Anti-Müllerian fertility test

The key test to know your ovarian reserve

The antimüllerian fertility test measures the levels of anti-Müllerian hormone (AMH) in the blood, an essential marker for assessing a woman’s ovarian reserve. At Fertility Madrid, we carry out this test in a simple and quick way, providing precise information about current and future reproductive capacity. Knowing these values is fundamental for planning motherhood and deciding the most appropriate time to start a fertility treatment.

What is Anti-Müllerian Hormone (AMH) and what does it measure?

Anti-Müllerian Hormone (AMH) is a substance produced by ovarian follicles. Its level in the blood allows us to accurately determine the ovarian reserve, meaning how many eggs remain in the ovaries.

As women age, AMH levels naturally decrease. After the age of 35, this decline accelerates, which also reduces the chances of achieving pregnancy.

This test has become an essential tool in assisted reproduction, as it helps predict the ovarian response to hormonal stimulation and supports the decision of whether it is the right time to preserve eggs or begin a fertility treatment.

Why is it important to know your ovarian reserve?

Knowing your AMH levels allows you to:

  • Understand how many eggs you currently have.
  • Plan your motherhood in an informed way.
  • Decide whether you should vitrify eggs.
  • Choose the best moment to try for pregnancy.
  • Anticipate the success of fertility treatments.

For women who have undergone cancer treatments (radiotherapy or chemotherapy), AMH also helps assess ovarian damage.

How is the Anti-Müllerian Hormone (AMH) test performed?

At Fertility Madrid, the AMH test is done through a simple blood test.

  • No fasting is required.
  • It can be done on any day of the menstrual cycle.

This analysis measures your AMH levels precisely, offering a clear view of your fertility.

 

Reference values

  • Normal ovarian reserve: levels between 1–3 ng/ml

  • Good ovarian reserve: above 3 ng/ml

  • Low ovarian reserve: below 0.9 ng/ml

  • Very low ovarian reserve: < 0.5 ng/ml

AMH levels (ng/ml)

Ovarian reserve
≥ 3 Good
1–3 Normal
< 1 Low
< 0,5 Very low
 

When is it recommended to do the AMH test?

This test is especially useful in the following cases:

  • Women aged 30–35+ who want to become mothers in the future.
  • Patients with irregular periods or family history of early menopause.
  • Before starting fertility treatment.
  • Women with endometriosis or ovarian surgery history.
  • For fertility preservation treatments (egg vitrification).

What are the advantages of this test compared to others?

  • Can be done at any time during the menstrual cycle.
  • Does not require fasting or ultrasound.
  • Provides more stable and precise information than other hormones like FSH.

FAQs about the Anti-Müllerian Fertility Test

Do I need to fast for the test?

No, fasting is not required.

When is the best time to take the test?

The Anti-Müllerian Hormone (AMH) test can be performed at any time of the menstrual cycle, unlike other tests such as FSH, which must be done on a specific day (usually day 3 of the cycle).

Is the AMH test reliable?

Yes. It is one of the most reliable and stable tests to evaluate ovarian reserve.

Do contraceptives have an influence?

Some studies indicate that hormonal contraceptives may temporarily lower AMH levels. Therefore, if you are taking contraceptives, consult your doctor before having the test.

What should I do if my levels are low?

Our specialists will explain the available options: egg vitrification, starting treatment, or short-term planning.

Does Anti-Müllerian Hormone (AMH) predict egg quality?

No. AMH measures the approximate quantity of eggs available, but it does not determine egg quality. Quality depends mainly on the woman’s age.

Does AMH change over time?

Yes. AMH levels progressively decrease as a woman approaches menopause. That’s why this test is useful for assessing each patient’s reproductive stage.

Is the AMH test useful for fertility preservation?

Yes. AMH helps determine whether it is advisable to vitrify eggs early, in order to increase the chances of success in the future.

Can high AMH indicate problems such as polycystic ovary syndrome (PCOS)?

Yes. Elevated AMH values are often found in women with PCOS, since they tend to have a higher number of follicles in the ovaries.

How often should I repeat the AMH test?

It depends on each case. In young women without reproductive issues, a single test may be enough. If planning motherhood in the medium or long term, or if risk factors are present, it can be repeated every 1–2 years.

Does the AMH test replace the gynecological ultrasound?

No. Although it is very accurate, the ideal approach is to combine it with a transvaginal ultrasound of the antral follicle count (AFC) to obtain a complete assessment of ovarian reserve.
