2.7 Progesterone

2.7.1 Site of production of progesterone

Above: Magnified view of the ovary to show how corpus luteum is formed. After the Graafian follicle has released the mature ovum, the remains of the Graafian follicle form the corpus luteum.

• Progesterone is produced by the corpus luteum found at the ovary.

2.7.2 Effects of progesterone

1. Progesterone maintains the thickness of the uterine lining.

2. Progesterone inhibits FSH production and therefore development of more follicles at the ovary.
