The higher incidence of man-to-woman transsexuals compared to woman-to-man transsexuals varies markedly from country to country. This is the first survey of the sex ratio to be made in Germany.
It covers 1785 patients who between 1964 and 1998 were diagnosed as transsexual at the four largest German centres offering treatment.
From 1970 to 1994 the sex ratio remained constant at 2:1 in favour of man-to-woman transsexuals. Over the past 4 years, however, it has altered considerably and reached 1.2:1.
Up to 1994 our results do not support the assumption that transsexualism is gradually becoming equally prevalent in both sexes. The drop in the sex ratio after 1994 can be explained either as a reduction of an overhang of male-to-female transsexuals or as an artificial phenomenon caused by recent developments in therapy and by the views of transsexuals' groups on the treatment they are offered.
男变女变性者的发病率高于女变男变性者，不同国家间差异显著。这是德国首次进行的性别比例调查。
该调查涵盖了1964年至1998年间在德国四个最大的提供治疗的中心被诊断为变性者的1785名患者。
1970年至1994年，性别比例保持在2:1不变，有利于男变女变性者。然而，在过去4年里，这一比例发生了显著变化，达到了1.2:1。
到1994年，我们的研究结果不支持变性症在两性中逐渐变得同样普遍的假设。1994年后性别比例的下降，要么可以解释为男变女变性者积压人数的减少，要么可以解释为治疗方面的最新进展以及变性者群体对所提供治疗的看法所导致的人为现象。
