  • Title: Glucocorticoid metabolism in human placenta, decidua, myometrium and fetal membranes.
    Author: Giannopoulos G, Jackson K, Tulchinsky D.
    Journal: J Steroid Biochem; 1982 Oct; 17(4):371-4. PubMed ID: 7132352.
    Abstract:
    The metabolism of cortisone (E) and cortisol (F) by human placenta, decidua, myometrium, chorion and amnion during pregnancy was studied in vitro. Early pregnancy, midpregnancy and term placentae metabolized F efficiently yielding E as the major product. The capacity of the placenta to inactivate F to E was observed as early as the 8th week of pregnancy and there was a significantly higher (P less than 0.001) net production of E in early pregnancy placenta than in term placenta. In contrast to the placenta, midpregnancy and term decidua metabolized mainly E to F with a net production of F. Term chorion demonstrated an equal degree of oxidative and reductive glucocorticoid metabolism while term amnion and myometrium had negligible metabolic activity. Thus the net production of F from E by the decidual membrane unit is due to metabolic activity in the decidua as early as the 13th week of pregnancy and not to activity in the fetal membranes.
