Anti-Mullerian Hormone, or AMH test, is one of the most common tests ordered in a fertility evaluation. It measures the number of small follicles actively growing in your ovaries, giving an indication of your remaining egg supply. At CIMAR The Women's Hospital, Kochi, AMH is one of the first investigations I discuss with patients — and it is also one of the most misunderstood. A number on a report is not a verdict on your fertility.
What Does AMH Actually Tell Us?
AMH reflects your ovarian reserve — the quantity of eggs remaining. It does not measure egg quality. It does not tell us whether your fallopian tubes are open, whether ovulation is occurring normally, or whether a pregnancy is possible. A low AMH result in a 28-year-old carries very different implications from the same result in a 42-year-old. Age, menstrual history, antral follicle count on ultrasound, and your partner's semen analysis are all essential parts of the picture. AMH is one piece of information, not the whole story.
What Are the Reference Ranges for AMH?
There is no single normal value for all women. AMH declines naturally with age. As a general guide used by fertility clinics in India, values above 3.5 ng/mL suggest a high ovarian reserve, sometimes seen with PCOS. Values between 1.0 and 3.5 ng/mL are considered normal. Values between 0.5 and 1.0 ng/mL indicate low AMH, and values below 0.5 ng/mL indicate a very low reserve. A high AMH is not always straightforward either — it may indicate PCOS and can increase the risk of ovarian hyperstimulation if fertility treatment is not carefully planned.
Can AMH Be Improved?
No. AMH levels cannot be meaningfully changed by supplements or lifestyle modification. Many products claim to improve ovarian reserve — the evidence does not support this. What you can do is act on the information your AMH gives you. If your AMH is low, the most important thing is not to delay. Seeking a fertility evaluation early, understanding your full picture, and discussing your options with a specialist gives you the most choices. If you are not ready to conceive now but want children in the future, fertility preservation through egg freezing is worth discussing
What Should You Do If Your AMH Is Low?
The answer depends on your age and circumstances. If you are in your twenties with a low AMH, you have the advantage of age — egg quality at this stage is generally good, and many women with low AMH conceive naturally or with minimal intervention. If you are in your thirties, a complete fertility specialist evaluation without delay is the right step. If you are in your forties, time matters — I recommend seeing a fertility specialist as soon as possible rather than waiting to see if natural conception occurs. In all cases, a low AMH is the beginning of a conversation, not the end of one.
FREQUENTLY ASKED QUESTIONS
What Is Anti-Mullerian Hormone (AMH)?
AMH is a hormone released by the small follicles in the ovary. It gives an indication of the number of remaining follicles and eggs in your ovary.
Why Am I Being Advised to Have an AMH Assessment?
The number of eggs present in the ovary declines as you age, until the menopause, when the supply runs out. The AMH results will enable your fertility specialist to advise you about your fertility potential, best treatment option and success rate.
What Factors Affect AMH Levels?
If you have polycystic ovaries, more small follicles are growing in your ovaries, making it likely that you will respond vigorously to stimulation drugs — your AMH levels may be higher. If you have a low number of growing follicles due to previous illness, pelvic operations, chemotherapy, or approaching menopause, this will be identified from AMH results.
I Have Had an AMH Assessment Before. Why Am I Advised to Have It Again?
Your AMH level changes over time, so a result from the last 12 months is most useful. Different laboratories also use different testing methods — repeating the test at the same clinic ensures the most accurate and consistent interpretation.
Can I Improve My AMH?
No. There is nothing you can do to change your AMH levels. Many supplements claim to increase AMH, but there is limited evidence that any supplement can meaningfully restore ovarian reserve. Discuss any supplement plan with your fertility specialist.
How and When Can I Have My AMH Tested?
AMH can be tested on any day of your menstrual cycle. It should be done at an accredited laboratory associated with a licensed fertility clinic for the most reliable result.
I Have Low AMH and I Am 30. What Should I Do?
Low AMH at 30 is concerning but does not mean you cannot get pregnant. AMH reflects egg quantity, not quality. Many women with low AMH conceive naturally at younger ages. Seek a complete fertility evaluation including antral follicle count, FSH, ovulation status, tubal assessment, and semen analysis. If you have been trying for six months or more without success, consult a fertility specialist without further delay.
I Am in My 20s and My AMH Is Low. What Should I Do?
Being in your 20s is a favourable factor even when AMH is low. See a gynaecologist or fertility specialist for a complete assessment — not just AMH alone. If you want a pregnancy now and have been trying unsuccessfully, seek fertility care. If you are not planning pregnancy yet but want children in the future, discuss fertility preservation options with a specialist.
I Am in My 40s and My AMH Is Low. I Want to Get Pregnant. What Should I Do?
Do not delay. See a fertility specialist as soon as possible. At 40 and above egg quantity reduces. A reproductive endocrinologist will assess your AMH, antral follicle count, hormone levels, fallopian tube patency, and your partner's semen to determine the most appropriate path — which may include natural conception attempts, ovulation induction, IUI, or IVF. The combination of your exact age and AMH value together is far more informative than either number alone.
