AMH Test (Anti-Müllerian Hormone): What It Shows About Ovarian Reserve

Direct answer

The AMH test is a simple blood test that measures anti-Müllerian hormone, produced by small growing follicles in the ovaries. AMH levels give an indirect estimate of ovarian reserve, roughly how many eggs remain, and help predict response to IVF stimulation. The AMH test does not measure egg quality and cannot predict whether pregnancy will happen.

Key takeaways

• The AMH test estimates egg quantity, not egg quality.
• The AMH test can be drawn on any day of the menstrual cycle.
• A low AMH result does not mean infertility, and a high AMH result does not mean easy conception.
• AMH supports a PCOS assessment but is not, on its own, a diagnosis of PCOS.
• AMH results must be read alongside age, antral follicle count, symptoms and history by the doctor who ordered the test.

At a glance

Also known as

• Anti-Müllerian hormone test, AMH blood test
• Müllerian inhibiting substance (MIS)
• ""Egg reserve test"", ""ovarian reserve test"", ""fertility hormone test""
• Commonly asked for in India as ""AMH level"", ""AMH ke liye blood test"", or ""egg count test""

What the AMH test is

Anti-Müllerian hormone is made by the granulosa cells of small preantral and early antral follicles in the ovary. The number of these follicles falls with age, so AMH concentration falls with age too. Because AMH comes from follicles that are not under strong month-to-month pituitary control, AMH stays relatively stable across the cycle, unlike FSH or oestradiol.

In people assigned male at birth and in children, AMH is used differently, mainly in assessing testicular tissue and disorders of sex development. Most patient queries, and the rest of this page, concern AMH as an ovarian reserve marker.

Why the AMH test is done

• Fertility assessment: to estimate ovarian reserve as part of a wider couple evaluation.
• IVF planning: AMH predicts how many eggs are likely to be retrieved and helps the clinician choose a stimulation dose and reduce the risk of ovarian hyperstimulation syndrome.
• Suspected PCOS: AMH is often raised because of the higher number of small follicles. Current diagnostic criteria for PCOS allow serum AMH to be used as an alternative to follicle counting on ultrasound in adults, but not in adolescents, and not as a standalone test.
• Before or after treatment that may affect the ovaries: chemotherapy, pelvic radiotherapy, ovarian cyst or endometrioma surgery.
• Suspected premature ovarian insufficiency in someone with irregular or absent periods.
• Granulosa cell tumour follow-up, where AMH can act as a tumour marker.

Who should get this test

• People trying to conceive without success for 12 months, or 6 months if aged over 35.
• Anyone starting IVF, IUI or ovulation induction, where dosing matters.
• People considering elective egg freezing or fertility preservation before cancer treatment or gonadotoxic therapy.
• People with irregular periods, acne or unwanted hair growth being evaluated for PCOS.
• People who have had ovarian surgery, endometriosis or a family history of early menopause.
• People under 40 whose periods have stopped or become very irregular.

Routine AMH testing is not recommended as a general ""fertility check"" for people who are not currently trying to conceive and have no risk factors, the result rarely changes what happens next and often causes unnecessary alarm.

What the AMH test cannot detect or exclude

• Egg quality. AMH says nothing about the chromosomal health of eggs. Age remains the strongest predictor of egg quality.
• Whether you can conceive naturally. AMH is a poor predictor of spontaneous pregnancy. People with low AMH do conceive naturally; people with high AMH sometimes do not.
• Time to menopause for an individual. AMH shifts probability across populations but cannot give a personal date.
• Tubal blockage, fibroids, endometriosis, adenomyosis or uterine problems. These need ultrasound, HSG/HyCoSy or laparoscopy.
• Ovulation. A normal AMH does not confirm you are ovulating.
• Male factor infertility, which accounts for a large share of couple infertility and needs a semen analysis.
• PCOS on its own. A raised AMH is not a diagnosis; a normal AMH does not exclude PCOS.

A normal AMH result describes what was measured in that sample. It does not exclude a fertility problem. If you are still not conceiving, or your symptoms continue, go back to your doctor rather than treating the number as final.

