SONAR IN EARLY PREGNANCY [PDF]
Journal of Perinatal Medicine, 1981 Prior to the existence of sonar techniques there was no method to proof the existence of a l iving fetus early in pregnancy. Hormon assays such as human chorionic gondotropin, human placental lactogen oestriol and pregnandiol could offer only indirect informations relating to the trophoblast and corpus luteum function. Concerning the fetus there was no
