Low AMH? What Your AMH Result Really Tells You About Your Fertility

If you’ve recently had fertility blood tests and been told that your AMH is low, it can feel incredibly worrying.

For many women, the first thing they do is Google it — and within minutes they’re reading about “diminished ovarian reserve”, IVF response and declining fertility.

But AMH is only one piece of the fertility picture.

A low AMH result does not tell you that you cannot get pregnant. It doesn’t tell us the quality of your eggs, and it certainly shouldn’t be looked at in isolation.

So, what does your AMH result actually tell you?

 

 

 

What is AMH?

AMH stands for Anti-Müllerian Hormone.

It is produced by the small developing follicles within your ovaries and is commonly used as a marker of ovarian reserve — essentially, an indication of the remaining pool of follicles in the ovaries.

Unlike some other reproductive hormones, AMH can usually be measured at any point during the menstrual cycle because levels tend to fluctuate less throughout the month.

However, AMH naturally changes with age and can also be influenced by factors including hormonal contraception and certain medical conditions.

Does low AMH mean I have poor-quality eggs?

This is one of the biggest misconceptions we hear.

AMH is much more closely related to egg quantity than egg quality.

Egg quality is strongly associated with age, although many different factors contribute to reproductive health.

This means two women of the same age could have very different AMH results without that result alone telling us which woman is more likely to conceive naturally.

That’s why we never want someone to look at an AMH number and feel that it represents their entire fertility.

It doesn’t.

Can I get pregnant naturally with low AMH?

Yes. Women with low AMH can and do conceive naturally.

AMH is particularly useful within fertility treatment because it can help fertility clinics estimate how the ovaries may respond to stimulation medication during IVF.

Someone with a lower AMH may produce fewer follicles during stimulation than someone with a higher ovarian reserve.

But trying to predict natural conception from AMH alone is much more complicated.

For natural conception, we also need to consider:

• your age
• whether you are ovulating
• sperm health
• fallopian tube health
• timing of intercourse
• endometriosis or other gynaecological conditions
• thyroid and general health
• the uterine environment
• how long you have been trying to conceive

This is why fertility should always be viewed as a whole picture rather than a single blood result.

What is considered a normal AMH?

This is where Google can cause even more confusion.

AMH is commonly reported in the UK in pmol/L, but laboratories and fertility clinics can use different reference ranges and testing methods.

Your age matters enormously when interpreting the result.

AMH naturally declines as we get older, so comparing your AMH with that of someone ten years younger isn’t particularly useful.

Your fertility clinic may also perform an antral follicle count (AFC) during an ultrasound scan. This looks at the number of small follicles visible within the ovaries.

Looking at AMH alongside your AFC, age, menstrual history and other fertility investigations gives a much more useful picture than AMH alone.

What about high AMH?

Higher isn’t necessarily better.

A higher AMH can indicate a larger ovarian reserve, but particularly high levels are also commonly seen in women with polycystic ovary syndrome (PCOS).

Women with PCOS can have a larger number of small follicles within their ovaries, which can result in higher AMH levels.

During IVF, people with a high ovarian reserve may also respond strongly to stimulation medication. Fertility clinics therefore consider AMH when deciding how treatment should be managed.

Again, the number needs context.

AMH and IVF

AMH becomes particularly useful when you’re preparing for IVF.

Your fertility clinic may use your AMH result alongside your ultrasound scan, age and other information to help determine:

• which stimulation protocol may be appropriate
• the starting dose of medication
• how strongly your ovaries may respond
• whether you may have a reduced response to stimulation
• whether you may be at greater risk of an excessive response

A low AMH may mean fewer eggs are collected during an IVF cycle.

But number of eggs and quality of eggs are not the same thing.

Ultimately, IVF isn’t simply about producing the largest possible number of eggs. The aim is to obtain eggs capable of fertilising and developing into healthy embryos.

Can you increase your AMH?

This is another question we hear frequently.

There isn’t currently a proven supplement, food, acupuncture treatment or lifestyle programme that can reliably replenish your ovarian reserve.

And we think it’s important to be honest about that.

You may see supplements or programmes online promising to dramatically increase AMH or “reverse ovarian ageing”. Be cautious about these claims.

Instead, when we work with someone with a lower ovarian reserve, our focus is on the areas we can potentially influence.

