Chemical Information
FooDB Name20alpha-Dihydroprogesterone
DescriptionA biologically active 20-alpha-reduced metabolite of progesterone. It is converted from progesterone to 20-alpha-hydroxypregn-4-en-3-one by the 20-alpha-hydroxysteroid dehydrogenase in the corpus luteum and the placenta. -- Pubchem; Progesterone is a C-21 steroid hormone involved in the female menstrual cycle, pregnancy (supports gestation) and embryogenesis of humans and other species. Progesterone belongs to a class of hormones called progestagens, and is the major naturally occurring human progestagen. -- Wikipedia; During implantation and gestation, progesterone appears to decrease the maternal immune response to allow for the acceptance of the pregnancy. Progesterone decreases contractility of the uterine smooth muscle. The fetus metabolizes placental progesterone in the production of adrenal mineralo- and glucosteroids. A drop in progesterone levels is possibly one step that facilitates the onset of labor. In addition progesterone inhibits lactation during pregnancy. The fall in progesterone levels following delivery is one of the triggers for milk production. -- Wikipedia [HMDB]
