temporarily lowered by hormonal contraception, recent ovarian surgery or severe vitamin D deficiency, and may rise modestly once those resolve, but you cannot meaningfully "boost" your true reserve. The useful focus is optimising the things you can change — ovulation, weight, timing and overall health.

On which day of the cycle should AMH be tested, and what does it cost in India?

AMH is stable across the cycle, so it can be tested on any day with no fasting. In India it costs roughly Rs 1,500 to Rs 3,500 at major labs, or about Rs 2,500 to Rs 5,000 when combined with an antral follicle count ultrasound, which is the more informative combination.
