To read the full abstract: Sci Rep. 2017; 7(1): 7427Prenatal dexamethasone treatment has been suggested over three decades ago to prevent virilization of a female fetus affected with 21-hydroxylase deficiency due to genetic mutations in the CYP21A2 gene. However, current treatment guidelines for CAH regard this treatment still as experimental, mainly because follow-up studies of treated fetu...
