FSH binds to FSH receptors on granulosa cells and they make aromatase and, as a consequence, estrogen.

FSH和颗粒细胞上FSH受体结合，产生芳香酶，进而产生雌激素。

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.

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

In addition to estrogen, the granulosa cells also secrete a hormone called activin, which stimulates FSH production, as well as binding to FSH receptors, and the activity of granulosa cell aromatase as well.

除了雌激素，颗粒细胞还会分泌一种激素叫做激活素，它可以刺激FSH的分泌，与FSH受体结合；并且与颗粒细胞芳香酶的活性有关。
