AMH Blood Test
Why Would I Need an AMH Blood Test?
When it comes to fertility, the more knowledge you have, the easier it is to consider your options. Having an AMH blood test will help you understand where you’re at with your ovarian reserve and AMH levels.
High or normal levels of AMH may mean you have lots of eggs and will therefore respond better to IVF treatment, whereas low levels mean that your eggs are on the decline and may not respond as well to treatment.
Mostly, the reason women do this test is to plan and take charge of their fertility. As we know, not only do you have fewer eggs as you age, the quality of the eggs lessens over time. The value of knowing your ovarian reserve as it sits today is so that you can choose to do something about fertility now, soon, or later. It may help you decide to try to conceive as soon as possible, or, if a family is desired in the future, you may think it’s better to freeze your eggs.
With an overall picture, you can set realistic expectations when retrieving eggs and understand how you’ll respond to certain medicines for IVF and egg freezing. So, put simply, knowing where you’re at fertility-wise will help you make the best decisions for your future.
What is the ovarian reserve?
Your ovarian reserve is the number of eggs left in your ovaries.
Incredibly, women are born with around 1 million eggs - but your egg supply declines naturally with age and through ovulation (when you release an egg as part of your menstrual cycle).
The rate at which your egg supply declines varies, though - every woman is different. Around 10% of women will experience an accelerated loss, where their egg supply declines faster than normal .
If you’re thinking of trying for a baby, the AMH is a good place to start.
AMH is produced by granulosa cells in the developing early antral follicles of a woman’s ovaries. As your eggs decline, so do the number of antral follicles - and with them your level of AMH.
What Do I Do Once I Get My Results Back?
When you have your results, which should be about a week after testing, the results will be discussed with you. You’ll receive all the relevant advice and you can then consider and plan the next steps.
Knowing your numbers will empower you to make the best decisions when family planning. If your AMH levels or egg count is low you may look at options including , ICI (intracervical insemination), or . If due to a low egg count, it may be very difficult to achieve a pregnancy on your own, it doesn't mean it’s not possible. But, if you’ve been already trying to conceive for over 12 months then you may like to start looking into testing for fertility issues.
No matter what your results indicate, it’s good to remember that your fertility and potential to conceive are influenced by many different factors. The AMH test is just one of the first steps. With the results, we can help you create a plan that’s individual to your lifestyle, needs, and desires.
