title: Biosynthesis, metabolism and regulation of steroid hormones secretion in the placental phase of gestation in the rat.
abstract: The regulation of biosynthesis of steroid hormones in the pre-placental stage and in placental phase of pregnancy in the rat is described. On the ground of our own studies a concept of an ovarian-placental unit in the rat has been formulated. This unit is characterized by coupled biosynthesis and secretion of steroid hormones in the placental stage of rat pregnancy.
