17 beta-estradiol (E2) and estriol-16-glucuronide in amniotic fluid from 87 patients (normal and stressed pregnancies) were studied with radioimmunoassays. Overall, amniotic fluid estradiol and estriol increased with gestation and paralleled the increase in the L/S ratio. Statistical correlations between amniotic
