Brief Summary:
The physical and psychological effects of the hormonal treatment of transsexual persons are not sufficiently described. 'Transparency' wants to answer this question in a prospective manner, in a multicenter study to describe these effects. The low prevalence of transsexualism was the stimulus to search for European partners for this Protocol. A common standardized hormonal protocol was designed.
