How Glandular structure produces progesterone?

Progesterone is primarily produced by the corpus luteum in the ovaries after ovulation. The glandular structure of the corpus luteum consists of luteal cells that secrete progesterone in response to luteinizing hormone (LH) signals from the pituitary gland. These cells synthesize progesterone from cholesterol through a series of enzymatic reactions, facilitating the preparation of the uterine lining for potential implantation of a fertilized egg. If pregnancy does not occur, the corpus luteum degenerates, leading to decreased progesterone levels.
