除了染色体和激素的病因以外，环境因素也可能卷入了中间性综合征的发生过程。在胎儿出生之前，放射线、化合物和某些药物能够对胎儿的发育产生负面影响。可是，这些环境因素如何精确地产生负面影响和它们在导致疾病方面怎样扩展它们的作用，总也没有完全弄清楚。在有一些病例，它们的负面影响已经被证实，而在其他的病例仅仅是怀疑它们有负面作用。不过，环境因素现在正在增加研究者们对中间性的研究兴趣。我们已经知道放射线能够影响染色体，也已经知道某些化合物能够扰乱身体激素的自主平衡，我们还知道某些药物能够导致在孩子出生前后的非常严重的体格发育问题。

Causes of Intersexuality - Environment

In addition to chromosomal and hormonal causes, there may also be environmental factors involved in producing intersexual conditions.
Radiation, chemicals, and certain medications can negatively influence the growth of a fetus before birth. It is not always known, however, how exactly these factors work and how extensive a role they really play. In some cases, their influences are proven, in others merely suspected. However, they are now of increasing interest to researchers studying intersexuality. We know that radiation can affect the chromosomes, that some chemicals can disturb the natural balance of hormones, and that certain medications can cause very serious physical problems before and after birth.
