中间性 - 中间性性象谱

中间性的原因 - 激素因素

大量中间性的病例可以追溯到激素的致病原因。就是说，在个体出生之前，某种激素缺乏或激素活性降低，因此胎儿向男性方向正常发育未完成。其结果是内部性器官和外部性器官在形态上有一定程度的含混不清，并且也有一般体格外貌的改变。同理，我们在此不可能详细讨论宽泛的中间性的各种性象谱。不过，以下描述的内容，一般说来是一些最重要的病症，它们是：

• 男性性激素失敏性综合征 (AIS)
• 5-α-还原酶缺乏 (5-ARD)
• 先天性肾上腺增生性肥大 (CAH)

Intersexuality - The Intersexual Spectrum

Causes of Intersexuality - Hormones

A number of intersex conditions can be traced to hormonal causes. That is to say, before birth, certain hormones are deficient or their activity is impaired, and thus the typical development of the fetus toward maleness remains incomplete. The result is some ambiguity in the formation of the internal and external sex organs and sometimes also in the person’s general physical appeareance. Again, there is a wide spectrum of possibilities that cannot be discussed in detail in this course. However, the following sections describe, in a general way, the most important of the conditions. They are

• Androgen Insensitivity Syndrome (AIS)
• 5-Alpha-Reductase Deficiency (5-ARD)
• Congenital Adrenal Hyperplasia (CAH)
