Abstract

The maternofetal transfer of I¹³¹-labeled human insulin was studied in 9 women undergoing caesarean section. The data suggest that insulin readily traverses the human placenta and that the amount transferred from mother to fetus is equivalent to 33% of the insulin utilized by the normal fetus at term and this amount is also equal to 33% of the insulin synthesized by the normal fetus at term. The placenta appears to be equally permeable in the direction of fetus to mother.
