Key Knowledge Points about AMH:

Definition and Function:
AMH stands for Anti-Müllerian Hormone. It reflects a woman’s ovarian reserve (the quantity of remaining eggs), but it is not a direct measure of egg quality.

Testing Advantages:
AMH levels are not affected by the menstrual cycle, ovulation medications, or birth control pills. Therefore, the test can be performed at any time.

General Interpretation of AMH Levels:

· Normal range: 2–5 ng/mL

· High ovarian reserve: > 5 ng/mL (may be associated with polycystic ovary syndrome)

· Reduced ovarian reserve: < 1.5 ng/mL

· Premature ovarian insufficiency / Very low reserve: < 1 ng/mL (before age 40)

Relationship with Age:

AMH levels naturally decline with age. After age 40, it is typically < 1 ng/mL.

Who Should Consider AMH Testing:

· Women who are trying to conceive

· Women who want to assess their fertility potential

· Those considering egg freezing

· Women suspected of having polycystic ovary syndrome (PCOS) or premature ovarian insufficiency

Clinical Significance:
AMH is used to evaluate ovarian aging and helps predict ovarian response to stimulation. It also assists in determining medication dosage in assisted reproductive treatments, such as IVF.

Important Note:
A low AMH level indicates a lower egg quantity, but it does not necessarily mean pregnancy is impossible. Egg quality (primarily determined by age) is equally important.
