Metabolite Identification
Common NamePregnanediol
DescriptionPregnanediol is an endogenous human testosterone metabolite. It can be detected in adults and newborns urine in variable concentrations. Pregnanediol is abnormally elevated in patients with cytochrome P450 (P450C17, steroid 17alpha-monooxygenase, EC oxidoreductase deficiency (Antley-Bixler syndrome, PORD, OMIM 201750 ). Antley-Bixler syndrome is a multiple congenital malformation syndrome with craniosynostosis, radiohumeral synostosis, femoral bowing, choanal atresia or stenosis, joint contractures, urogenital abnormalities and, often, early death. An assay of urinary pregnanediol excretion provides an accurate indication of outcome in threatened abortion in 74 - 93% per cent of cases. Pregnanediol is one of the most important markers of pregnenolone administration, which can potentially be abused by athletes to maintain an equilibration of the steroidal environment after sex steroids administrations. Patients with recurrent vulvovaginal candidiasis have significantly lower levels of urinary pregnanediol.
