[Intersexuality not transsexuality. Delineation, new results, and proposals].

Physical and psychosocial aspects of intersexuality (disorders of sex development, DSD) are described here. Differences between intersexuality and transsexuality are elaborated upon, especially in terms of coping with the diagnosis and treatment recommendations when dealing with an "ambiguous" or "false" body and with the disclosure of the physical conditions. The results of the Hamburg evaluation study, which was carried out between 2002 and 2008 on intersex adults, are summarized. These results have formed the basis of the comprehensive interdisciplinary book Intersexualität kontrovers (Controversial Intersexuality ) published in 2012. An outline of the recommendations published in February 2012 by the German National Ethics Committee (Deutscher Ethikrat) on Intersexuality is also provided. Finally, the "dangers" of sex reassignment and gender change are questioned and an opening up of the binary view of sex and gender is proposed.
