Background: The etiology of hypospadias may be at the crossroad of genetics and environment. The study of these factors taken individually failed to find an unequivocal explanation in most cases. But the interactions between exposure to endocrine disruptors chemicals (EDC) and genetic background have not yet been studied. We thus aimed to find a genetic susceptibility to the environment in hypospadias.Methods: Through a multicenter prospective comparativ...

The nuclear receptor steroidogenic factor 1 (SF1/AdBP4/FTZF1, NR5A1) is a key regulator of adrenal and gonadal development, steroidogenesis and reproduction, and targeted deletion of Nr5a1 (Sf1) in the mouse results in adrenal and gonadal agenesis, XY sex-reversal and persistent Müllerian structures in males. Consistent with this phenotype, DNA-binding mutations in SF1 have been reported in two 46,XY female patients with primary adrenal failure and uterine s...

Disorders of sex development (DSD) include a conglomerate of rare conditions with discrepancy of the chromosomal, gonadal or phenotypic sex. Since the last 2 decades the genetic causes and the pathogenesis have been identified in many patients with DSD. Multidisciplinary clinical care as decision on the sex of rearing, genital surgery, hormone therapies and psychological support has a life-long impact on the affected persons. However, previous clinical outcome studies of DSD w...
