Background: The classical steroidogenic route to the synthesis of dihydrotestosterone in Leydig cells involves delta-5 and delta-4 precursors. Besides, the “backdoor pathway”, encompassing progesterone metabolites, is gaining increasing interest in fetal development and men pathophysiology. Nowadays, liquid chromatography/tandem mass spectrometry (LC-MS/MS) is the ideal technique to simultaneously quantify large panels of steroids with elevated sensitivity and specif...
