What Is AMH Used For?

AMH is primarily used to evaluate ovarian reserve in women, helping determine the likelihood of natural conception or the need for fertility treatments. In men, it may assess testicular function or sperm production.

Who Might Need This Test?

Women undergoing fertility evaluations, those experiencing unexplained infertility, or those approaching menopause may have AMH tested. Men with suspected low sperm production or fertility concerns might also have this test.

How Is the Test Performed?

A blood sample is drawn from a vein in your arm. The sample is then sent to a lab for analysis using an immunoassay method to measure AMH levels.

What Are Common Results and Interpretation?

Results are compared to reference ranges for your age and sex, though specific ranges can vary. Higher levels may indicate better ovarian or testicular reserve, while lower levels could suggest diminished reproductive capacity.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance: AMH plays a critical role in fertility assessment. In women, it reflects the number of remaining eggs, helping guide decisions about fertility treatments or timing of pregnancy attempts. In men, it may help diagnose conditions affecting sperm production.

Short name

AMH (Anti-Müllerian Hormone)

Frequently asked questions

Why might my doctor order this test?
Your doctor may recommend AMH testing if you have concerns about fertility, unexplained infertility, or if you’re exploring options like egg freezing or fertility treatments.
What do my AMH results mean for my fertility?
AMH results help estimate your ovarian or testicular reserve but don’t predict pregnancy success alone. They’re used alongside other tests and clinical factors to guide treatment plans.
Can AMH levels change over time?
Yes, AMH levels can decline with age, especially in women as they approach menopause. In men, levels may fluctuate due to underlying health conditions or hormonal imbalances.
