Individuals with a congenital discrepancy between external genitalia and gonadal and chromosomal sex are classified as having a disorder of sex development (DSD) [1]. Many of these individuals present as newborns with an atypical genital appearance often termed "ambiguous genitalia". The birth of an infant with ambiguous genitalia presents a unique set of challenging management issues.

Psychosexual development is influenced by multiple factors including:

Genes involved in sexual development

Gender differences in brain structure

Prenatal androgen exposure
