Molecular Structure

About

Progesterone, also known as P4, is an endogenous steroid hormone, produced by the corpus luteum. It belongs to a group of steroid hormones called the progestogens, and is the major progestogen in the body. Progesterone is also a crucial metabolic intermediate in the production of other endogenous steroids, and plays an important role in brain function as a neurosteroid.
