AMH and Ovarian Reserve Testing
AMH (Anti-Müllerian Hormone) is a blood test commonly used to estimate ovarian reserve — a general indicator of the number of eggs remaining, not their quality.

Direct answer
AMH (Anti-Müllerian Hormone) is a blood test commonly used to estimate ovarian reserve — a general indicator of the number of eggs remaining, not their quality. It's one piece of information a specialist may use, alongside age, cycle history, and other factors, to help understand a person's fertility picture. AMH results are not a standalone diagnosis and are best interpreted together with a specialist.
What AMH testing measures
AMH is produced by small follicles in the ovaries, and its blood level is generally used as an indirect estimate of how many eggs remain. It's a single blood test that can be done at any point in the menstrual cycle, which makes it a convenient first step compared to some other fertility tests.
What AMH does and doesn't tell you
AMH gives information about egg quantity (ovarian reserve), not egg quality. A normal AMH level doesn't guarantee easy conception, and a lower-than-typical AMH level doesn't mean conception isn't possible — it's one data point among several a specialist considers, not a definitive prediction on its own.
Who may be recommended an AMH test
A specialist may recommend AMH testing as part of a general fertility evaluation, before starting IVF (to help plan medication dosing), or for people wanting to understand their fertility timeline for personal planning, including before considering egg freezing. The decision to test, and how to interpret results, is individualized.
Factors that can influence AMH levels
AMH levels are generally understood to decline with age, though the rate can vary between individuals. Certain medical conditions (such as PCOS), medications, and prior ovarian surgery, chemo/radiotherapy can also affect levels. A specialist can help interpret an individual result in the context of overall history, rather than looking at the number alone.
Common questions about AMH testing
Is a low AMH level a diagnosis of infertility?
No. AMH is one indicator of ovarian reserve, not a diagnosis. A specialist considers it alongside other factors before drawing conclusions.
Can AMH levels change over time?
AMH is generally understood to decline gradually with age. Short-term fluctuation and what a specific trend means for an individual is best discussed directly with a specialist.
Does a high AMH level mean better fertility?
Not necessarily — a very high AMH can sometimes be associated with certain conditions (such as PCOS) rather than simply indicating "better" fertility. Interpretation depends on the full clinical picture.
Should AMH testing be done regularly?
This depends on individual circumstances and goals; a specialist can advise on whether and how often retesting makes sense for a given situation.
When to reach out
If you're curious about your ovarian reserve, have been advised to get an AMH test, or want help interpreting a result you already have, a consultation is the right next step.
FAQs
Is AMH testing painful?
It's a standard blood draw, similar to other routine blood tests.
Do I need to fast before an AMH test?
Fasting requirements can vary by lab; check with the clinic or lab directly for specific instructions.
Can men have an AMH test?
AMH testing in the context of fertility evaluation is generally associated with ovarian reserve in women; male fertility evaluation uses different tests (see our related article on male infertility evaluation).
Is AMH the only test used to assess fertility potential?
No — AMH is one of several tools a specialist may use, alongside age, cycle history, ultrasound findings, and other factors, to build a fuller picture.
