Peculiarities of placental hormonal function of primaparae of different age with threat of abortion

Content of estriol, progesterone, and placental lactogen (PL) was studied in dynamics of gestation. Diverse levels of these hormones are ascribed to fetoplacental insufficiency and abnormalities of placental hormonal function that brings about the necessity of timely proper therapy.
