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.
In any case, the ovaries fail to respond to pituitary LH and FSH and which means that they don't release egg cells normally and produce less estrogen, progesterone, and androstenedione.
The androgens include testosterone, which is produced by the testicles, androstenedione and dehydroepiandrosterone which are produced by the adrenal glands, and dihydrotestosterone, which is made from testosterone by the prostate itself.
The result is the ovaries fail to respond to pituitary LH and FSH, which means that they don't ovulate or release egg cells normally and they produce less estrogen, progesterone and androstenedione.
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.