Related but different examinations

These tests answer different questions and are not ranked against each other. Which one comes first depends on the problem: absent periods usually leads with FSH, LH, prolactin and thyroid tests; a couple planning IVF usually needs AMH plus antral follicle count; suspected tubal disease after pelvic infection leads with tubal imaging. Also distinguish the AMH used for ovarian reserve from AMH measured in paediatric endocrinology for disorders of sex development, the interpretation is entirely different.

How to prepare for the AMH test

Preparation, sample handling and reporting practices are operational matters that differ between laboratories. Your own collection centre's written instructions take precedence over any general guidance.

• Fasting: usually not needed. If AMH is bundled with fasting sugar or lipids, follow the fasting instruction for those tests.
• Cycle day: generally any day. Some units still prefer early follicular sampling for consistency.
• Medicines: tell the requesting doctor and the lab about hormonal contraceptives, GnRH agonists or antagonists, and any fertility drugs. Do not stop or change a prescribed medicine to ""improve"" the result, speak to the prescriber first.
• Biotin supplements: high-dose biotin can interfere with some immunoassays. Mention any supplement, including gym and hair-growth products.
• Hydration and clothing: drink water normally and wear a sleeve that rolls up easily.

If you are pregnant or breastfeeding

AMH falls during pregnancy and the result does not reliably reflect your baseline reserve. Discuss timing with your doctor rather than testing during pregnancy.

If you are on hormonal contraception

Combined pills, the vaginal ring and some other hormonal methods can lower measured AMH. Tell the lab; your clinician may repeat the test after a break arranged with the prescriber.

If you are a child or adolescent

AMH is not used to diagnose PCOS in adolescents, because follicle numbers are naturally high in the years after menarche. Paediatric AMH testing has separate indications and should be interpreted by a paediatric endocrinologist.

If you have a bleeding disorder or take blood thinners

Tell the phlebotomist. Firmer, longer pressure over the puncture site may be needed.

What happens during the AMH test

A phlebotomist cleans a spot on the inner elbow, applies a tourniquet, and draws a small blood sample into a labelled tube. The tourniquet is released, the needle removed, and pressure applied. The sample is then centrifuged and analysed on an automated immunoassay platform.

How long the process takes

The blood draw itself takes about a minute; expect roughly 5-10 minutes at the collection counter including registration and post-draw pressure. You can return to normal activity immediately, including driving and work. Laboratory processing and reporting schedules differ between units, ask your collection centre when your report will be available.

Understanding your AMH report

AMH is reported in ng/mL or pmol/L. Always check which unit your report uses before comparing values, and note the reference interval printed on your own report, it belongs to the assay and platform that laboratory used.

There is no single universal ""normal AMH"". Interpretation depends on age, the assay used, whether you are on hormonal medication, and why the test was done. For that reason this page does not publish a numeric age-wise table: values from one assay cannot be safely mapped onto another, and published cut-offs used in IVF units are prognostic tools, not diagnoses. Your treating doctor will compare your value against the reference range on your report.

If your AMH is lower than expected for your age

A low result suggests a smaller pool of remaining follicles. In IVF it predicts fewer eggs retrieved. It does not mean you are infertile, does not date your menopause, and does not say anything about egg quality. Many people with low AMH conceive, particularly when younger. Results vary depending on individual clinical circumstances.

If your AMH is higher than expected

A high result often reflects many small follicles, as in PCOS. It can also flag a higher chance of an exaggerated response to ovarian stimulation, which is useful for planning IVF safely. A high AMH is not a guarantee of better fertility, and does not by itself diagnose PCOS.

If your AMH is very low or undetectable

This needs clinical context, not self-interpretation. In someone with absent periods under 40 it raises the possibility of primary ovarian insufficiency and prompts further hormone testing. In someone on a GnRH agonist, recently pregnant, or after ovarian surgery, it may be explained by that situation.

When AMH results can be misleading

Causes of a falsely lowered or under-representative result

• Combined hormonal contraceptives, the vaginal ring, or GnRH agonist therapy.
• Current or recent pregnancy and the early postpartum period.
• Recent chemotherapy, AMH may recover partially over months.
• Recent ovarian surgery, including cystectomy for endometrioma.
• Delayed separation of serum or poor sample handling.
• Smoking and vitamin D deficiency are associated with modestly lower levels.

