33 measurements of urinary estriol from 30-40 weeks' gestation in 22 pregnancies where dysmaturity was diagnosed in utero are shown graphically. The mean estriol excretion was about 2-3 mg below the lower limit of normal; it increased more slowly with gestational age: and it declined precipitously from 34-38 weeks. 1/3 of the women delivered at 38 weeks, either spontaneously or by induction. The mean estriol curve in the remaining women rose during treatment until delivery at 40 weeks. No correlation could be discerned in individual cases between the estriol excretion curve (or especially between an individual estriol value) and fetal weight, maturity, fetal distress in labor, or fetal death (1 case).
