What is
AMH?

Anti-Müllerian hormone (AMH) is made in your ovaries — specifically by the small follicles where your eggs develop. The number of follicles you have declines naturally with age. As AMH is only produced by ovarian follicles, the same decline is seen in the AMH level, which makes it a good indicator of your ovarian reserve.

What can I learn
from this test?

Our AMH Blood Test will tell you if your AMH level is normal for your age. If you’re undergoing in vitro fertilisation (IVF), it can be useful to predict the number of eggs you’ll release as well as the dosage of medication to stimulate the ovaries. 

If you receive a low AMH result, this can be a sign that your ovarian reserve is decreasing, which may affect your fertility. In these cases, your fertility doctor may recommend a follow-up ultrasound scan (antral follicle count), where a doctor counts the activated follicles within your ovaries. 

Our AMH test can also help signal some reproductive health conditions. For instance, a high AMH level can be an indicator of polycystic ovary syndrome (PCOS), a hormonal condition which can affect your fertility.

 


What could
affect my results?

Some hormonal contraceptives, such as the pill or the implant, can falsely lower your result. Having polycystic ovary syndrome (PCOS) is also likely to lead to a falsely raised result. Other factors that may affect your AMH level include biotin supplements and previous ovarian surgery. For more information, please see our special instructions.

Hormones
Select profile for more information

Anti - Müllerian hormone Anti-Mullerian Hormone, or AMH, is a hormone produced by the ovaries. In particular, it is produced by the follicles which contain eggs within the ovary. Levels can indicate how high or low a woman's ovarian reserve is. Anti Mullerian Hormone is not routinely measured in men. It may be used by specialist fertility clinics in assessing sperm production.

How to prepare
for your test

Special instructions
Prepare for your anti-Müllerian Hormone (AMH) Blood Test by following these instructions. Hormonal contraception can affect this test; taking a break from this and using barrier contraception will give more accurate results. If you stop taking the pill, wait until your periods have resumed their normal cycle before taking this test. However, AMH levels don’t vary significantly throughout your menstrual cycle, so you can take this test at any point. Do not take biotin supplements for two days before this test; discuss this with your doctor if it’s prescribed.

Frequently asked questions

How can I increase my AMH level?

Although there are no guaranteed ways to increase your AMH levels, there are some natural methods that may help improve your ovarian reserve and fertility. There is some evidence to suggest that vitamin D supplements may increase your AMH level, but it’s difficult to know whether this has any direct effect on your ovarian reserve. Speak with your doctor about the best ways to improve your AMH levels and maximise your chances of conceiving. And you can find out more in our Fertility Guide

Can I get pregnant naturally with a low AMH level?

Yes, it’s still possible for you to get pregnant naturally with a low AMH level, although it may be more difficult with fewer remaining eggs. Some people with a low AMH level may still be able to conceive without any difficulty, while others may need fertility treatment such as IVF.

Where can I get an AMH test?

Your blood sample for our AMH Blood Test can be taken at home or at one of our convenient nationwide partner clinics, at a time that suits you.

Can I take the AMH test at home?

Yes, you can take our anti-Müllerian hormone test at home using our finger-prick blood test kit. We'll send you everything you need, including a pre-paid return envelope.

How can I check my AMH level at home?

Our at-home AMH test includes a full lab analysis of your blood sample and expert medical advice including any next steps.

Can I use this test to check my ovarian reserve?

AMH can give you an indication of your ovarian reserve. If a blood test shows that your AMH is lower than the normal range for your age, it may indicate that you have fewer eggs remaining. Read more about what AMH can tell you about your fertility

Risk factors for low ovarian reserve


Ovarian reserve naturally declines with age as you near menopause. Some women, however, can be diagnosed with diminished ovarian reserve, meaning the number and quality of their eggs is lower than expected for their age.


A low ovarian reserve can be down to several factors, including:


• Having a family history of early menopause/perimenopause
• Smoking
• Ovarian surgery (such as the removal of an ovary)
• Autoimmune conditions, including thyroid disease
• Pelvic infection
• Chemo- and radiotherapy

 

What can AMH tell you about your fertility?


If you’re starting fertility treatment or have decided to freeze some of your eggs, an AMH test can give you an estimate of your ovarian reserve (how many eggs you have left). If your result is very low, it could mean you’re more likely to reach menopause early and you may decide to bring your family planning timeline forward.

What is a normal AMH level for my age?

 

Your AMH level naturally decreases as you get older, so a ‘good’ AMH level will depend on your age and other factors, like your medical history and medications. While there is no universal agreement on normal AMH levels, most laboratories provide a range based on women’s average AMH levels per age group.

Generally, a higher AMH result points to a greater ovarian reserve, but if your result is too high, it could point to polycystic ovary syndrome (PCOS).

The table below can help you understand how typical AMH levels vary according to age. These ranges are representative, and the interpretation of your results will vary according to individual factors.

Age RangeTypical AMH level (pmol/L)
20–248.7–83.6
25–296.4–70.3
30–344.1–58.0
35–391.1–53.5
40–440.2–39.1
