WebAug 26, 2024 · Before ovulation, granulosa and theca cells in the follicle produce estrogen. However, after ovulation, LH triggers these cells to transform. They begin to release the hormone progesterone. Progesterone plays an important role in the luteal phase. First, progesterone signals the pituitary and hypothalamus glands in the brain to slow … WebTheca and granulosa cell cooperation in estrogen synthesis. Theca cells produce androgens in response to luteinizing hormone (LH). Granulosa cells respond to follicle-stimulating hormone (FSH) mainly by aromatizing androgens to estrogens and to some extent by producing pregnenolone from cholesterol. fossil boots zapposTheca 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.
