[Psychosocial and biological aspects of transsexualism].

This study is an attempt at approximating the question of transsexualism as a psycho-biological and socio-legal problem. The authors point out the role of genetic factors in sex determination and sexual features' differentiation. Social and educational environment plays a great role in forming of a psychical sex. However, the subjective feeling of sex is most probably biologically conditioned. Recognition of the problems connected with transsexualism may contribute to an improvement in quality of life of individuals suffering from disorders of sexual identification.
