The site of placental insertion and fetal growth

A simple method of examining the placenta and its attached membranes after vaginal delivery was used to assess the site of placental insertion in utero. The placental site was determined in 187 term infants. Birth weight and length were not influenced by the position of the placenta, but infants with placentas situated at the fundus had significantly larger heads. Infants with low-lying placentas were at no growth disadvantage.
