In 2005, an international group of health-care experts, researchers, and patient advocates convened in Chicago to formulate a consensus on the clinical care of persons born with intersex conditions. The Consensus Statement on Management of Intersex Disorders, published in 2006, recommended eliminating confusing and potentially stigmatizing terms such as "intersex," "pseudohermaphroditism," "hermaphroditism," and "sex reversal" to refer to these conditions. The conference summary (hereafter referred to as the Consensus Statement)-adopted by the American Academy of Pediatrics as a policy statementincorporated all variations in somatic sex development under the umbrella term Disorders of Sex Development (DSD), defined as "congenital conditions in which development of chromosomal, gonadal, or anatomic sex is atypical" (Lee, Houk, Ahmed, Hughes, & in collaboration with the participants in the International Consensus Conference on Intersex organized by the Lawson Wilkins Pediatric Endocrine Society and the European Society for Paediatric Endocrinology, 2006). In the majority of the cases, DSD are detected at birth owing to atypical genital appearance; in other cases, the condition only becomes apparent at the time of puberty (e.g., failure to menstruate in girls with a 46,XY karyotype and Complete Androgen Insensitivity syndrome, CAIS). In both early-and late-diagnosed cases, one or more aspects of sex determination or differentiation is/are atypical. "Sex determination" refers to differentiation of the bipotential gonad into either testis or ovary and "sex differentiation" involves formation of the internal
