AMH test

A fertility test to determine how many eggs you have left

Ovarian reserve refers to the number and quality of your remaining eggs. One of the most reliable indicators of ovarian reserve is the anti-Müllerian hormone (AMH) test.

At Demeter Fertility, we provide AMH testing as part of a comprehensive fertility assessment, helping you understand how your ovarian reserve compares to expected AMH levels by age in Australia.

What is ovarian reserve?

At birth, a baby girl has around 2 million immature eggs (oocytes). By puberty, this number has decreased to 300,000-400,000. By age 37, most women only have about 25,000 eggs left. By age 51 (average age of menopause), the average is down to just 1,000.

As you can see, ovarian reserve naturally declines with age, particularly after the mid-30s. It can also be affected by factors such as:

Genetics
Certain medical conditions (e.g. endometriosis, autoimmune disorders)
Previous ovarian surgery
Cancer treatments such as chemotherapy or radiotherapy.

What is AMH testing?

If you’re struggling to conceive, it’s important to know how many remaining eggs you have. This is a key measure of reproductive potential and can influence the chances of natural conception or success with fertility treatment.

AMH stands for anti-Müllerian hormone – a hormone produced by small follicles in your ovaries. Your AMH level reflects your ovarian reserve, which is the number of eggs remaining in your ovaries.

High AMH levels may indicate a higher ovarian reserve. Low AMH levels may suggest a diminished ovarian reserve, meaning there are fewer eggs available.

It’s important to note that AMH levels do not measure egg quality – only quantity. A high AMH level does not guarantee your ability to conceive. However, it’s certainly very useful information that can inform treatment decisions.

How to test for low AMH

An AMH test is a blood test that can be taken at any point in your menstrual cycle. At Demeter Fertility, your AMH level is interpreted alongside your medical and reproductive history and the results of other fertility tests, such as:

This comprehensive approach ensures that your AMH result is considered in the context of your overall fertility health.

Can you get pregnant with low AMH?

Yes – many women with low AMH still become pregnant naturally or with fertility treatment. While low ovarian reserve can mean fewer eggs are available, conception depends on multiple factors, including egg quality, sperm health, uterine health, and overall reproductive function.

At Demeter Fertility, we’ve seen low AMH success stories, using personalised treatment plans to improve the chances of pregnancy.

Can I increase my AMH level?

There is currently no scientifically proven way to permanently increase AMH levels.

How can I support my fertility with low AHM?

There are lifestyle changes that may support your overall fertility, such as:

Maintaining a healthy weight
Eating a balanced, nutrient-rich diet
Avoiding smoking and excessive alcohol
Managing underlying health conditions.

At Demeter Fertility, we also offer targeted medical treatments. These will not directly raise AMH levels but they may support your overall fertility.
