Detailed explanation-1: -The progesterone receptor not only functions using classical nuclear receptor signaling, but also participates in non-genomic signaling at the cellular membrane.

Detailed explanation-2: -Progesterone prepares the endometrium for the potential of pregnancy after ovulation. It triggers the lining to thicken to accept a fertilized egg. It also prohibits the muscle contractions in the uterus that would cause the body to reject an egg.

Detailed explanation-3: -The major metabolic pathway of progesterone is reduction by 5-reductase and 5-reductase into the dihydrogenated 5-dihydroprogesterone and 5-dihydroprogesterone, respectively.

Detailed explanation-4: -A protein found inside the cells of the female reproductive tissue, some other types of tissue, and some cancer cells. The hormone progesterone will bind to the receptors inside the cells and may cause the cells to grow.
