The short answer

Anti-Müllerian hormone (AMH) estimates ovarian reserve, which is the quantity of eggs remaining in the ovaries. It does not reliably predict natural conception, time to pregnancy, pregnancy, or live birth, but it can help estimate ovarian response and egg (oocyte) yield during assisted treatment such as IVF. Ovarian reserve tests are much better at estimating egg quantity and ovarian response than egg quality or reproductive potential. ACOG and the American Society for Reproductive Medicine (ASRM) both caution against using one AMH result to predict pregnancy.

A low AMH result in someone who is not seeking pregnancy generally does not require action. If an individual result needs interpretation, including a low result, discuss it with a clinician. AMH can be elevated in polycystic ovary syndrome (PCOS), and hormonal contraception can lower the measured result. These factors can make a number look different from the age values below. 2023 international PCOS guideline. ASRM hormonal contraception committee opinion.

Published AMH levels by age

The table shows median AMH and the interquartile range, from the 25th to 75th percentile, in ng/mL. It reproduces Table 2 from a 2025 peer-reviewed study at Bursa Uludag University, a tertiary hospital in Turkey. The subgroup included 14,029 women ages 18 to 45 after the authors excluded patients tested through assisted-reproduction, reproductive-endocrinology and infertility, and endometriosis units. Most remaining patients came from the gynecology clinic, with others from departments including endocrinology, dermatology, and internal medicine. This is a mixed clinical population, not a randomly sampled general or proven-fertile population. 2025 AMH nomogram study, Table 2.

Every sample was measured with the Beckman Coulter Access II enzymatic immunoassay. These are the publication’s descriptive values, not Mito reference ranges, diagnostic cutoffs, or targets to hit.

AMH assays are not interchangeable. Different methods, calibration systems, and study populations can produce different values. Use the reference interval on your own laboratory report rather than treating this study’s middle 50 percent as your personal normal range. ASRM ovarian reserve committee opinion.

What AMH says about ovarian reserve

AMH is produced by cells around small, developing ovarian follicles. Because those follicles are part of the remaining follicle pool, the blood level provides an estimate of egg quantity. It does not count eggs directly. See the AMH biomarker overview for more about how the hormone is produced. ACOG.

Egg quantity and egg quality are different questions. AMH and antral follicle count can help estimate quantitative ovarian response, while age remains a stronger predictor of reproductive success than ovarian reserve itself. AMH should not be interpreted as a stand-alone measure of egg quality or the ability to conceive. ASRM ovarian reserve committee opinion.

Why AMH generally changes with age

The pool of ovarian follicles decreases over time, so AMH generally declines with age. The pattern is not a smooth rule for every person. In the published table, nearby ages sometimes have the same median or a small reversal, which is why one row should not be treated as a personal target. The study reported an overall inverse relationship between age and AMH, but its cross-sectional values compare different people rather than tracking one person’s change over time. 2025 AMH nomogram study.

How PCOS and hormonal contraception affect the number

AMH can be elevated in adults with PCOS because it reflects the larger number of small follicles often seen with polycystic ovarian morphology. The 2023 international guideline allows AMH as an alternative to ultrasound for defining polycystic ovarian morphology in adults, but says AMH should not be used as a single test to diagnose PCOS. Age, cycle pattern, symptoms, assay, and other causes still matter. 2023 international PCOS guideline.

Current or recent hormonal contraception can suppress measured AMH. ASRM advises interpreting ovarian reserve markers cautiously during hormonal contraceptive use. Do not compare a result with the published table without accounting for that context. ASRM hormonal contraception committee opinion.

How AMH fits with other hormone tests

AMH is one part of hormone evaluation. Follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol answer different questions and can depend more on cycle timing. Our guide to female hormone testing explains how these measurements fit together.

What to do with your AMH result

Start with the method, units, and reference interval printed on your own laboratory report. If an individual result needs interpretation, including a low result, see a clinician. A low AMH result in someone who is not seeking pregnancy generally does not require action.

If you are deciding whether to measure AMH, Mito members can order an AMH blood test at cost. The product page has current availability and test details. For the separate question of whether habits or supplements can alter the marker, read the guide to improving AMH.
