Context: Several statistical models were introduced for the prediction of age at menopause using a single measurement of anti-müllerian hormone (AMH); however, individual prediction is challenging and needs to be improved. Objective: The objective of this study was to determine whether multiple AMH measurements can improve the prediction of age at menopause. Design: All eligible reproductive-age women (n = 959) were selected from the Tehran Lipid and Glucose Study. The serum concentration of AMH was measured at the time of recruitment and twice after that at an average of 6-year intervals. An accelerated failure-time model with Weibull distribution was used to predict age at menopause, using a single AMH value vs a model that included the annual AMH decline rate. The adequacy of these models was assessed using C statistics. Results: The median follow-up period was 14 years, and 529 women reached menopause. Adding the annual decline rate to the model that included single AMH improved the model�s discrimination adequacy from 70 (95 CI: 67 to 71) to 78 (95 CI: 75 to 80) in terms of C statistics. The median of differences between actual and predicted age at menopause for the first model was �0.48 years and decreased to �0.21 in the model that included the decline rate. The predicted age at menopause for women with the same amount of age-specific AMH but an annual AMH decline rate of 95 percentiles was about one decade lower than in those with a decline rate of 5 percentiles. Conclusion: Prediction of age at menopause could be improved by multiple AMH measurements; it will be useful in identifying women at risk of early menopause. © Endocrine Society 2020.
