Objective: Quantify classic and 11-oxygenated androgens in serum and saliva and determine variations across age, sex, body mass index (BMI), menstruation and hormonal contraception use.Methods: Morning serum samples were collected from 292 healthy volunteers (125 men, 22-95 years; 167 women, 21-91 years). Morning saliva was collected from 83 healthy volunteers (51 women, 32 men). 25 individuals (12 women, 13 men) also collected a 7-timepoint diurnal sali...

Background: The gonads are the major source of classic androgens during reproductive years. Additionally, the adrenal gland produces precursors for both classic and 11-oxygenated androgen biosynthesis, with androgen activation predominantly occurring in peripheral target tissues of androgen action. We used liquid chromatography-tandem mass spectrometry to profile classic and 11-oxygenated androgens in serum and saliva across the adult age range and assessed diurnal as well as ...
