Summary The pathways of water exchange between liquor amnii and the fetoplacental unit were examined in vivo in pregnancies of 14 to 22 weeks’gestation. Fetal skin permeability appears to decrease with increasing fetal size while the umbilical cord becomes an increasingly important site from 18 weeks. The fetal surface of the placenta appears to be important as a site of water exchange.
