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.
新加坡易性癖的患病率是通过统计所有寻求性别重置手术并随后被精神科医生诊断为易性癖的患者来估算的。截至1986年,共有458名在新加坡出生的易性癖者,其中男性343人,女性115人。男性易性癖的患病率为每10万15岁及以上人口中有35.2人(或1/2900),女性易性癖的患病率为每10万人口中有12.0人(或1/8300)。男女比例约为3比1。患病率高的主要原因是可进行性别重置手术。
