The reported 68%-86% overall success rates for sex reassignment surgery must be viewed cautiously; the lack of long-term follow-up studies makes these statistics misleading. There is evidence suggesting that some gender dysphoric patients benefit primarily from sex reassignment surgery. Most such patients, however, are secondary transsexuals who can benefit from various modes of psychotherapy. Sex reassignment surgery should only be considered as the last resort for a highly select group of diagnosed gender dysphoric patients. As physicians learn new ways to diagnose and treat transsexualism, either sex reassignment surgery will be abandoned as a routine treatment modality or new predictive variables for choosing suitable patients for sex reassignment surgery will be established.
对于变性手术所报道的68% - 86%的总体成功率必须谨慎看待；缺乏长期随访研究使得这些统计数据具有误导性。有证据表明，一些性别焦虑症患者主要从变性手术中获益。然而，大多数这类患者是继发性易性癖者，他们可从各种心理治疗方式中获益。变性手术应仅被视为一小部分经诊断的性别焦虑症患者的最后选择。随着医生们学习诊断和治疗易性癖的新方法，要么变性手术将被作为一种常规治疗方式摒弃，要么将建立新的预测变量以挑选适合进行变性手术的患者。
