Your AMH level is the best blood clue to your egg supply. It is one number that says a lot about where you stand. But it is also easy to misread. AMH predicts how you respond to fertility treatment well. It does not perfectly predict natural pregnancy.
This guide covers what AMH is, what your number means, and how to use it.
AMH comes from small, growing follicles in your ovaries. It tracks with your remaining egg count. Levels fall as you age. A low AMH suggests fewer eggs left. A high AMH often points to PCOS. AMH predicts fertility treatment success well, but many women with low AMH still get pregnant on their own.
AMH stands for anti-Müllerian hormone. It comes from cells inside your small, early-stage follicles. Your blood AMH level tracks with how many of these small follicles you have. That, in turn, tracks with your total egg supply.
A few key facts:
Age | Typical AMH (ng/mL) |
|---|---|
25 | 2.0 to 6.8 |
30 | 1.5 to 4.5 |
35 | 0.7 to 3.6 |
40 | 0.4 to 2.8 |
45 | 0.1 to 1.0 |
After menopause | Under 0.1 |
Always read your AMH against your own age group. A level of 1.5 ng/mL sits mid-range for a 32-year-old. For a 22-year-old, the same number is low.
This often points to PCOS, since PCOS ovaries hold more small follicles than typical. It can also mean a strong egg supply. In fertility treatment, a high AMH can raise the risk of a condition called OHSS, so your doctor will watch closely.
This usually means good egg supply. It is a good sign for both natural pregnancy and fertility treatment.
This means a modest supply. Natural pregnancy is still likely. Your response to fertility treatment may be a bit lower.
This points to fewer eggs than typical for your age. Fertility treatment may work less well. Your fertility window may be shorter than expected.
This is a bigger signal. It often means menopause is coming sooner than expected. Talk to a fertility doctor and think about your timeline soon.
Many women with low AMH still conceive on their own. Many women with normal AMH still struggle. AMH tracks egg count, not egg quality, and quality matters just as much.
AMH links to your eventual menopause age, but the link is loose at the individual level.
A low AMH alone is not proof of a fertility problem. A full check-up looks at other hormones, your cycle, and your health history too.
Things that lower it:
Things that may raise it:
Things that barely move it:
Your AMH sits within the typical range for your age. Keep your current plans. Check in again if pregnancy does not happen after a reasonable stretch of trying.
AMH is over 4.0 ng/mL, often with high testosterone or irregular cycles. This points to PCOS. Care usually focuses on restoring regular ovulation.
Your AMH sits below the typical range for your age, but your cycles and other hormones look fine. This is worth a chat with a fertility doctor about your timeline.
Both point to a smaller egg supply. This pattern often shows up near perimenopause. A fertility doctor can walk you through options like egg freezing.
Doctors track AMH after chemo or ovarian surgery to see how much the treatment affected your egg supply. This needs guidance from your treating doctor.
Curious how AMH fits into your full fertility picture? Our guide to fertility blood tests for women covers the full panel, including FSH, LH, and progesterone.
A baseline AMH in your late 20s gives you a marker for later. A low result at a young age is worth an early chat with a doctor. It can help guide choices about timing or egg freezing.
AMH, paired with day-3 FSH, LH, and estradiol, gives a fuller reserve picture. It also helps predict how you might respond to fertility treatment. Your thyroid belongs in that picture too, and TSH can affect your ability to conceive.
AMH is one of the strongest predictors of how many eggs a cycle might collect. A higher AMH often means more eggs per cycle.
Long-term use can lower AMH slightly. For the clearest reading, test 3 months after stopping.
AMH needs a simple blood draw, any day of your cycle. No fasting is needed.

This is one of the most common questions, and the honest answer is: not by much.
AMH mostly reflects your set egg supply, which falls with age and does not shift much with lifestyle. A few things may help at the edges:
For most healthy women, AMH cannot be meaningfully raised. It works better to plan around your current number than to try to change it.
There is no single "good" number. It depends on your age. Sitting within your age-typical range, with regular cycles, is a reassuring sign.
For general fertility planning, every 1 to 2 years works well until you make decisions or reach perimenopause. Your doctor may want more frequent checks after treatment or with a low result.
No. A low AMH for your age suggests earlier menopause is more likely, but it cannot give you an exact date.
Yes. Many women with low AMH conceive naturally. AMH reflects egg count, and quality matters too but is harder to measure directly. A low AMH may mean a shorter window, not an impossible one.
No, not for fertility. Men make AMH mainly early in life. Adult male fertility testing focuses on a sperm test, testosterone, FSH, and LH instead.
