The prevalence of transsexualism in Singapore

Abstract

The prevalence of transsexualism in Singapore was estimated by counting all the patients who sought sex-reassignment surgery and were subsequently diagnosed as transsexuals by psychiatrists. Up to 1986, there were a total of 458 Singapore-born transsexuals, of which 343 were males and 115 were females. This was a prevalence of 35.2 per 100,000 population age 15 and above (or 1/2900) for male transsexualism, and 12.0 per 100,000 (or 1/8300) for female transsexualism. The sex ratio was about 3 males to 1 female. The main reason for the high prevalence was the availability of sex-reassignment surgery.
