Anti Mullerian Hormone (AMH) Test & Ovarian Reserve
Egg reserve test
Women are born with their lifetime supply of eggs, and these gradually decrease in both quality and quantity with age.
Anti-Mullerian Hormone (AMH) is a hormone secreted by cells in developing egg sacs (follicles). The level of AMH in a woman's blood is generally a good indicator of her ovarian reserve. AMH does not change during your menstrual cycle, so the blood sample can be taken at any time of the month - even while you are using oral contraception.
- What will an AMH test tell me?
An AMH test gives us some insight into the remaining quantity of eggs and number of fertile years you may have, but it cannot tell us much about the quality of those eggs.
To interpret your results you should compare your own level with other women of the same age.
- Do I need an AMH test?
The AMH test is useful if:
- you have been trying to conceive for over six months, and want to check your ovarian reserve is appropriate for your age
- you are considering IVF or other fertility treatments, as low levels of AMH could indicate a potentially poor response to IVF. Conversely, a high level may indicate an exaggerated response to the IVF medication
- you have had chemotherapy or ovarian surgery and want to know if it has affected your future fertility
- you suspect an ovarian tumour
- you would like to conceive in the future, and just want to understand your current position
- How do I get an AMH test?
You will need to ask your GP for a referral to IVFAustralia for an AMH test. Then contact your nearest IVFAustralia clinic to have your blood taken. We analyse your results in our own specialised laboratory and send a copy of these results to your referring doctor.
If you are already an IVFAustralia patient your fertility specialist can organise an AMH test for you.
- How much does an AMH test cost?
The AMH test costs $80 and is not covered by Medicare.
- What if I have low AMH?
If you have a low AMH level, indicating poor egg reserve, your GP may consider referring you to a fertility specialist for further explanation or you can simply book an appointment with a fertility specialist to discuss your options.
It is important to remember, women who have a low ovarian reserve and women who have a high ovarian reserve fall pregnant naturally at exactly the same rate. The reason for this is that both groups ovulate one egg per month and AMH is not an indicator of egg quality.
However, AMH is a useful tool to predict response with IVF, in terms of likely egg number that will be obtained in an IVF cycle. It can also give advanced warning that ovarian reserve is declining, prompting women to explore their reproductive options sooner.
