The question of human sexuality and intersex dates back to Greco-Roman mythology. In the last decades, with the breakdown of preexisting sociocultural paradigms and concepts, and with the maturation of society, gender identity is no longer seen in the binary form of masculine and feminine, but within a spectrum. As a result of this, there is a growing number of lawsuits demanding name and sex registration rectification in individuals that present a divergence between the designated sex and their gender identity. The objective of this study is to determine the medical-expert technical criteria for judicial proceedings in cases of gender dysphoria, transsexualism and transvestitism. A non-systematic search was conducted in the Medline, Pubmed and Lilacs databases from 2000 to 2016, and a review of Legal Medicine books and current Brazilian legislation related to the subject. Biological sex is defined by anatomical and physiological characteristics, determined by chromosomes, gonads, internal genitalia, external genitalia, hormones and secondary characters, and gender identity as the consciousness of being a man or woman or another. Gender dysphoria is characterized by the incongruity between biological sex and gender identity, determining significant suffering of the individual. National legislation does not address issues related to gender dysphoria, motivating large discussions at the doctrinal and jurisprudential level. The suggested technical criteria are: the determination of the biological sex and the gender identity of the individual, the diagnosis of Gender Dysphoria, Transsexualism or Transvestism, through the parameters of DSM-5 and ICD-10. In the report the expert should provide a favorable opinion or not to change the first name for the psychosocial adequacy of the individual, and regarding the rectification of sex, considering that biological sex is immutable at DNA level, even with changes in the phenotype, should use terms that can reflect in a real way the specific condition of the person, encompassing the biological, psychic and social aspect.
