Vasopressin concentrations were measured in the cerebrospinal fluid in two hydrocephalic fetuses at 33 and 34 weeks of gestation. The vasopressin concentrations in cerebrospinal fluid were 0.8 and 0.6 pg/ml, and in amniotic fluid 0.4 and 1.0 pg/ml, respectively. Previously measured vasopressin concentrations in amniotic fluid of the normal fetuses have been of the same magnitude.
