中间性 - 中间性性象谱

中间性的原因

正如我们已经了解的那样，在男性与女性之间存在着异乎寻常的性象谱。现今，这个男女之间的性象谱由术语“中间性(intersexuality)” 予以标称。 
中间性的各种各样类型和程度差异有数种可能的原因。简要地说来，中间性的各种各样的性象谱可以追溯到三类可能的原因：

1. 染色体的因素，
2. 激素的因素，
3. 环境的因素。

在中间性所有案例中，约有25%未能精确地做出诊断，其导致的原因仍不清楚。

我们的基本教程不可能涵盖可追溯到不同原因的所有的中间性。不过，下述的内容至少可以对那些已经研究透了的中间性作一些基本的介绍。

Intersexuality - The Intersexual Spectrum

Causes of Intersexuality

As we have seen, there is a spectrum of atypical conditions between femaleness and maleness. Today, many of them are covered by the term “intersexuality”.
There are several possible causes for the various forms and degrees of intersexuality. Briefly summarized, they can be traced to three kinds of possible sources:

1. Chromosomal,
2. hormonal,
3. environmental.

In ca. 25% of all cases, there is no exact diagnosis, and the cause remains unknown.

The present basic course cannot cover all intersexual conditions traceable to the different sources. Still, the following sections provide at least some general information on the best known forms of intersexuality.
