In multivariable‐adjusted logistic regression, age (p = 0.03) and AMH (p = 0.03) at 12 months, and gBRCApv status (p = 0.03) at 18 months were significant predictors of amenorrhea (areas under the ROC curve of 0.77 and 0.76, for 12 and 18 months, respectively) among 102 evaluable subjects. Here, AMH is linked to amenorrhea.
