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平下降，如性腺功能减退，会导致勃起功能障碍。

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

可引起原发性性腺功能减退症性因有放疗、化疗和性腺创伤。

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

可引起原发性性腺功能减退先天因包括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生性，导致性腺功能低下、雌平低。

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

有些性因与原发性性腺功能减退症相似，也包括放疗、化疗和性腺创伤。

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

正因如此，Kallmann合征是一种低促性腺性性腺功能减退症。

There are two main causes of hypogonadism.

性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.

血液平检测可以为性腺功能减退类型提供参考。

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

Kallmann合征是一种低促性腺性性腺功能减退症，其嗅觉神经元与促性腺释放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).

由于促性腺平高，而性腺或卵巢平低，这被称为高促性腺型性腺功能减退症。

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，所以原发性性腺功能减退症也称为高促性腺性性腺功能减退症。

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.

尽管青春期延迟病因很多，会导致促性腺平各不相同，但最终结果都是性腺功能减退以及男性睾酮或女性雌和孕酮缺乏。

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.

与继发性性腺功能减退症类似，也存在GnRH缺乏，但关键区别在于这种缺乏不是病理性，而是一种正常发育延迟。

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.

继发性性腺功能减退症可由下丘脑或垂体功能障碍导致，既可能是促性腺释放、黄体生成和卵泡刺生成能力低下，也可能是以上分泌受到了其他抑制，例如泌乳或甲状腺。

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.

性腺功能减退第二个病因是继发性性腺功能减退症，也称为低促性腺性性腺功能减退症，因为LH和FSH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.

一是原发性性腺功能减退，由性腺功能障碍引起，例如，性腺受体对促性腺不敏感或者性腺内没有能够产生性健康细胞。
