The last kind of functional cysts are theca lutein cysts.

最后一种功能性囊肿，是卵泡膜黄素囊肿。

In females, the theca cells respond to luteinizing hormone by producing progesterone and androstenedione.

在女性中，卵泡膜细对促黄体成素应，从而孕酮和雄烯二酮。

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成多黄体酮。

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

卵泡是由颗粒细、卵泡膜细组成的小簇，保护发育中的卵细。

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

LH与卵泡内膜细上的LH受体结合，黄体酮和雄烯二酮。

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

青春期开始后，卵巢的卵泡膜细对LH应答，成孕酮和雄烯二酮。

Theca cells make androstenedione, a sex hormone precursor, and granulosa cells use the enzyme aromatase to convert it into estradiol - a member of the estrogen family.

卵泡内膜细可以合成雄烯二酮，是性激素的前体；颗粒细的芳香酶使它变成雌二醇，是雌激素的一种。

Each follicle is initially made up of an immature sex cell, or primary oocyte, which is the female sex cell, and layers of theca and granulosa cells surrounding the oocyte.

初级卵母细（即女性殖细）和卵母细外层的鞘细、颗粒细组成。

Right after ovulation, while the LH levels are still high, the remains of the follicle turn into the corpus luteum, which is made up of luteinized granulosa and theca cells.

排卵之后，LH水平依然很高，卵泡剩下的部分，即被黄素化的颗粒细和内膜细就会组成黄体。

In a secondary follicle, the primary oocyte is still in the prophase step of meiosis 1, but now the follicle has additional layers of granulosa cells, as well as theca cells.

次级卵泡中的初级卵母细还是停留在第一次减数分裂前期，而卵泡多了几层颗粒细，以及卵泡内膜细。

FSH acts on the granulosa cells, making the follicles grow and mature, as well as secrete estrogen while LH stimulates theca cells to secrete progesterone and small amounts of androstenedione, which is a precursor of testosterone.

FSH作用于颗粒细，使卵泡长成熟，以及分泌雌激素；而LH刺激卵泡膜细分泌孕激素与少量雄烯二酮，后者是睾酮的前体。

Theca lutein cysts are more likely to develop when there’s more hCG than usual, like when there are multiple fetuses, or with gestational trophoblastic disease, where tumours made up of placental cells causes higher than normal hCG levels.

卵泡膜黄素囊肿一般发于hCG较正常高的情况，如多胎妊娠或患有妊娠滋养细疾病时；该病中由胎盘细组成的肿瘤会导致hCG较高。