Causes of a falsely raised or over-representative result

• PCOS, a genuine biological elevation, but easily misread as ""excellent fertility"".
• High-dose biotin supplementation interfering with certain immunoassays.
• Heterophile or anti-reagent antibodies causing assay interference.
• Granulosa cell tumour, which can raise AMH markedly.

Assay and laboratory variation

Different AMH platforms give different numbers on the same sample. Comparing an AMH from one lab with an AMH from another can create the illusion of a fall or rise that has not happened. Where serial monitoring matters, use the same laboratory.

Risks and safety

Venous blood sampling for AMH

Risks are small and mostly local: brief pain, bruising, light-headedness, and rarely a small haematoma or infection at the site. Multiple attempts may be needed if veins are difficult.

Psychological impact of the result

A number reported without context is a genuine harm. AMH results frequently cause distress out of proportion to their predictive value, particularly low results in people not yet trying to conceive. Arrange to discuss the result with the clinician who ordered it.

AMH combined with transvaginal ultrasound

Where the assessment includes a transvaginal scan, that is a separate examination with its own considerations, including discomfort and the need for consent. It is not part of the blood test.

Red flags: when to seek help

Emergency, seek care now

• Sudden severe one-sided pelvic pain with vomiting, fainting or fever, possible ovarian torsion or a ruptured cyst.
• During or after IVF stimulation: rapid abdominal swelling, severe breathlessness, markedly reduced urine output, or calf pain and swelling, possible severe ovarian hyperstimulation syndrome or clot.
• Heavy vaginal bleeding with dizziness or collapse.

Same day or next day

• Positive pregnancy test with pain or bleeding.
• Spreading redness, swelling or pus at the blood-draw site, or fever after the draw.
• Persistent vomiting and reducing urine output after fertility injections.

Routine appointment

• Periods that have stopped for three months or more, or become very irregular.
• Unexplained difficulty conceiving after 12 months, or 6 months if over 35.
• Hot flushes, night sweats or vaginal dryness before age 40.
• An AMH result you do not understand, or one that differs from a previous lab.

Special situations

PCOS

AMH is often raised in PCOS. PCOD is not a different disease from PCOS, the two terms refer to the same condition, and ""PCOD"" is simply older Indian usage. Diagnosis rests on irregular ovulation, clinical or biochemical hyperandrogenism, and follicle count or AMH, after excluding other causes such as thyroid disease, hyperprolactinaemia and adrenal disorders.

Before cancer treatment

AMH is used alongside age and planned treatment when counselling on fertility preservation. Do not let testing delay urgent oncology treatment, these decisions are made jointly by oncology and fertility teams.

Endometriosis and ovarian surgery

Endometriomas and their surgical removal can reduce AMH. A pre-operative AMH helps set expectations.

Approaching menopause

AMH declines as menopause approaches but cannot set an individual date, and is not used to confirm that menopause has occurred. That diagnosis is clinical, based on 12 months without periods.

Adolescents

AMH is not used for PCOS diagnosis in adolescents; irregular cycles are common in the first years after menarche.

Transgender and gender-diverse people

Testosterone therapy affects ovarian function and AMH interpretation. Discuss fertility preservation with a clinician experienced in gender-affirming care before starting or changing therapy.

The AMH test in the Indian context

• Availability and vocabulary. The AMH test is widely available across Indian laboratories and is often requested together with a ""USG pelvis"" or sonography for antral follicle count. Many patients know it as the ""egg reserve test"".
• Ultrasound and the law. Any ultrasound performed alongside fertility assessment falls under the PC-PNDT Act 1994. Sex determination of a foetus is illegal in India. Registered units display this notice and maintain statutory records.
• ART regulation. Fertility treatment in India is governed by the Assisted Reproductive Technology (Regulation) Act 2021 and the Surrogacy (Regulation) Act 2021, which set eligibility and consent requirements for IVF, donor gametes and surrogacy.
• Advertising law. The Drugs and Magic Remedies (Objectionable Advertisements) Act 1954 prohibits advertising remedies claiming to restore fertility or raise egg reserve. Treat any product promising to ""increase AMH"" with scepticism.
• Supplements and self-medication. Over-the-counter AYUSH, herbal and gym supplements are commonly used in India. Some contain high-dose biotin, which can interfere with immunoassays. Declare everything you take.
• Coexisting conditions. Iron-deficiency anaemia, thyroid disorders, vitamin D deficiency and thalassaemia trait are common in India and may need attention alongside a fertility workup. South Asians develop metabolic complications of PCOS at lower BMI than White European populations, so insulin resistance should be assessed even when weight appears unremarkable.
• Data protection. Reports and any online form you fill are personal health data handled under the Digital Personal Data Protection Act 2023.

