title: [Half-life of dehydroepiandrosterone sulfate (DHAS) during pregnancy].
abstract: During pregnancy the half-life of DHAS was measured after non tritiated DHAS infusion. At 30 weeks, the mean value obtained for DHAS half-life was 3.64 h +/- 0.74 and it was 3.67h +/- 0.38 at 38 weeks. The half-life of DHAS is shorter in pregnant than in non-pregnant women. Among 14 pathological pregnancies that we studied, 13 cases exhibited a DHAS half-life significantly longer than the average value obtained in normal pregnancies. In retarded fetal growth, the half-life of DHAS was more closely related to fetal than to placental weight.
