Disorders of sex development (DSD) are a diverse group of conditions where the chromosomal, gonadal or anatomical sex can be atypical. DSDs are caused either by disruption of sex differentiation due to defects in hormone production/sensitivity, or by alterations in the pathway responsible for determining gonadal development.
