Next, endocrine dysfunctions that causes testosterone levels to fall, like hypogonadism, can cause erectile dysfunction.

其次，内分泌功能障碍导致睾酮水平下降，如腺功能减退，会导致勃起功能障碍。

Some acquired causes of primary hypogonadism are radiation therapy, chemotherapy, and trauma to the gonads.

可引起原腺功能减退症的因素有放疗、化疗和腺创伤。

Some congenital causes of primary hypogonadism are genetic diseases like Klinefelter or Turner syndrome.

可引起原腺功能减退的先天因素包括Klinefelter合征或Turner合征等遗传病。

These streak ovaries can't produce sex hormones, resulting in hypogonadism and low estrogen levels.

这条索状卵巢无法产生激素，导致腺功能低下、雌激素水平低。

Some acquired causes are similar to primary hypogonadism, radiation therapy, chemotherapy, and trauma to the gonads.

有因素与原腺功能减退症相似，也包括放疗、化疗和腺创伤。

Because of this, Kallmann syndrome is a type of hypogonadotropic hypogonadism disorder.

正因如此，Kallmann合征是一种低促腺激素腺功能减退症。

There are two main causes of hypogonadism.

腺功能减退有两个主要病因。

Blood tests of hormone levels can give an idea of the type of hypogonadism.

血液激素水平的检测可以为腺功能减退的类型提供参考。

So, to recap: Kallmann syndrome is a type of hypogonadotropic hypogonadism where olfactory neurons and gonadotropin-releasing hormone neurons don't function normally.

Kallmann合征是一种低促腺激素腺功能减退症，其嗅觉神经元与促腺激素释放激素神经元不能挥正常功能。

This is called hypergonadotropic (because the level of gonadotropins are high) hypogonadism (because the level of gonad or ovarian hormones is low).

由于促腺激素水平高，而腺或卵巢激素水平低，这被称为高促腺激素型腺功能减退症。

This leads to an overproduction of luteinizing and follicle stimulating hormones, so primary hypogonadism is also called hypergonadotropic hypogonadism.

这会导致LH和FSH生成过多，所以原腺功能减退症也称为高促腺激素腺功能减退症。

Though there are different causes which result in different levels of gonadotropin hormones, they all ultimately result in hypogonadism and a deficiency in testosterone or estrogen and progesterone.

尽管青春期延迟的病因很多，会导致促腺激素水平各不相同，但最终的结果都是腺功能减退以及男睾酮或女雌激素和孕酮的缺乏。

Just like in secondary hypogonadism, there's a lack of gonadotropin-releasing hormone, but the key difference is that it's not considered pathologic - instead, it's thought to be a naturally slowed rate of maturation.

与继腺功能减退症类似，也存在GnRH的缺乏，但关键的区别在于这种缺乏不是病理的，而是一种正常的育延迟。

Secondary hypogonadism can be due to hypothalamus or pituitary gland dysfunction; either from an inability to produce gonadotropin-releasing hormone or luteinizing and follicle stimulating hormones, or suppression from other hormones, like prolactin or thyroid hormone.

继腺功能减退症可由下丘脑或垂体功能障碍导致，既可能是促腺激素释放激素、黄体生成素和卵泡刺激素的生成能力低下，也可能是以上激素的分泌受到了其他激素的抑制，例如泌乳素或甲状腺激素。

The second cause of hypogonadism is secondary hypogonadism, which is also called hypogonadotropic hypogonadism because there are low levels of luteinizing and follicle stimulating hormones.

腺功能减退的第二个病因是继腺功能减退症，也称为低促腺素腺功能减退症，因为LH和FSH激素水平在此病中都显著降低。

The first is primary hypogonadism which is caused by dysfunction of the gonads - for example, the gonad's receptors may not respond to gonadotropin hormones, or the gonads might not have healthy cells that are capable of producing hormone.

一是原腺功能减退，由腺功能障碍引起，例如，腺受体对促腺激素不敏感或者腺内没有能够产生激素的健康细胞。
