It usually takes about a week for a dominant follicle to get selected, and after that happens, the rest of the follicles regress and die off.

优势泡筛选大概要经历一周；优势泡被募集后，其余泡就会退化闭锁。

The follicles respond by pumping out estrogen.

泡成熟，会进一步促进雌性激素分泌。

Progesterone is produced by the empty follicle in the ovary.

黄体酮是由巢中空泡产生。

And these are women who are undergoing in vitro fertilization, IVF, so we're also looking at their follicular fluid-so the fluid around the eggs that we get at the time of the egg retrieval.

这些是正在接受体外受精，也就是试管受精女性，我们也观察了她们泡--即提取子时得到子周围体。

There is some evidence that men are more attractive to women when they are in the follicular phase of their menstrual cycle, and their testosterone levels are at their highest.

有一些证据表明，当男性处于女性经周泡时，他们对女性更有吸引力，而且他们睾丸激素水平处于最高。

The body will respond by producing more follicle-stimulating hormone (FSH) and luteinizing hormone (LH) than normal, since these hormones stimulate estrogen secretion by the ovaries.

人体会产生比正常人更多促泡激素（FSH）和黄体生成素（LH），因为这些激素会刺激巢分泌雌激素。

The other cycle, the ovarian cycle, is all about the maturation of the follicle and egg, and it's actually what drives the menstrual cycle.

另一个周，巢周，是关于泡和子成熟，这实际上是驱动经周原因。

Fertility experts regard a high FSH level as a key indicator of having a low egg count.

生育专家将泡刺激素数值作为重要指标来衡量女性体内子数量，数值高则子数量少。

The follicles are small clusters of granulosa and theca cells that protect the developing egg cell.

泡是由颗粒细胞、泡膜细胞组成小簇，保护发育中细胞。

The FSH drives that one lucky follicle to keep growing, by triggering the follicle itself to secrete its own estrogen hormones, which locally signal the follicle to mature even more.

泡刺激素通过触发泡自身分泌雌激素来驱动幸运泡继续生长，雌激素激素在局部发出信号，使泡更加成熟。

In a graafian follicle, a central cavity called the antrum forms within the follicle, and the granulosa cells secrete a nourishing fluid for the primary oocyte directly into that antrum.

格拉夫泡中间会形成一个空腔叫做泡腔，而颗粒细胞会为初级母细胞分泌营养，直接排入泡腔。

During the follicular phase of each menstrual cycle, the few fast-growing graafian follicles enter the third stage of development.

每次经周泡，少数生长迅速格拉夫泡，会进入成熟第三个阶段。

Beginning at puberty, the theca cells of the ovary respond to luteinizing hormone by producing progesterone and androstenedione.

青春开始后，巢泡膜细胞对LH产生应答，生成孕酮和雄烯二酮。

FSH is produced by the body to stimulate the follicles in the ovaries that produce eggs.

泡刺激素由体内产生，以刺激巢中泡产生子。

The estrogen then stops FSH being produced, so that only one egg matures in the cycle.

然后雌激素会阻止泡刺激素产生，这样在一个周内只有一个子成熟。

These hormones travel to the follicles within the ovaries.

这些激素最终进入巢内泡中。

The LH gets to work on the oocyte that's been dormant inside the follicle, and triggers it to finally start dividing again — getting it to complete meiosis I and move on to metaphase II.

LH 开始作用于泡内休眠母细胞，并触发它最终再次开始分裂——让它完成减数分裂 I 并进入中 II。

After menstruation, the lining of the uterus thickens up again in preparation for a fertilized egg, and inside the ovary follicle develops.

经后，子宫内膜再次增厚，为受精做准备，巢内泡发育。

The second stage of follicular development begins for a few lucky primary follicles with the first menstrual cycle in puberty, and a few more primary follicles go into the second stage with each subsequent menstrual cycle.

少数幸运初级泡可以随着青春第一次经周进入第二阶段，还有更多泡也幸运地随着，接下来经周进入第二阶段。

The follicle-stimulating hormone lives up to its name by stimulating the growth of a follicle — but only one: the one that happens to be furthest along in development at the time.

促泡激素通过刺激泡生长名副其实——但只有一个：那个时候发育得最远泡。
