At Manchester Fertility your AMH levels are tested as part of your initial screening when you begin treatment, via a simple blood test. But it can be hard to understand what AMH is and what your result means.

What is Anti-Müllerian Hormone (AMH)?

Anti-Müllerian Hormone (AMH)is a substance made by the ovarian follicle that contains the egg, and your AMH levels can help us identify the best course of treatment for you.  AMH levels will naturally decline with age. It can be measured on any day of your cycle and it does not vary from month to month. It is recommended that the test is repeated every year.

What will an AMH result tell me?

Your AMH result takes around one week to come through following your test.  In the table below are age related AMH values. As you can see, there is a lot of overlap in the age ranges.


 Age Range AMH (pmol/l)
 20-29 years 13.1 - 53.8
 30-34 years 6.8 - 47.8
 35 - 39 years 5.5 - 37.4
 40-44 years 0.7 - 21.2
 45 - 50 years 0.3 - 14.7

Once you have your result our Doctors will be happy to explain the result and give you relevant advice.

If your result comes back with a very low blood AMH level, this typically means you don’t have many available eggs. In this instance the chances of success through traditional IVF would be reduced because response to ovarian stimulation will likely be poor. But it doesn’t mean you can’t get pregnant. A very low AMH result it just means there aren’t lots of eggs. It doesn’t mean the ones you have aren’t good enough quality for pregnancy. 

What does it mean if I have a high AMH level?

But at the opposite end of the scale, if your blood shows a very high AMH level – above optimum levels - it means you have lots of follicles and this potentially puts you at risk of Ovarian Hyperstimulation Syndrome (OHSS), which is when you produce too many mature eggs. 

Whatever your result shows, please remember that your potential for conceiving is influenced by a number of factors, and AMH assessment is only a part of it. We will discuss treatment options with you in full once we know your AMH result, giving you a treatment plan with a protocol personal and individual to you.