Cost and insurance in India

AMH is priced as a specialised hormone immunoassay, so it usually costs more than routine hormone tests such as TSH or FSH. Prices differ substantially between cities, laboratories and package deals, so ask for the current rate before the draw.

Factors that affect the cost:

• Assay platform and whether the lab is NABL-accredited.
• Whether the AMH is standalone or part of a fertility panel with FSH, LH, oestradiol, prolactin and thyroid tests.
• Whether a transvaginal scan for antral follicle count is added.
• Home collection, urgent processing, city and tier of the facility.
• Whether the sample is referred out to a larger reference laboratory.

Insurance: In India, outpatient diagnostic tests for infertility evaluation are frequently excluded or subject to waiting periods under standard health insurance policies. Some corporate and top-up plans include OPD diagnostics or specified fertility benefits. Confirm coverage with your insurer or TPA in writing before testing, and keep the doctor's prescription for any reimbursement claim.

Myths and facts

Frequently asked questions

Can the AMH test tell me if I will get pregnant?

No. The AMH test estimates how many follicles remain, which helps predict the number of eggs collected in IVF. It does not measure egg quality, tubal function, the uterus or sperm, and it is a weak predictor of natural conception. Pregnancy chance is judged from the whole clinical picture.

Do I need to fast or test on a particular cycle day?

Usually neither. AMH stays fairly stable through the menstrual cycle and fasting is generally not required. If your AMH is bundled with fasting glucose or a lipid profile, follow the fasting rule for those. Always follow the written instructions from your own collection centre.

Will stopping my contraceptive pill change my AMH result?

Hormonal contraception can lower measured AMH, so the result may under-represent your reserve. Do not stop any prescribed contraceptive on your own. Speak to the prescriber, who can advise whether to test now with that context noted, or to repeat the test later.

Can anything increase my AMH level?

No treatment or supplement has been shown to enlarge the remaining follicle pool. Avoid products advertised as raising egg reserve; such claims are also restricted under Indian law. Stopping smoking and correcting vitamin D deficiency support reproductive health generally but should not be expected to move the number meaningfully.

My two AMH reports are very different. Why?

Different laboratories use different assay platforms, and the same sample can give different numbers on each. Sample handling, hormonal medication, recent pregnancy and recent ovarian surgery also affect results. Where AMH is being monitored over time, use the same laboratory and discuss both reports with your clinician.

Is AMH better than an FSH test or a follicle count?

None is universally superior; each answers a different question. AMH is cycle-independent and reflects the follicle pool. Day 2-3 FSH reflects pituitary drive and needs precise timing. Antral follicle count on transvaginal ultrasound gives a direct visual count but depends on the operator and equipment. Clinicians often combine them.

Is the AMH test useful for men or children?

AMH has different uses outside ovarian reserve. In infants and children it helps assess testicular tissue and disorders of sex development, and it is occasionally used in evaluating undescended or absent testes. Interpretation follows separate paediatric and endocrine criteria, not fertility reference ranges.

Should I get an AMH test just to check my fertility?

Not routinely. For someone with regular periods, no risk factors and no current plan to conceive, an AMH result rarely changes management and often causes unnecessary worry. AMH is most useful when there is difficulty conceiving, planned IVF, planned fertility preservation, suspected PCOS, or previous ovarian surgery or chemotherapy.

Can AMH confirm that I have reached menopause?

No. Menopause is a clinical diagnosis, made after 12 consecutive months without periods in the absence of another cause. AMH falls as menopause approaches and may be undetectable around it, but the test is not used to confirm menopause or to predict the exact year it will occur.
