Quick Answer: What is an AMH test?
An anti-Müllerian hormone (AMH) test is a blood test that measures AMH, a hormone made by the follicles in the ovaries that reflects how many eggs you have left. An average level is 1.0 to 3.0 ng/mL, and below 1.0 ng/mL is low. AMH does not predict whether you can get pregnant or when menopause will start. [1]
What the research says
A low AMH did not lower the chance of natural pregnancy. In 750 women aged 30 to 44 trying to conceive without known infertility, those with low AMH (below 0.7 ng/mL) were as likely to conceive within 6 cycles (65%) as those with normal AMH (62%), and within 12 cycles (84% vs 75%). (Steiner et al., JAMA, 2017) [2]
AMH helps but cannot diagnose PCOS on its own. A meta-analysis of 82 studies for the 2023 international PCOS guideline found AMH identified PCOS in adults with 79% sensitivity and 87% specificity, but concluded AMH alone is not enough to diagnose PCOS and no single cut-off could be recommended. (van der Ham et al., Fertility and Sterility, 2024) [3]
Key takeaways
AMH is made by the follicles in the ovaries and roughly reflects how many eggs remain. [1]
Levels rise in the teen years, peak around age 25 and then decline. [1]
An average level is 1.0 to 3.0 ng/mL; below 1.0 ng/mL is low. [1]
The test can be done any day of your cycle and needs no preparation. [1]
AMH does not predict your fertility or when menopause will happen. [1]
What is anti-Müllerian hormone (AMH)?
Everyone makes AMH, but providers mainly test it in women. Before birth, AMH helps the sex organs develop: male fetuses have higher levels, which stops female reproductive organs from forming, while female fetuses need only a small amount. [1]
In females, AMH is made by cells in the ovarian follicles, the fluid-filled sacs that hold and release eggs. AMH levels track with ovarian reserve: higher levels suggest more eggs, and lower levels suggest fewer. [1]
Why is an AMH test done?
To estimate ovarian reserve. It gives a sense of how many eggs remain and whether your ovaries may be aging faster than expected, which may suggest a shorter window for pregnancy. [1]
Before IVF. It may show how well you will respond to injectable fertility medicines that help several eggs mature. [1]
To check an ovarian tumor. It can help show whether an ovarian mass is a granulosa cell tumor, whether treatment is working and whether the tumor has come back. [1]
How do you prepare for an AMH test?
No preparation is needed. Unlike other reproductive hormones, AMH changes little during the month, so the test can be done on any day of your menstrual cycle. [1]
What happens during an AMH test?
It is a simple blood draw. A provider uses a thin needle to take blood from a vein in your arm, which takes just a few minutes. If the sample goes to a lab, results may take a few days. Your provider usually schedules a follow-up to go over your results and plan next steps. [1]
What are normal AMH levels?
AMH is measured in nanograms per milliliter (ng/mL). Experts still debate the exact normal ranges, and results can vary slightly between labs because they use different equipment. [1]
AMH level | What it suggests |
1.0 to 3.0 ng/mL | Average |
Below 1.0 ng/mL | Low |
0.4 ng/mL | Severely low |

AMH levels by age
AMH rises during the teen years, peaks around age 25 and then naturally declines. Lower-end estimates by age are: [1]
Age | Lower-end AMH level |
25 | 3.0 ng/mL |
30 | 2.5 ng/mL |
35 | 1.5 ng/mL |
40 | 1.0 ng/mL |
45 | 0.5 ng/mL |

What do high and low AMH results mean?
A low AMH suggests a lower egg supply and may mean a shorter window for pregnancy. [1]
A higher AMH is not always better. AMH can be high in some people with polycystic ovary syndrome (PCOS), and the 2023 international PCOS guideline now uses AMH to help define polycystic ovaries in adults. [1] [3]
What can't an AMH test tell you?
AMH does not predict your fertility, with or without treatment, and it does not predict when menopause will happen. [1]
Many other factors affect your chance of getting pregnant even when AMH is typical, including: [1]
Age
Medical conditions
Smoking
Sperm count and motility
Ovulation problems
Blocked fallopian tubes or pelvic scarring
Endometriosis
Uterine problems such as fibroids
Are at-home AMH tests reliable?
At-home AMH tests, usually done with a finger prick, are sold in stores and online. Because fertility needs a full evaluation, it is best to have a specialist interpret your result. [1]
Conclusion
An AMH test is a simple blood test that estimates your remaining egg supply and helps plan fertility treatment such as IVF. Levels fall with age, and a low result may point to a shorter window for pregnancy.
AMH is only one piece of the picture. If you are trying to conceive or want to understand your reproductive health, see a specialist for a full fertility evaluation.
