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, what your result means and how it affects the chances of your treatment being successful.
What is AMH?
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. It can tell us how well you will respond to ovarian stimulation and give us an indication of how many eggs you have in your ovaries – your ovarian reserve.
What will an AMH result tell me?
Your AMH result takes around one week to come through following your test, and will be categorised as either optimal fertility, satisfactory fertility, low fertility or very low fertility.
Limits are usually:
- 40.03-67.9 pmol/l = Optimal fertility
- 21.97-40.03 pmol/l = Satisfactory fertility
- 3.07-21.97 pmol/l = Low fertility
- 0.0-3.07 pmol/l = Very low fertility
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 personal treatment plan with a protocol personal and individual to you.
