AMH, Ovarian Reserve & Egg Quality: What They Really Mean for Fertility

If you’ve recently been told that your AMH is low, it’s very easy for that one number to take on far more meaning than it should.

I often speak to women who’ve come away from an AMH result worrying that they’re “running out of eggs”, that their eggs must be poor quality, or that their chances of becoming pregnant are suddenly very low.

AMH can give us useful information, particularly when planning fertility treatment. But it’s only one part of a much bigger picture.

And importantly, AMH, ovarian reserve and egg quality aren’t the same thing.

Understanding that difference can make an AMH result feel much less like a verdict and much more like what it actually is: one piece of information that needs to be understood in context.

What exactly is AMH?

AMH stands for anti Müllerian hormone. It’s produced by cells surrounding the small developing follicles within the ovaries.

Because the level of AMH broadly reflects the number of these follicles, a blood test can help give an indication of your ovarian reserve.

Ovarian reserve refers to the remaining pool of eggs within the ovaries. We can’t simply count how many eggs someone has left, so AMH and an ultrasound measurement called the antral follicle count, or AFC, are used as indirect markers.

AMH is therefore useful, but the important word here is quantity.

It doesn’t directly measure the quality of the eggs within that pool. ASRM

Ovarian reserve and egg quality are different things

This is probably the most important distinction to understand.

Very simply:

Ovarian reserve tells us broadly about egg quantity.

Egg quality refers more to an egg’s reproductive potential, including its ability to fertilise, develop into a healthy embryo and ultimately contribute to a pregnancy.

You may sometimes hear doctors talk about whether an egg or embryo is chromosomally normal or abnormal. Chromosomes are the structures inside our cells that carry our genetic information. An egg with the expected number of chromosomes has a better chance of developing normally, while an egg with too many or too few chromosomes is less likely to result in an ongoing healthy pregnancy.

AMH can’t tell us whether an individual egg has the expected number of chromosomes. It also can’t tell us whether a particular egg will fertilise or whether an embryo will implant.

That’s why someone can have a relatively low AMH and still produce a healthy egg, while someone with a high AMH doesn’t automatically have better quality eggs.

So what does a low AMH actually mean?

A lower AMH usually suggests a smaller follicular pool than might be expected.

That information becomes particularly useful if you’re having in vitro fertilisation, or IVF, because it can help your fertility specialist estimate how your ovaries may respond to stimulation and roughly how many follicles, and therefore potentially eggs, might be recruited. Acupuncture is often used alongside IVF support during this process.

But a low AMH result doesn’t automatically mean that you can’t conceive naturally, and it shouldn’t be used as a simple measure of whether somebody is fertile or infertile.

This distinction is now particularly clear in the updated National Institute for Health and Care Excellence, or NICE, 2026 fertility guidance.

NICE specifically recommends that AMH shouldn’t be used to predict the chance of pregnancy through natural conception. Instead, AMH or antral follicle count can be used to help predict how the ovaries may respond and to support planning and counselling in assisted conception.

That’s quite an important difference.

An AMH test is much better at helping answer:

“How might my ovaries respond if we stimulate them?”

than:

“Can I become pregnant?”

Research also suggests that even very low AMH shouldn’t, on its own, be used to decide that IVF treatment is futile. There isn’t a single AMH level below which live birth becomes impossible. ASRM

And what about a high AMH?

Higher AMH generally suggests a larger number of follicles and can sometimes mean a stronger response to ovarian stimulation medication.

It’s also commonly seen in women’s health conditions such as polycystic ovary syndrome, or PCOS, increasingly also referred to as polycystic ovary morphology syndrome, or PMOS, where there may be a larger number of small follicles within the ovaries.

But more isn’t automatically better.

A higher AMH doesn’t guarantee easier natural conception, better quality eggs or a successful pregnancy. In fertility treatment, a very strong ovarian response may actually mean medication needs to be managed carefully to reduce the risk of the ovaries responding too strongly. NICE

So whether AMH is relatively low or high, the number still needs to be understood alongside everything else.

Why age still matters

AMH and age tell us different things.

AMH gives us information mainly about ovarian reserve. Age is more closely linked with changes in egg quality, including the likelihood that an egg has the expected number of chromosomes.

As we get older, a greater proportion of eggs may carry an incorrect number of chromosomes. This can make fertilisation, embryo development and ongoing pregnancy less likely.

That doesn’t mean every egg becomes “poor quality” after a particular birthday. Fertility doesn’t work in neat cut off points.

It does mean that age remains an important part of fertility assessment, alongside ovarian reserve and the wider reproductive picture.

Fertility is much bigger than one blood result

It’s tempting to focus on AMH because it gives us a number. Numbers feel concrete.

