An AMH Result Is Not a Stand-Alone Fertility Forecast

If an AMH report has left you wondering whether pregnancy is possible, ask the clinician to explain what the test was intended to assess before using it to judge your chance of pregnancy. Bring the exact report and the question that led to testing.

What is being measured?

Anti-Müllerian hormone, or AMH, is a marker of ovarian reserve. ASRM defines reserve as egg quantity, distinct from egg quality. Its 2020 committee opinion explains that reserve markers can help predict the number of eggs obtained after ovarian stimulation, but poorly predict reproductive potential independently of age.¹

Ask: “Was this ordered to help plan fertility treatment, or to answer a different question?” Have the clinician explain how the result fits your history and the decision you are making.

Does the evidence support a personal pregnancy forecast?

The opinion reports that reserve markers poorly predicted reproductive potential in prospective studies of women with unproven fertility. It advises against using them as fertility tests in that setting. A diminished-reserve result does not necessarily mean inability to conceive; it also does not promise pregnancy.¹

If you are trying to conceive, describe how long you have been trying and what assessment has already happened. Ask which information is still needed. If you have not tried, explain your plans rather than treating the report as a deadline by itself.

Why can the test still matter in treatment planning?

ASRM finds that AMH can predict egg yield and ovarian responsiveness in IVF, with only a weak relationship to outcomes such as egg quality, clinical pregnancy and live birth. The opinion says extremely low AMH should not be used to refuse IVF treatment. Individual counseling remains essential.¹

Ask the fertility team to distinguish the response they expect from stimulation from the chance of pregnancy. Request an explanation of the uncertainties and appropriate options for your circumstances before deciding what to do next.

What context should you bring to the result review?

AMH may be lower in people currently using hormonal contraception, so ASRM recommends cautious interpretation in that situation. Tell the clinician which product you use; do not pause contraception yourself to change a test result.¹

Bring the full laboratory report, current medicines and the cycle history you want discussed. Ask whether the result changes the proposed plan, who will explain any additional findings and when you will review the options.

Period, Handled includes a Period Scorecard and visit script. Use them to organize cycle observations and the questions you want answered. Your clinical team interprets the AMH result and any other assessment. See the book.
