Aromatase is key to Estradiol production in the ovaries. Which of the following statements is true
FSH induces the granulosa cells to produce aromatase for this purpose
It is important to have a good understanding of the two main cell types of the ovaries.
The theca cells produce androgen in the form of androstenedione.The theca cells are not able to convert androgen to estradiol themselves. The produced androgen is therefore taken up by granulosa cells.
The neighbouring granulosa cells then convert the androgen into estradiol under the enzymatic action of aromatase
FSH induces the granulosa cells to produce aromatase for this purpose
