Product Description
Progesterone is a steroid hormone that regulates the menstrual cycle and is crucial for pregnancy.
Progesterone (abbreviated as P4), also known as pregn-4-ene-3,20-dione,is an endogenous steroid and progestogen sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species.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, including the sex hormones and the corticosteroids, and plays an important role in brain function as a neurosteroid.

The use of progesterone and its analogues have many medical applications, both to address acute situations and to address the long-term decline of natural progesterone levels. Because of the poor bioavailability of progesterone when taken orally, many synthetic progestins have been designed with improved oral bioavailability and have been used long before progesterone formulations became available.
