Theca interna cells express receptors for luteinizing hormone to produce androstenedione, which via a few steps, gives the granulosa the precursor for estrogen manufacturing.
After rupture of the mature ovarian follicle, the theca interna cells differentiate into the theca lutein cells of the corpus luteum. These cells secrete estradiol.