Depending on the individual, this might include nutrition, lifestyle, sleep, stress management, correcting nutritional deficiencies where appropriate, stopping smoking, moderating alcohol and making sure relevant medical conditions have been properly investigated.

The aim isn’t to magically create more eggs.

It’s about supporting your overall health and reproductive wellbeing while you decide on your next steps.

What should I do if I’ve just been told my AMH is low?

First, don’t panic based on one number.

Ask what your AMH means for your age and your individual circumstances.

Depending on your situation, it may also be appropriate to look at your antral follicle count and other fertility investigations.

And don’t forget the other half of the fertility equation.

If you’re trying to conceive with a male partner, a semen analysis — and in some circumstances further sperm investigations — can be just as important as investigating female fertility.

If you’ve been trying for some time, particularly if you’re over 35, seeking professional fertility advice sooner rather than later can also be sensible.

How we support fertility at The Natural Fertility Clinic

At The Natural Fertility Clinic, we regularly meet women and couples who arrive feeling completely overwhelmed by blood results, fertility terminology and conflicting information online.

Our approach is to look at the whole fertility picture.

Depending on your individual circumstances, support may include fertility acupuncture, IVF acupuncture, fertility-focused nutrition and lifestyle support, fertility massage, reflexology and fertility consultations.

We work alongside conventional fertility treatment and don’t see complementary support as a replacement for appropriate medical investigations or treatment.

We support patients from our clinics in Wokingham, Abingdon and Maidenhead, including patients undergoing IVF and other assisted fertility treatments.

Your AMH is a piece of information — not a verdict

Perhaps the most important thing to take away from this article is this:

Your AMH result is not your fertility score.

It gives us useful information about ovarian reserve and can be particularly helpful when planning fertility treatment.

But it cannot, on its own, tell you whether you will or won’t become pregnant.

Fertility is rarely about one hormone, one test or one number.

It’s about putting all of the pieces together.

Frequently Asked Questions About AMH

Can I get pregnant naturally with low AMH?

Yes. A low AMH does not mean natural pregnancy is impossible. AMH provides information about ovarian reserve but is not, on its own, a reliable prediction of whether an individual woman will conceive naturally.

Your age, ovulation, fallopian tubes, sperm health and other fertility factors all need to be considered.

What is a good AMH level for my age?

There isn’t one AMH number that is “good” for everyone.

AMH naturally declines with age, and laboratories can use different assays and reference ranges. Your result should therefore be interpreted in the context of your age, medical history, antral follicle count and other fertility investigations rather than compared with a single number found online.

What does an AMH below 5 pmol/L mean?

An AMH below 5 pmol/L would generally be considered on the lower side by many fertility clinics, but the significance depends on your age, the laboratory’s reference range and the rest of your fertility picture.

In IVF, a lower AMH may suggest that fewer follicles could respond to stimulation.

It does not mean that you have no eggs or that you cannot become pregnant.

Always discuss the actual result with your fertility specialist rather than interpreting the number in isolation.

Does low AMH mean poor egg quality?

No. AMH is primarily a marker of egg quantity or ovarian reserve, not egg quality.

Age is one of the strongest factors associated with egg quality, which is why your age needs to be considered alongside AMH.

Can AMH levels increase?

AMH results can fluctuate, and different laboratories or testing methods may produce slightly different results.

However, there is currently no proven treatment, supplement or lifestyle change that reliably restores the ovarian reserve or permanently increases the number of eggs remaining in the ovaries.

Be cautious of products or programmes promising to dramatically “boost” AMH.

Does low AMH mean I’m going through early menopause?

Not necessarily.

A low AMH can indicate a lower ovarian reserve, but AMH alone cannot tell you exactly when you will reach menopause.

If you have irregular or absent periods, menopausal symptoms or concerns about premature ovarian insufficiency (POI), speak to your GP or fertility specialist so that appropriate investigations can be arranged.

Which is more important — AMH or antral follicle count?

Neither test tells the whole story.

AMH is measured through a blood test, while an antral follicle count (AFC) is performed using ultrasound to count the small follicles visible in the ovaries.

Fertility specialists often consider the two together, alongside age and other investigations, particularly when planning IVF treatment.

Feeling confused by your fertility results?

If you’ve had fertility blood tests or investigations and have been left wondering “What does all of this actually mean?”, you don’t have to try to piece everything together from Google.
