AMH Test: What Your Result Actually Means for Your Fertility
A gynecologist is talking with a woman about their treatment during an appointment in an examination room.
AMH — Anti-Müllerian Hormone — has become one of the most commonly ordered fertility tests in India, and one of the most frequently misunderstood. Women receive their result with a number and a reference range and often little explanation of what it actually means for their fertility, their options, or their urgency to act.
Dr. Shachi Singh, consultant gynaecologist and fertility specialist at Prakash Hospital, Sector 33, Noida, explains AMH comprehensively.
What AMH Measures
AMH is produced by the small antral and pre-antral follicles in the ovaries. These follicles are the pool from which eggs will be recruited each cycle. A higher AMH reflects a larger pool of remaining follicles — higher ovarian reserve. A lower AMH reflects a smaller pool — reduced reserve.
AMH is the best available blood marker of ovarian reserve — the size of the remaining egg pool. It does not directly measure egg quality.
Why AMH is useful:
- Stable throughout the menstrual cycle — can be tested on any cycle day
- Declines progressively with age in a more linear fashion than FSH or oestradiol
- Predicts response to ovarian stimulation in IVF — helps plan stimulation protocols
- Identifies women at risk of poor response (low AMH) or excessive response/OHSS (very high AMH, as in PCOS)
What the Numbers Mean
AMH reference ranges vary slightly between laboratories and assay types, but broadly:
| AMH Level (pmol/L) | Interpretation | |---|---| | Above 25 | High — typical of PCOS; may indicate risk of overstimulation | | 15 to 25 | Normal to high | | 7 to 15 | Normal | | 5 to 7 | Low normal — reduced reserve | | 2.2 to 5 | Low — consider acting sooner | | Below 2.2 | Very low — significantly reduced reserve |
Note: some labs report in ng/mL. Multiply ng/mL by 7.14 to convert to pmol/L approximately.
What Low AMH Does NOT Mean
This is the most important part — and the part most women are not told.
Low AMH does not mean you cannot conceive naturally. AMH reflects quantity, not quality. Women with low AMH conceive naturally every day. AMH predicts how the ovaries will respond to fertility treatment stimulation — it does not determine whether you can get pregnant without treatment.
Low AMH does not predict imminent menopause. A low AMH in a woman in her 30s does not mean she is about to stop having periods or enter menopause — it means she has fewer follicles remaining than average for her age, not that ovarian function will cease imminently.
Low AMH does not mean IVF will definitely fail. Even with a very low AMH, IVF can succeed — particularly when the few eggs retrieved are of good quality. Success with very low AMH requires realistic expectations and an experienced fertility team.
What High AMH Means
A very high AMH — typically above 25 to 30 pmol/L — is most commonly seen in women with PCOS. It reflects the large number of small antral follicles characteristic of polycystic ovaries. While high AMH might seem reassuring for fertility, it also signals PCOS-related ovulation dysfunction and elevated OHSS risk with fertility treatment stimulation.
AMH and Age Together: The Full Picture
AMH must always be interpreted in the context of age. An AMH of 8 pmol/L at age 38 carries different implications than the same level at age 28:
- At 28: lower than average but likely still years of reproductive potential ahead
- At 38: consistent with the expected decline for age — less time to act, but not a crisis
When to Get AMH Tested
- Before starting fertility treatment — to guide stimulation planning
- When considering egg freezing — to predict likely egg yield per cycle
- When there is a family history of early menopause
- When periods have become irregular in the 30s
- As part of a complete infertility workup
- After ovarian surgery (cystectomy) — to assess impact on reserve
