Background: Extensive and time-consuming hormonal and genetic work-up provides a genetic diagnosis in around 20% of 46,XY cases with ambiguous genitalia. It is currently unclear if such extensive screening might also be indicated in 46,XY newborns with milder undervirilization.Method: All 46,XY neonates and infants (n=32, EMS 2–12) referred to our pediatric endocrine service for atypical male genitalia in the period 2007–2013 were inve...

Background: The ‘External Masculinization Score’ (EMS) is an objective method of scoring undervirilized genitalia in infants but may require further adaptation to capture the appearance of the genitalia more comprehensively across the phenotypic spectrum.Objective: To develop and validate a non-binary, standardized score that describes the range of appearance of external genitalia.Method: The external genitalia score (EGS...

Background: Partial Androgen insensitivity syndrome (PAIS) is a rare condition which is associated with a variable phenotype. To date, there are limited data reporting long-term endocrine outcome for this condition.Aims: To determine the outcomes and clinical characteristics for 46, XY males with PAIS, using information from the International DSD (I-DSD) Registry and its clinical users.Methods: The I-DSD Registry and its users were...

Introduction: Depending on the underlying diagnosis, Disorders of Sex Development (DSD) can be associated with an increased risk of germ cell cancers. To date, however, knowledge regarding the indications and timing of gonadectomy is lacking.Methods: The International-DSD (I-DSD) Registry was interrogated for anonymised information regarding the diagnosis, karyotype, sex of rearing and timing of gonadectomy, if undertaken, of all individuals of any karyo...
