Current guidelines for gender assignment for all 46,XX congenital adrenal hyperplasia (CAH) continue to be female. This decision is most challenging for individuals with a 46,XX karyotype born with (CAH) having severely masculin-ized genitalia (Prader 4 or 5). They may be at significant risk for quality of life (QoL) and psychological health. More outcome information currently exists for such individuals assigned male than female. Most available data for those raised females do not indicate the extent of masculinization at birth, so there are minimal outcome data to compare with those raised males. Gender dissatisfaction among those raised females may be related to the degree of prenatal androgen excess in the brain evidenced by external genital masculinization. Also, additional brain maturation after birth, especially during puberty, is impacted by postnatal androgen excess resulting from inadequate androgen sup-pression. The purpose of this perspective is to suggest that both female and male assignment be considered. Most who have been raised male at birth have positive adult outcomes. This consideration should occur after discussions with full disclosure to the parents. The lack of more outcome data highlights the need for further information. This perspective also suggests that surgery should be deferred whether assigned female or male at least until gender identity is apparent to preserve the potential for male sexual function and prevent irrevocable loss of sensitive erotic tissue. While the gender fluidity is recognized, it is important to consider potential subsequent need for gender reassignment and extent of masculinization, particularly at the time of gender determination.
