The ICD is an international version of the DSM. According to the HBSOC: The purpose of the DSM-IV and ICD-10 is to organize and guide treatment and research. These nomenclatures were created at different times and driven by different professional groups through a consensus process. There is an expectation that the differences between the systems will be eliminated by the year 2000. At this point, the specific diagnoses are based to a larger extent on clinical reasoning than on scientific investigation. It has not been sufficiently studied, for instance, whether sexual attraction patterns predict whether or not a patient will be a mentally healthier person in five years with or without the triadic sequence. The ICD-10 now provides five diagnoses for the gender identity disorders.

ICD - 10

Transsexualism (F64.0) has three criteria:

The desire to live and be accepted as a member of the opposite sex, usually accompanied by the wish to make his or her body as congruent as possible with the preferred sex through surgery and hormone treatment The transsexual identity has been present persistently for at least two years The disorder is not a symptom of another mental disorder or a chromosomal abnormality

Dual-role Transvestism (F64.1) has three criteria:

The individual wears clothes of the opposite sex in order to experience temporary membership in the opposite sex There is no sexual motivation for the cross-dressing The individual has no desire for a permanent change to the opposite sex

Gender Identity Disorder of Childhood (64.2) has separate criteria for girls and for boys.

Either of the following must be present: persistent marked aversion to normative feminine clothing and insistence on wearing stereotypical masculine clothing persistent repudiation of female anatomical structures, as evidenced by at least one of the following: an assertion that she has, or will grow, a penis rejection of urination in a sitting position assertion that she does not want to grow breasts or menstruate 3.
