What Is AMH? AMH Normal Range by Age

Updated 9/11/2026

Quick Answer

AMH (anti mullerian hormone) is a hormone made by tiny, early-stage eggs sitting inside your ovaries, called ovarian follicles. Doctors use an anti mullerian hormone test to guess how many eggs you have left. It's a simple AMH blood test, and you can take it on any day of your menstrual cycle, since the number stays pretty steady all month.

Here's a simple chart of AMH levels by age (numbers are in ng/mL, and reference ranges can vary slightly by lab):

Under 30 yrs: 2.0–6.8
30–35 yrs; 1.5–4.0
35–40 yrs: 1.0–3.0
40–45 yrs: 0.3–1.5
Over 45 yrs: Often below 0.5

AMH naturally goes up during your teenage years, is highest around age 25, and then slowly goes down as you get older. A lower number just means fewer eggs are left. It does not tell you whether you can get pregnant.

What Is AMH, Really?

AMH plays a small role early in life, before birth. Later on, in women, it's made by cells inside small follicles in the ovaries, these are the tiny sacs that hold your eggs.

Since the number of these small follicles roughly matches how many eggs are left, your AMH number gives a rough idea of your egg supply:

Higher AMH usually means more eggs remain
Lower AMH usually means fewer eggs remain

That's really all AMH tells you. It's about how many eggs you have, not how healthy they are.

Why Does Age Matter So Much?

You're born with every egg you'll ever have, somewhere around 1 to 2 million. By the time you hit puberty, that number has already dropped to around 300,000–400,000. From there, it keeps going down a little every single month, whether or not you get pregnant. By age 30, most women have about 12% of their original eggs left. By 40, it's closer to 3%.

This is exactly why AMH numbers look so different depending on your age:

In your 20s: AMH is usually at its highest.
Early to mid 30s: It starts slowly going down.
Late 30s: The drop becomes more noticeable.
40s: Levels are usually under 1.0 ng/ml, sometimes much lower.
Close to menopause: AMH often drops below 0.5 ng/ml.

Some research suggests women in India may see this drop happen a little earlier than in Western countries. So it's smart to compare your number to your own lab's reference ranges, not just a general chart.

What Counts as Low, Normal, or High?

Since labs use slightly different testing methods, exact numbers can shift a bit. But roughly:

Normal: About 1.0 ng/ml to 3.0 ng/ml, depending on age
Low: Below 1.0 ng/ml
Very low: Around 0.4 ng/ml or lower
High: Above 4.0 ng/ml, sometimes linked to polycystic ovary syndrome (PCOS)

A high AMH level isn't always something to celebrate. If your periods are irregular and your AMH is high, it could be a sign of PCOS rather than just great fertility. On the other end, doctors sometimes describe a low result as diminished ovarian reserve, meaning fewer eggs than expected for your age.

What Can (and Can't) AMH Tell You?

What it CAN tell you:

A rough idea of how many eggs remain
Whether your ovaries seem to be aging faster than usual
How well you might respond to fertility treatment, especially in vitro fertilization (IVF)

What it CANNOT tell you:

Whether you'll get pregnant naturally this month
When you'll go through early menopause
Anything about your egg quality, that depends mostly on age, not AMH

Even with a totally normal AMH, other things can still affect your chances of getting pregnant. This includes irregular ovulation, blocked tubes, endometriosis, uterine issues, or your partner's sperm health.

AMH vs. Other Ovarian Reserve Tests

AMH is one of a few common ovarian reserve tests. Here's how they compare:

AMH: How many eggs remain; useful for planning fertility treatment. It is done through blood test, any day of your cycle
FSH (Follicle-Stimulating Hormone): How hard your body is working to release an egg each month. It is done through blood test, usually early in your cycle
AFC (Antral Follicle Count): Number of small follicles seen on ultrasound. It is done through ultrasound scan, early in your cycle

AMH and AFC usually match each other closely and are the best combo for predicting how you'll respond to IVF. But none of these tests can promise whether you'll get pregnant naturally.

Can You Still Get Pregnant With Low AMH?

Yes, absolutely. This is probably the most misunderstood part of AMH. To get pregnant naturally, you only need one healthy egg each month. So even with fewer eggs left overall, your monthly chances aren't necessarily much lower.

Big studies have shown that women with low AMH, even below 1.0 ng/ml, don't have a much lower chance of getting pregnant naturally compared to women with a normal AMH, as long as they're ovulating regularly.

Low AMH matters more when it comes to IVF, since fewer eggs may be collected during treatment. So a low number is a good reason to talk to a fertility specialist soon. It's not a sign that pregnancy is out of reach.

What Causes Low AMH?

Age: By far, the biggest and most natural reason.
Family history: If your mother or sister had early menopause, you might too.
Endometriosis: Can directly affect the ovaries.
Past ovarian surgery: like removing a cyst.
Chemotherapy or radiation: Can lower egg supply.
Some autoimmune or genetic conditions
Smoking: Linked to fewer eggs and earlier menopause.

Can You Raise Your AMH?

Not really, no matter what some ads promise. You're born with all the eggs you'll ever have. No diet, pill, or lifestyle change can create new ones or truly raise your egg count. What you can do is take care of the eggs you have. Don't smoke, keep a healthy weight, eat well, manage stress, and treat any health issues like thyroid problems. Some supplements are talked about in fertility circles, but there isn't strong proof they work, so always check with a doctor first.

When Should You Get an AMH Test?

It's worth getting an AMH test if:

You're planning a pregnancy and want to understand your egg supply
You're under 35 and have been trying for over a year, or 35 and older and trying for over 6 months
You're thinking about freezing your eggs or delaying pregnancy
You have irregular periods, a family history of early menopause, or past ovarian surgery
You're starting IVF, since AMH helps your doctor build your treatment plan and weigh your treatment options

Frequently Asked Questions

There's no single "good" number for everyone, it depends on your age group. A 3.0 ng/ml result is great in your 20s but unusually high in your 40s. Always check your number against your own age range.

AMH gives you a helpful snapshot of how many eggs you have left, and it's especially useful for planning fertility treatment like IVF. But it was never meant to answer the question most people really want answered: "Will I get pregnant?" That depends much more on your age, regular ovulation, and overall health than on this one number. If your AMH comes back lower than expected, treat it as a nudge to talk to a fertility specialist, not as bad news about your future.
