  • Description

    Progesterone (P4, pregn-4-ene-3,20-dione) belongs to a class of hormones called progestogens, and is an essential regulator of female reproductive function in the uterus, ovary, mammary gland and brain. Progestogens are the primary hormones involved in the female menstrual cycle, gestation, and embryogenesis of humans and most other species. Progesterone can be metabolized and excreted as a variety of general progesterone by-products. Common metabolites include 5-reduced progesterone (pregnane), pregnanolones and hydroxyprogesterones. Measurement of progesterone metabolites provides vital data about reproductive status and is essential for studying reproductive and survival strategies of wildlife and endangered species. Likewise, assays measuring progesterone metabolites provide a clearer picture of hormonal regulation and reproduction.
