The last kind of functional cysts are theca lutein cysts.

最后一种功能性囊肿，是泡膜素囊肿。

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

在女性中，泡膜细胞对促成素产反应，从而产孕酮和雄烯二酮。

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

LH水平降低会使素化的内膜细胞成多酮。

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

泡是由颗粒细胞、泡膜细胞组成的小簇，保护发育中的细胞。

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

LH泡内膜细胞上的LH受结合，产酮和雄烯二酮。

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

青春期开始后，巢的泡膜细胞对LH产应答，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.

泡内膜细胞可以合成雄烯二酮，是性激素的前；颗粒细胞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.

初级母细胞（即女性殖细胞）和母细胞外层的鞘细胞、颗粒细胞组成。

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.

排之后，LH水平依然很高，泡剩下的部分，即被素化的颗粒细胞和内膜细胞就会组成。

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.

次级泡中的初级母细胞还是停留在第一次减数分裂前期，而泡多了几层颗粒细胞，以及泡内膜细胞。

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作用于颗粒细胞，使泡长成熟，以及分泌雌激素；而LH刺激泡膜细胞分泌孕激素少量雄烯二酮，后者是睾酮的前。

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.

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