Understanding the Anti-Müllerian Hormone (AMH) Test: A Simple Guide

marvel img

The Anti-Müllerian Hormone (AMH) test is an important tool used in assessing a woman's reproductive health. This hormone, produced by the small follicles in the ovaries, provides valuable information about a woman's ovarian reserve, which is a fancy way of saying how many eggs she has left. This blog will break down what the AMH test is, why it’s important, and what the results might mean for you.

What is an AMH test?

An AMH test measures the level of anti-Müllerian hormone in a blood sample. In males, AMH is produced by the testicles, which generate sperm and male hormones. In females, the ovaries produce AMH, where eggs and female hormones are formed.

AMH serves different functions in males and females, and normal AMH levels vary by sex and age. Measuring AMH can help diagnose various reproductive health conditions.

In unborn babies, AMH helps develop reproductive organs. Male babies have XY chromosomes and produce high levels of AMH to form male reproductive organs. Female babies have XX chromosomes and produce low levels of AMH, allowing the formation of female reproductive organs. AMH levels in males remain high until puberty and then decline. In females, AMH levels increase during puberty and decrease with age, reaching zero at menopause.


Other Names:

  • AMH hormone test
  • Müllerian-inhibiting hormone (MIH)
  • Müllerian inhibiting factor (MIF)
  • Müllerian-inhibiting substance (MIS)


What Is It Used For?

AMH tests are primarily used to assist in treating female infertility. They help:

Assess ovarian reserve (how many eggs are left in the ovaries).
Predict response to fertility treatments, such as IVF.
Diagnose and monitor ovarian conditions like PCOS and certain ovarian cancers.

For Babies And Children, AMH Tests Can:

Check for healthy testicles in male babies with undescended testicles.
Help diagnose atypical genitalia in newborns by determining if there is functioning testicular tissue.

Why Do I Need An AMH Test?

Women May Need An AMH Test If They:


  1. Have fertility issues.
  2. Are planning IVF treatment.
  3. Show symptoms of PCOS.
  4. Are being treated for ovarian cancer.
  5. Male babies or children might need an AMH test to check for undescended testicles or to diagnose the cause of atypical genitalia.


What Happens During An AMH Test?

A clinician will collect a blood sample from a vein in your arm.

This usually takes less than five minutes and may cause a slight sting or bruise.


Preparation And Risks:

No special preparations are needed for an AMH test. The risks are minimal, with possible slight pain or bruising at the needle site.


Understanding Results:

The Meaning Of AMH Test Results Varies:


  1. Fertility: High AMH indicates a larger egg reserve, while low AMH suggests a shrinking egg supply.
  2. PCOS: High AMH may indicate PCOS, but further tests are required for diagnosis.
  3. Menopause: Low AMH can signify approaching menopause, but it cannot predict the exact timing.
  4. Ovarian Cancer: Decreasing AMH levels may indicate effective treatment, while increasing levels might suggest the cancer has returned.
  5. Undescended Testicles in Males: Normal AMH levels mean the testicles are functioning but not in the correct position. Low or no AMH indicates potential issues with testicular development.


FAQs About the AMH Test

1. When should I get an AMH test?

ANS. You can get an AMH test at any point in your menstrual cycle since AMH levels do not fluctuate much. It's particularly useful if you’re experiencing fertility issues or planning for future conception.

2. How is the AMH test performed?

ANS. The test is a simple blood draw. A healthcare provider will take a sample of your blood, which is then analyzed in a lab to measure the AMH levels.

3. Do I need to prepare for the AMH test?

ANS. No special preparation is needed. You don’t need to fast or schedule the test for a specific day in your cycle.

Q.4. Are there any risks associated with the AMH test?

ANS. The AMH test is very safe. The only risks are those associated with a standard blood draw, such as slight bruising or discomfort at the site where blood is taken.

Q.5. What do I do if my AMH levels are low?

ANS. If your AMH levels are low, it’s a good idea to discuss the results with your doctor. They might suggest further tests or recommend seeing a fertility specialist to explore your options.



The AMH test is a straightforward, yet powerful tool in understanding your reproductive health. Whether you're planning to start a family, considering fertility treatments, or simply curious about your ovarian reserve, the AMH test can provide valuable insights. Remember, while AMH is an important marker, it's one piece of the fertility puzzle, and discussing your results with a healthcare provider is always the best course of action.


Taking control of your reproductive health starts with knowledge, and the AMH test is a great step in the right direction!
