How are AMH and menopause related?

AMH (Anti-Müllerian Hormone) is produced by small growing follicles in the ovaries and reflects the remaining egg supply. As women age, AMH levels decline steadily and become undetectable after menopause. Strong human evidence from prospective cohort studies shows that AMH is a reliable biomarker of ovarian reserve and can help estimate the timing of menopause, though with considerable individual variation. A very low AMH level in a woman over 40 suggests menopause is approaching, but it is not a diagnostic criterion on its own. Menopause is clinically defined as 12 consecutive months without menstruation. AMH testing is therefore useful as a complementary tool for fertility planning or assessing reproductive lifespan, but it should not replace a full medical evaluation. The evidence is human-strong, based on large longitudinal studies. Caveats: prediction accuracy is lower in younger women, and hormonal contraceptives can suppress AMH levels, leading to false low readings. No direct safety concerns, but results should be interpreted by a healthcare professional.
