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

LH与卵泡内膜细胞上的LH受体结合，产生黄体酮和雄烯二酮。

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.

这包括卵泡刺激素（FSH）、促黄体生成素（LH）。

Both FSH and LH are secreted by the pituitary gland.

FSH 和 LH 都是由垂体分泌的。

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

黄体生成素使成熟的卵子从卵巢中释放出来，并刺激黄体酮的释放。

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——促卵泡激素（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，残余的卵巢滤泡，称为黄体，分泌孕激素，通过负反馈作用抑制垂体分泌LH。

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

伴随着卵细胞的成长，雌性激素的分泌也将达到峰值，同时抑制促卵泡激素，促进垂体释放更多的黄体化激素。

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的内膜细胞生成更多黄体酮。

ICSH is the male equivalent of LH.

ICSH又被称为LH。

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

没有卵巢滤泡意味着没有雌激素和孕激素，这导致FSH和LH水平处于高位。

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

没有了FSH的刺激，雌激素水平开始降低，LH的水平也会回到排卵前。

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卵，因此孕激素水平升高不足，没能抑制LH的产生。

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

这会导致低水平的血清雌激素以及高水平FSH和LH。

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的作用，它会使垂体FSH和LH的分泌减少。

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

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

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卵巢综合征的病因，但似乎是LH和FSH之间的平衡被打破了。

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 的存在—— 这个区域的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.

下丘脑分泌促性腺激素释放激素，即GnRH，刺激临近的垂体前叶释放卵泡刺激素（FSH）和黄体生成素（LH）。
