Understanding the Egg Timer Test – What is Ovarian Reserve & AMH?

Ovarian Reserve and Anti-Mullerian Hormone (AMH)  are two fertility terms that you might come across quite often when you’re trying for a baby, and rightly so, because they are extremely important things. But what exactly are they? Let’s delve in to what ovarian reserve is and how knowledge of your AMH can really assist when trying to have a baby.

Ovarian reserve is the term used to describe the number of good quality eggs left within a woman’s ovaries. Women are born with all the eggs they’ll ever have, which is approximately 1 million. The number of eggs decline naturally with age and through ovulation (when you release an egg as part of your menstrual cycle).The rate eggs decline is different for every woman, with around 10% of women experiencing an accelerated loss where eggs decline at a faster than normal rate. As a woman runs out of eggs, the number of these small antral follicles (measure of egg supply for the future) decline in number and as a result the serum Anti-Mullerian Hormone (AMH) falls.

Women with diminished ovarian reserve may have diminished fertility and an increased risk of miscarriage. It is important to us to identify this in women early on so that they can make decisions on when to start having a family and when to access assisted reproductive technology if required. We are able to help identify this in women through an AMH blood test, otherwise known as the Egg Timer Test.

Egg Timer Test – FAQ’s.

What is the egg timer test?

A simple blood test can measure your ovarian reserve. Known as the egg timer test, the blood test measures Anti-Mullerian Hormone (AMH), and gives a good indication of your fertility and remaining eggs.

What if my ovarian reserve is low?

  • If you’re in a relationship and ready for children, we recommend you try to get pregnant as soon as possible.
  • You can freeze your eggs.
  • If you’ve experienced premature menopause, we can talk about options including using donor eggs.

At what time in the menstrual cycle should AMH be taken?

Anti-Mullerian hormone levels fluctuate very little during the menstrual cycle and therefore can be taken at any time during a normal menstrual cycle.

Should I have the egg timer test?

Women under the age of 38 years who are considering delaying pregnancy, women with a family history of ovarian failure, autoimmune disease, chemotherapy or previous surgery to the ovaries are all well suited to ovarian reserve testing, otherwise known as the Egg Timer Test.

Information is power and lets you take charge of your fertility.

Women and couples can delay starting a family for all kinds of reasons, but there’s no question fertility declines with age. Once the ovaries run out of eggs, the body can’t produce more. The last remaining eggs may not be great quality – so it’s best to make an informed decision. The Egg Timer Test can help with this.
