AMH levels offer an estimate of the number of developing follicles in your ovaries, often called ovarian reserve. A low result can suggest that this pool is smaller than expected, but it does not by itself show whether you can become pregnant naturally, measure egg quality, or tell you when menopause will occur.
What AMH levels can tell you—and what they cannot
Anti-Müllerian hormone (AMH) is produced by cells around developing ovarian follicles. A blood test measures AMH as an indirect marker of the number of these follicles. It is a measure of quantity, not a count of every egg remaining. Ovarian reserve tests also have no universally accepted cutoff that separates “normal” from “abnormal,” so your result needs context, including your age and the laboratory’s reference range.
AMH is most useful in fertility treatment. It can help a clinic estimate how the ovaries may respond to stimulation for in vitro fertilization (IVF) or egg freezing, including the likely number of eggs retrieved. It does not measure egg health or guarantee how many eggs will lead to a pregnancy. Age remains an important factor in egg quality and treatment outcomes.
Why a low result does not predict natural conception
Natural conception depends on more than the number of developing follicles. AMH does not tell you whether an egg released in a particular cycle is capable of being fertilized, and a low result is not the same as infertility. Pregnancy can occur even when AMH is very low or undetectable.
A time-to-pregnancy cohort study of women aged 30 to 44 who had no history of infertility found that diminished ovarian reserve—defined in the study as AMH below 0.7 ng/mL—was not significantly associated with a higher risk of future infertility or lower chances of conceiving in a given cycle. This result applies to the women studied; it cannot predict an individual’s outcome or settle every fertility question. It does, however, show why a low AMH result alone should not be read as a verdict on natural conception.
AMH also does not show how quickly your ovarian reserve is changing. A single result is a snapshot, not a personal fertility countdown. Whether testing is useful depends on what decision you are trying to make; a result may have a different role during IVF planning than when you are simply curious about future fertility.
Can AMH predict when menopause will happen?
Lower AMH for a person’s age is associated with earlier menopause at a population level. That does not make it a precise clock for an individual. A 2023 systematic review by Scott M. Nelson and colleagues included 41 studies and 28,858 women. The studies generally linked lower age-specific AMH with earlier menopause, but estimates for women under 40 could span roughly 2 to 12 years. The prediction became more informative as menopause approached, when the time window was shorter.
In other words, a low result may be one clue about ovarian reserve, but it cannot reliably tell you the year menopause will begin. Routine AMH testing to predict menopause is not recommended in the review’s conclusions; research into its use for individual predictions remains ongoing.
Read your result in context
AMH varies with age, and people of the same age can have different results. Some circumstances can affect interpretation: polycystic ovary syndrome can raise AMH, while hormonal contraceptive use can temporarily lower it. One review notes that this temporary decrease may persist for up to two months after stopping hormonal contraception. Tell your clinician about relevant medications and health history when discussing a test.
If you are considering fertility treatment, ask how your result could affect expectations for ovarian stimulation—not whether it can promise pregnancy. If you are trying to conceive naturally or using a direct-to-consumer test, ask what the result can and cannot change about your next decision. AMH testing is not a diagnosis of infertility, and general-population testing is discouraged in US professional guidance because it does not reliably predict an individual’s fertility. Recommendations and access to testing may differ by country.
If a low result has worried you, or you have questions about fertility or menopause, discuss it with a qualified clinician who can interpret it alongside your age, menstrual history and reason for testing. Do not make major fertility decisions from an AMH number alone.
