Intersex condition and the construction of gender identity.

Intersexuality is conceptualized as a disorder of sexual development (DSD), which includes congenital conditions associated with atypical chromosomal, gonadic and anatomic sexual development. DSD can be diagnosed at birth as a result of observation of ambiguous genitalia, or, in adolescence, if sexual development diverges from the assigned gender. Some DSD can only be recognized in adulthood as a consequence of reproductive difficulties. In children and adolescents with DSD, gender identity is strongly influenced by atypical sexual development. The comparison between two management models of DSD, the optimal gender policy and a holistic perspective focused on the individual, highlighted their differences with regard to effects on individuals with DSD.
