The last kind of functional cysts are theca lutein cysts.

最后一种功能，是卵泡膜黄素。

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，产生黄体酮和雄烯二酮。

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

在女中，卵泡膜细对黄体生成素产生反应，从而产生孕酮和雄烯二酮。

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。

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生成更多黄体酮。

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产生应答，生成孕酮和雄烯二酮。

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.

每个卵泡最初是由未成熟的生殖细：初级卵母细（即女生殖细）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，使卵泡生长成熟，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。
