To read the full abstract: Proc Natl Acad Sci U S A. 2019; 116(44): 22294-22299. PMID: 31611378.Androgen biosynthesis in the human fetus proceeds through the adrenal sex steroid precursor dehydroepiandrosterone (DHEA), which is converted to testosterone in the gonads, followed by further activation to 5α-dihydrotestosterone (DHT) in genital skin, thereby facilitating male external genit...

Brief summary: In this cross-sectional study, 11-oxygenated androgens were measured in morning serum samples from 290 healthy adults (125 men, age 22–95 years; 165 women, age 21–91 years) by LC–MSMS (liquid chromatography, tandem mass spectrometry) to generate normative values across the lifespan. In a subset of volunteers (n=83), additional measurements were performed in saliva to assess diurnal and menstrual cycle-dependent variation. In general, it w...

Brief summary: This study validates dexamethasone-suppressed [11C]metomidate positron emission tomography computed tomography (MTO) scanning as a CYP11B2-selective investigation for lateralizing PA.Primary aldosteronism (PA) is the most common single cause of hypertension, accounting for 5–14% of all cases and 20–25% of treatment-resistant hypertension (1, 2). Traditionally, patients with PA are divided equally into ...
