AMH levels, what does it all mean?

AMH Levels

Common questions about Anti-Mullerian Hormone 

As a woman, it’s likely that you’re very familiar with the routine of having your period. 

But what you may not know is the mechanics of your cycle and how it is affected and changes with time. 

It may not be the most pleasant subject in the world. 

But knowing the basics of what drives the ovulation process can help you in your efforts to conceive. 

One of the indicators of a women’s fertility is a reproductive hormone called Anti-Mullerian Hormone. 

This is a hormone that occurs in both males and females. 

Here are common questions about Anti-Mullerian Hormone in women.

What is Anti-Mullerian Hormone? 

You can think of Anti-Mullerian Hormone as an indicator of your egg supply. 

Anti-Mullerian Hormone is a regulatory substance released from the follicles (egg sacs) inside the ovaries. 

The release of AMH is mainly a response to how many follicles are moving towards maturation. 

  • High levels of AMH indicate there are lots of follicles in the ovarian reserve 

  • Low levels of AMH indicate there are fewer follicles in the ovarian reserve 

High AMH levels prevent over supply of eggs when there is a lot of activity. 

Low AMH levels allow the low supply of eggs to mature when there is less activity. 

What are normal AMH levels? 

Normal AMH levels vary depending on a woman’s age. 

AMH levels are usually measured by nanograms per millilitre. 

When a woman is fertile, her AMH levels are between 1.0 ng/ml and 4.0 ng/ml. 

An AMH level below 1.0 ng/ml indicates there is reduced ovary activity and further fertility investigation may be needed. 

Where can I get an AMH test done? 

An AMH test sounds like some kind of fancy test, but it’s actually a regular blood test. 

Your GP or fertility specialist can order an AMH blood test at your request. 

You can get this blood test done at a pathology clinic, which you’ll find at your GP or fertility clinic. 

Blood test to check ovarian reserve? 

An AMH blood test usually provides your AMH levels in the form of a certain number of nanograms per millilitres. 

This result can help your doctor predict the number of eggs left in your ovarian reserve. 

This may give you an indication of when you’ll reach menopause. 

When to test AMH levels? 

There’s no “right” time during the ovulation cycle to test your AMH levels. 

You can have your AMH levels tested on any day during your cycle. 

Can AMH levels fluctuate? 

AMH levels don’t fluctuate very much. 

This is why you can have an AMH blood test at any stage during your cycle. 

Can I increase my AMH levels? 

AMH levels naturally decrease with age. 

If you’re in the reproductive age bracket, you can increase your AMH levels. 

There are plenty of ways you can increase your AMH levels. 

From a broad perspective, you can increase your AMH levels by improving your overall health. 

Some of the ways that you can help increase your AMH levels include: 

  • Balanced diet 
  • Exercise 

  • Vitamin D (consult your doctor) 
  • Fish oil (consult your doctor) 
  • Quit smoking 
  • Decrease alcohol intake 
  • Acupuncture 

Can low AMH levels cause miscarriage? 

There have been studies that have tracked the AMH levels of women who have had a miscarriage. 

A study by Dr. Brianna Lyttle Schumacher of UNC showed that women with AMH levels less than 1.0 ng/ml had 2.2 times more risk of miscarriage. 

However, the study also showed that women with the highest AMH levels were more likely to miscarriage earlier. 

If I have low AMH can I get pregnant naturally? 

The short answer is, yes. 

Just because you have low AMH levels, doesn’t necessarily mean you can’t conceive a baby naturally. 

There have been cases where women have successfully fallen pregnant, even when their AMH levels have been low. 

Can IVF work with low AMH? 

Yes, IVF can work with low AMH levels. 

Your IVF specialist will determine the amount of stimulation to give your eggs based on your AMH levels. 

If your AMH levels are low, your eggs will need more stimulation. 

What AMH level indicate menopause? 

A female is born with around 1,000,000 follicles (egg sacs) in her ovaries. 

When she reaches puberty this number falls to around 400,000. 

The ovaries absorb the remaining follicles during childhood. 

Only 300 to 500 eggs will be released in total during a woman’s reproductive years. 

The rest will be absorbed by the ovaries. 

The three stages of menopause generally occur from the mid-40s to late-50s. 

Although the process can begin sooner. 

The initial perimenopause stage that leads up to menopause can last anywhere from 4 to 10 years. 

If you get an AMH test, it can help predict when you’re likely to reach menopause. 


Are you trying to conceive a baby? 

If so, it’s a good idea to get your AMH levels tested. 

The results of your AMH test can give you a better idea of your fertility levels. 

Your AMH levels can help your doctor provide you with further advice and treatment. 

If you’re in your mid to late 30s, it’s important to address your AMH levels sooner rather than later. 

A low AMH level will continue to decrease without the correct treatment. 

Talking to your health care provider or doctor about your AMH levels can also help them to rule out other issues and conditions that could be affecting your fertility. 

By addressing things sooner, it gives you a better chance of having a baby.
