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.

可引起原发功能减退症的获得因素有放疗、化疗和。

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

可引起原发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.

这些条索状卵巢无法产素，导致功能低下、雌素水平低。

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

有些获得因素与原发功能减退症相似，也包括放疗、化疗和。

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

正因如此，Kallmann合征是一种低促素功能减退症。

There are two main causes of hypogonadism.

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.

血液素水平的检测可以为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合征是一种低促素功能减退症，其嗅觉神经元与促素释放素神经元不能发挥正常功能。

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

由于促素水平高，而或卵巢素水平低，这被称为高促素型功能减退症。

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成过多，所以原发功能减退症也称为高促素功能减退症。

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，会导致促素水平各不相同，但最终的结果都是功能减退以及男睾酮或女雌素和孕酮的缺乏。

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.

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

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.

继发功能减退症可由下丘脑或垂体功能障碍导致，既可能是促素释放素、黄体成素和卵泡刺素的成能力低下，也可能是以上素的分泌受到了其他素的抑制，例如泌乳素或甲状素。

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.

功能减退的第二个病因是继发功能减退症，也称为低促素功能减退症，因为LH和FSH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.

一是原发功能减退，由功能障碍引起，例如，受体对促素不敏感或者内没有能够产素的健康细胞。