But becoming pregnant depends on far more than ovarian reserve, including:

  • your age and menstrual cycle pattern;
  • whether you’re ovulating regularly;
  • sperm health;
  • whether the fallopian tubes are open and functioning;
  • the health of the uterus and its lining;
  • conditions such as endometriosis, adenomyosis or PCOS or PMOS;
  • previous pregnancies or fertility treatment;
  • and your general health and wellbeing.

That’s why AMH is best looked at as one part of the fertility picture rather than as a result that stands alone.

Can AMH or egg quality change?

This is where the conversation becomes more nuanced.

AMH isn’t completely fixed. Levels can fluctuate, and factors including hormonal contraception and differences between tests or laboratories can affect results. ASRM

In clinical practice, we also sometimes see AMH measurements change over time when patients have made broader changes to their health, nutrition and lifestyle or have been receiving acupuncture, which may also support restoring hormonal balance. Those observations are interesting, and research is continuing to explore whether acupuncture may influence ovarian reserve markers and ovarian function.

For example, a systematic review of randomised trials in women with diminished ovarian reserve reported changes in markers including AMH and antral follicle count following acupuncture, although the authors also highlighted limitations in the available studies.

More recent research in women with diminished ovarian reserve undergoing IVF or intracytoplasmic sperm injection, known as ICSI, has also reported potentially encouraging findings across several outcomes, including the number of eggs retrieved, implantation, pregnancy and live birth. However, the strength of the evidence varied across these outcomes, so larger and more rigorous studies are still needed. PubMed

It’s important, though, to be clear about what each piece of research is actually measuring.

A change in AMH isn’t automatically the same thing as a change in egg quality. More eggs retrieved doesn’t necessarily mean more healthy embryos, and pregnancy rates and live birth rates are different outcomes again.

That doesn’t make these findings unimportant. It simply means we need to interpret them carefully.

Where might acupuncture fit?

When I work with fertility patients, I’m rarely looking at AMH in isolation.

Acupuncture may form part of a broader approach to reproductive health, whether somebody is trying to conceive naturally, preparing for fertility treatment or already going through an IVF cycle. Our acupuncture treatments are tailored to each individual’s cycle and health history.

Depending on the individual, treatment may focus on menstrual and ovulatory patterns, symptoms associated with underlying conditions, general wellbeing and the physical and emotional demands of fertility treatment.

Research into acupuncture and diminished ovarian reserve is developing, and there are some encouraging signals around ovarian reserve markers, ovarian response and fertility treatment outcomes. At the same time, the evidence isn’t yet strong enough to tell us with certainty which women are most likely to benefit, which outcomes may be affected or how large those effects might be. PubMed

For me, that means neither overpromising nor dismissing what we’re seeing.

It means looking at the whole person, working alongside appropriate fertility investigations and treatment, and keeping the evidence and its uncertainties in perspective.

A few common questions

Does low AMH mean I have poor quality eggs?

No. AMH is mainly a marker of ovarian reserve, so it gives information about egg quantity rather than directly measuring egg quality.

Age is more closely associated with changes in egg quality, but even age can’t tell us the quality of an individual egg.

Can I still conceive naturally with low AMH?

Yes, natural conception is still possible with a low AMH.

AMH isn’t recommended as a test for predicting whether someone will conceive naturally. Other factors such as age, ovulation, sperm health, fallopian tube function and underlying reproductive conditions also matter.

Does high AMH mean I’m very fertile?

Not necessarily.

A high AMH usually suggests a larger number of follicles, but it doesn’t tell us whether those eggs are good quality or whether pregnancy will happen easily.

Can AMH go up as well as down?

AMH levels can vary between tests, and certain factors can affect the result.

Changes are sometimes also seen over time in clinical practice, including in patients who’ve made dietary and lifestyle changes or who are receiving acupuncture. At present, research can’t tell us with certainty what causes those changes or whether a change in the AMH number always reflects a meaningful change in fertility.

Why do fertility clinics test AMH if it doesn’t predict whether I’ll get pregnant?

Because AMH is very useful for a different reason.

It helps fertility specialists estimate how the ovaries may respond to stimulation medication during treatments such as IVF. That can help with planning treatment and discussing what kind of ovarian response might reasonably be expected.

One number shouldn’t become a verdict

If there’s one thing I’d like you to take from this article, it’s this:

AMH is useful information, but it isn’t a fertility score.

A low result doesn’t tell you that your eggs are poor quality. A high result doesn’t guarantee good quality eggs. And neither result, on its own, can tell you whether you’ll conceive naturally.

If your AMH has caused you concern, the most useful next step is usually to look at it alongside your age, cycle history, antral follicle count where appropriate, sperm factors and any other relevant investigations.

That gives you a much more meaningful picture than one number ever could. At The Acupuncturists Ltd, we’re happy to talk through how acupuncture might support your wider fertility picture — get in touch to find out more.
