    Studysummary This study developed and validated a comprehensive method using mass spectrometry to profile sex (pro)hormones in plasma, with results showing reliable calibration and detection of 31 analytes in samples from pre- and postmenopausal women and men, while addressing potential over- or underestimations in analyte concentrations.
