title: Effect of intrauterine death and fetectomy on ovine placental lactogen production.
abstract: Concentrations of ovine placental lactogen (oPL) were measured in the peripheral plasma of six ewes after the removal of fetuses (in four ewes) or after the intrauterine death of one of twin fetuses (in two ewes). Concentrations of oPL decreased after fetectomy or intrauterine fetal death, indicating that a living fetus is essential to the sustained secretion of oPL.
