Quick answer: AMH levels by age at Mayo Clinic Laboratories run 1.2 to 12 ng/mL for women aged 20 to 24, 0.89 to 9.9 ng/mL at 25 to 29, 0.58 to 8.1 ng/mL at 30 to 34, 0.15 to 7.5 ng/mL at 35 to 39, 0.03 to 5.5 ng/mL at 40 to 44 and under 2.6 ng/mL at 45 to 50. To convert ng/mL to pmol/L, multiply by 7.14. A high AMH for your age can be a sign of PCOS; a low one means fewer eggs remain, not that you cannot get pregnant.
AMH levels by age
Mayo Clinic Laboratories AMH reference values (upper limit only from 45; bar starts at 0). KK Women's and Children's Hospital lists near-identical ranges.
| Age (women) | AMH (ng/mL) | AMH (pmol/L, x 7.14) |
|---|---|---|
| 15 to 19 | 0.62 to 7.8 | 4.4 to 55.7 |
| 20 to 24 | 1.2 to 12 | 8.6 to 85.7 |
| 25 to 29 | 0.89 to 9.9 | 6.4 to 70.7 |
| 30 to 34 | 0.58 to 8.1 | 4.1 to 57.8 |
| 35 to 39 | 0.15 to 7.5 | 1.1 to 53.6 |
| 40 to 44 | 0.03 to 5.5 | 0.2 to 39.3 |
| 45 to 50 | Under 2.6 | Under 18.6 |
| 51 to 55 | Under 0.88 | Under 6.3 |
| Over 55 | Under 0.03 | Under 0.2 |
Mayo also lists AMH for males, where it is highest in infancy (18 to 283 ng/mL under age 2) and under 13 ng/mL after age 12. AMH assays differ, so compare repeat results from the same lab.
What AMH measures
Anti-Mullerian hormone is made by the small, early-stage follicles in the ovaries, so its level reflects how many follicles, and therefore eggs, remain: the ovarian reserve. The ASRM explains that AMH declines as follicles are used up with age. Unlike FSH and estradiol, AMH stays fairly steady through the menstrual cycle, so it can be tested on any day, and MedlinePlus says no special preparation is needed.
What AMH does not tell you
The ASRM's 2020 committee opinion says ovarian reserve markers such as AMH are useful for predicting how many eggs IVF stimulation will retrieve, but are poor predictors of reproductive potential independent of age. The evidence behind that:
- In the EAGER trial of 1,202 women aged 18 to 40, women with AMH under 1 ng/mL had similar cumulative pregnancy rates to women with 1.0 to 3.5 ng/mL.
- In the Time to Conceive study of women aged 30 to 44 without known infertility, AMH under 0.7 ng/mL did not lower cumulative pregnancy rates after 6 or 12 cycles of trying (Steiner et al, JAMA 2017).
- For IVF, very low AMH matters: in more than 5,000 cycles with AMH under 0.16 ng/mL, 54% were canceled and the live birth rate was 9.5% per cycle started (ASRM).
MedlinePlus adds that a low AMH may mean menopause is approaching, but cannot predict when. In women under 40 with menopause symptoms, an AMH well below average for age may point to primary ovarian insufficiency, which needs a doctor.
High AMH and PCOS
Women with polycystic ovary syndrome have many small follicles, so their AMH is often high. The 2023 international PCOS guideline allows AMH as an alternative to ultrasound for the polycystic-ovary criterion, in adults only. MedlinePlus stresses that AMH alone cannot diagnose PCOS: doctors combine it with symptoms, androgen tests such as the free androgen index and medical history. See our PCOS blood test guide.
Worked example
A 36-year-old planning a family in two years gets an AMH of 1.1 ng/mL (1.1 x 7.14 = 7.9 pmol/L). That is inside Mayo's 0.15 to 7.5 range for 35 to 39, toward the lower end. On the Time to Conceive data, it does not mean she will struggle to conceive naturally. It does suggest fewer eggs would be retrieved if she chose egg freezing or IVF, which is the real use of the number, so it is worth discussing timing with a fertility doctor.
A 27-year-old with irregular periods and acne gets an AMH of 11 ng/mL (78.5 pmol/L), above Mayo's 9.9 upper limit for her age. With her symptoms, that fits PCOS, and a doctor would check androgens and rule out other causes before diagnosing it.
Which test to use
| If you want | Test | Where |
|---|---|---|
| Your ovarian reserve before egg freezing or IVF | AMH, often with an antral follicle count | Fertility clinic or lab (not SiPhox) |
| A reproductive hormone snapshot | FSH, LH, estradiol, progesterone, prolactin, testosterone | SiPhox Hormone Focus |
| Hormones plus heart and metabolic markers | FSH, LH, estradiol with ApoB, HbA1c, vitamin D | SiPhox Longevity Essentials |
| Checking for PCOS | Free androgen index, LH:FSH ratio, DHEA-S, HbA1c; AMH from a lab | SiPhox Hormone Focus plus your doctor |
Does SiPhox test AMH?
No. AMH is not on any of SiPhox's six EasyDraw panels. SiPhox lists a Wellness & Fertility+ add-on only for its older finger-prick kits, not EasyDraw, and we could not confirm which markers it includes. If AMH is the number you need, get it from a lab or fertility clinic.
What SiPhox does measure for reproductive health is FSH, LH and the LH:FSH ratio, found on Longevity Essentials, Hormone Focus and Ultimate 360. Hormone Focus adds progesterone, prolactin and the free androgen index. FSH is the traditional early-cycle ovarian reserve marker, though the ASRM notes it varies from cycle to cycle, so a single value is less reliable than AMH.
| SiPhox panel | Biomarkers per test | Per test, with shipping | Listed as |
|---|---|---|---|
| Longevity Essentials | 31 | $149 | FSH (women) (Hormones) |
| Hormone Focus | 14 | $149 | FSH (Hormones) |
| Ultimate 360 | 62 | $274 | FSH (Hormones) |
SiPhox is a wellness service with no doctor review included. See our perimenopause blood test guide and at-home hormone test for women.
A note on home samples: SiPhox's partner lab tests capillary blood collected from the upper arm. SiPhox says its results show a 95% to 99% correlation with venous draws in its own quarterly comparisons against Labcorp and Quest, but it has not published a study of the EasyDraw device. If a result would change a treatment decision, confirm it with a venous test through your doctor.

Frequently asked questions
What is a normal AMH level by age?
At Mayo Clinic Laboratories: 1.2 to 12 ng/mL at 20 to 24, 0.89 to 9.9 at 25 to 29, 0.58 to 8.1 at 30 to 34, 0.15 to 7.5 at 35 to 39, 0.03 to 5.5 at 40 to 44 and under 2.6 at 45 to 50.
Does low AMH mean I cannot get pregnant?
No. The ASRM says AMH is a poor predictor of natural fertility independent of age, and a large study found AMH under 0.7 ng/mL did not lower pregnancy rates over 12 cycles. It does predict egg yield in IVF.
Is high AMH a sign of PCOS?
It can be. The 2023 PCOS guideline allows AMH in adults as an alternative to ultrasound, but AMH alone cannot diagnose PCOS.
How do I convert AMH from ng/mL to pmol/L?
Multiply by 7.14. For example, 2 ng/mL is about 14.3 pmol/L.
Does SiPhox test AMH?
No. AMH is not on SiPhox EasyDraw panels. SiPhox covers FSH, LH, estradiol, progesterone and prolactin instead.
