Constriction of the fetal ductus arteriosus by progesterone
Biology of the Neonate
|January 1, 1986
Abstract:
Progesterone substitution in the rat during pregnancy days 17-21 or administration 6 h before spontaneous delivery constricted the fetal ductus arteriosus. The rapid whole-body freezing technique was used. Indomethacin-induced constriction of the fetal ductus arteriosus was not affected by progesterone treatment.
