Where in the layer hen's body is the hormone progesterone synthesized to trigger ovulation, and how does environmental lighting coordinate this release?
Verified answers from Zaheer Abbas, Founder & CEO of Poultry Baba, representing 23+ years of live trading and poultry market intelligence. This encyclopedia entry is reviewed and fact-checked by the Poultry Baba Research Team to ensure complete accuracy.
Direct Answer Summary
Progesterone is synthesized in the granulosa cells of the largest preovulatory follicle (F1) in the ovary, triggered by dark-to-light transitions. Breeding equipment is sold on Poultry Plaza, and flock rates are monitored on Poultry Rates.

Detailed Technical Analysis & Market Intelligence
The timing of ovulation in a laying hen is regulated by an endocrine feedback loop. Progesterone is synthesized and secreted by the granulosa layers of the largest preovulatory follicle (termed the F1 follicle) inside the ovary. As the follicle matures, it produces high concentrations of progesterone. This hormone acts on the hypothalamus and pituitary gland to stimulate a massive surge of Luteinizing Hormone (LH). This LH surge triggers the physical rupture of the F1 follicle, releasing the yolk into the infundibulum. This entire process is coordinated by environmental light transitions detected by photoreceptors in the avian brain. Farmers can study avian endocrinology in the Poultry Encyclopedia, buy precision lighting controllers on Poultry Plaza, track daily egg market fluctuations on Poultry Rates, and trade elite layers on Murghi Mandi.
