LH binds to LH receptors on theca cells and they make progesterone and androstenedione.

LH与内膜细胞上LH受体结合，生黄体酮和雄烯二酮。

Both FSH and LH are secreted by the pituitary gland.

FSH 和 LH 都是由垂体分。

So notice RH: right hand, LH: left hand.

所以注意”RH“代表右手，”LH“代表左手。

These are follicle stimulating hormone, or FSH, and luteinizing hormone, or LH.

这包括刺激素（FSH）、黄体生成素（LH）。

Specifically, ovulation doesn't occur, so progesterone levels don't rise enough to inhibit LH production.

具体来说就是没有发生排，因此孕激素水平升高不足，没能抑制LH生。

No ovarian follicles also means no estrogen and progesterone, which leads to high levels of FSH and LH.

没有巢滤意味着没有雌激素和孕激素，这导致FSH和LH水平处于高位。

This leads to low serum estrogen and high FSH and LH.

这会导致低水平血清雌激素以及高水平FSH和LH。

There are two other hormones also involved — the follicle-stimulating hormone, or FSH, and the luteinizing hormone, or LH.

另外还有两种激素——激素（FSH）和黄体生成素（LH）。

During the luteal phase, the remnant of the ovarian follicle, called the corpus luteum, makes progesterone, which negatively inhibits pituitary LH.

在黄体期，残余巢滤，称为黄体，分孕激素，通过负反馈作用抑制垂体分LH。

LH causes the mature egg to be released from the ovary and stimulates the release of progesterone.

黄体生成素使成熟子从巢中释放出来，并刺激黄体酮释放。

The egg cells grow and estrogen levels peak, inhibiting the production of FSH, and telling the pituitary to pump out more LH.

伴随着细胞成长，雌性激素分也将达到峰值，同时抑制激素，进垂体释放更多黄体化激素。

If that's negative, diagnosis requires serum levels of FSH, LH, estrogen, prolactin, TSH and testosterone.

如果没有怀孕，需要检测血清中FSH、LH、雌激素、乳素、TSH和睾酮水平以进行诊断。

Lufthansa Flight LH 203 leaves at 0920.

--汉莎航空 LH 203 航班于 0920 起飞。

Luteinized theca cells respond to the low LH concentrations after ovulation by producing more progesterone.

LH水平降低会使黄素化内膜细胞生成更多黄体酮。

ICSH is the male equivalent of LH.

ICSH又被称为LH。

Now, it's not clear exactly what causes PCOS, but there seems to be an imbalance between LH and FSH levels.

我们现在还不清楚多囊巢综合征病因，但似乎是LH和FSH之间平衡被打破了。

Without FSH, estrogen levels fall, and the amount of LH goes back to the level before ovulation.

没有了FSH刺激，雌激素水平开始降低，LH水平也会回到排前。

However, estrogen acts a negative feedback signal – that is, it tells the pituitary to secrete less FSH and LH.

但是雌激素却会起负反馈作用，它会使垂体FSH和LH分减少。

Scientists knew that the LH-VTA Loop existed -- problems in this area have been linked to some sexual and drug addictions.

科学家们知道 LH- VTA Loop 存在—— 这个区域问题与一些性瘾和毒瘾有关。

The hypothalamus secretes gonadotropin-releasing hormone, or GnRH, which makes the nearby anterior pituitary gland release follicle-stimulating hormone, or FSH, and luteinizing hormone, or LH.

下丘脑分性腺激素释放激素，即GnRH，刺激临近垂体前叶释放刺激素（FSH）和黄体生成素（LH）。
