Frequency figures for transsexualism, concerning incidence, prevalence and sex ratio calculated in the 1960s and 1970s, were compared with recent reports. The incidence figures remained constant over time, whereas the prevalence figures tended to increase during the review period. The incidence was found to be of the same magnitude in men and women, while the corresponding ratio for prevalence figures was 3:1. It is suggested that men seeking sex reassignment represent a more heterogeneous group than women, and that the reported male predominance to date is due to a lack of categorical studies of primary/ genuine transsexualism. It would appear that genuine transsexualism is, on the whole, insensitive to societal changes. The fundamental disturbance underlying this psychosexual identity disorder is suggested to be neurobiological in origin.
将20世纪60年代和70年代计算出的关于易性癖的发病率、患病率及性别比的频次数据与近期报告进行了比较。发病率数据随时间保持稳定，而在审查期间患病率数据呈上升趋势。发现男性和女性的发病率处于同一数量级，而患病率的相应比例为3:1。有人认为，寻求性别重置的男性群体比女性群体更加多样化，并且迄今为止报告的男性占主导地位是由于缺乏对原发性/真性易性癖的分类研究。看起来，总体而言，真性易性癖对社会变化不敏感。这种性心理身份障碍潜在的根本障碍被认为起源于神经生物学。
