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.

优势卵泡的筛选大概要经历一周；优势卵泡后，其余的卵泡就会退化闭锁。

The follicles respond by pumping out estrogen.

卵泡的成熟，会进一步促进雌性的分泌。

Progesterone is produced by the empty follicle in the ovary.

黄体酮是由卵巢中的空卵泡产生的。

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，也就是试管受精的女性，我们也观察了她们的卵泡--即提取卵子时得到的卵子周围的体。

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，当男性处于女性月经周期的卵泡期时，他们对女性更有吸引力，而且他们的睾丸水平处于最高。

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的促卵泡（FSH）和黄体生成（LH），因为这些会刺卵巢分泌雌。

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.

另一个周期，卵巢周期，是关于卵泡和卵子的成熟，这实际上是驱动月经周期的原因。

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

生育专家将卵泡刺的数值作为重要指标来衡量女性体内卵子数量，数值高则卵子数量少。

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

卵泡是由颗粒细胞、卵泡膜细胞组成的小簇，保护发育中的卵细胞。

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.

卵泡刺通过触发卵泡自身分泌雌来驱动幸运的卵泡继续生长，雌在局部发出信号，使卵泡更加成熟。

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.

格拉夫卵泡的中间会形成一个空腔叫做卵泡腔，而颗粒细胞会为初级卵母细胞分泌营养，直接排入卵泡腔。

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

每次月经周期的卵泡期，少数生长迅速的格拉夫卵泡，会进入成熟的第三个阶段。

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

青春期开始后，卵巢的卵泡膜细胞对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.

卵泡刺由体内产生，以刺卵巢中的卵泡产生卵子。

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

然后雌会阻止卵泡刺的产生，这样在一个周期内只有一个卵子成熟。

These hormones travel to the follicles within the ovaries.

这些最终进入卵巢内的卵泡中。

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 开始作用于卵泡内休眠的卵母细胞，并触发它最终再次开始分裂——让它完成减数分裂 I 并进入中期 II。

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

月经后，子宫内膜再次增厚，为受精卵做准备，卵巢内的卵泡发育。

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.

少数幸运的初级卵泡可以随着青春期第一次月经周期进入第二阶段，还有更多的卵泡也幸运地随着，接下来的月经周期进入第二阶段。

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.

促卵泡通过刺卵泡的生长名副其实——但只有一个：那个时候发育得最远的卵泡。
