Webwait in this video he mentioned estrogen is being produced as a result of FSH secretion from posterior pituitary but in previous videos he said that LH effects on theca cells results in production of androstenedione which leads to granulosa cells producing estrogen. So which one is it? Theca cells are responsible for synthesizing androgens, providing signal transduction between granulosa cells and oocytes during development by the establishment of a vascular system, providing nutrients, and providing structure and support to the follicle as it matures. Theca cells are responsible for the production of androstenedione, and indirectly the production of 17β estradiol, also called E2, by supplying the neighboring granulosa cells with androstenedione t…
