Different forms of intersexuality (Disorders of Sex Development, DSD) are described (congenital adrenal hyperplasia, androgen insensitivity, disorders of androgen biosynthesis, gonadal dysgenesis). Treatment interventions for individuals with ambiguous genitalia and untypical sex development are discussed with respect to medical and psychosocial aspects considering the consensus paper on the management of subjects with intersexuality. The role of gender identity, gender role and sexual orientation are presented as well as problems of disclosure and gender change. Further research is needed to evaluate the optimal treatment procedures.
