[Medical jurisprudence problems raised by transsexualism in 1986. Apropos of 148 cases of gender dysphoria].

The authors review the classification of transsexualism and gender dysphoria with respect to a series of 148 patients followed up for 10 years by a multidisciplinary group of endocrinologists, surgeons and psychiatrists; transsexualism is a major problem of self-identity and not a sexual derivation. The principal features of the study population are presented with details of methodology, criteria for selection for sex change treatment, and results obtained. The two main medicolegal problems (changing civil identity and penal medical responsibility) posed by medico-surgical treatment in France are discussed.
