Conteúdo: | Abstract: Patterns of variation in progestin concentrations were studied in pregnant sheep during the last half of gestation. In three sets of experiments, blood was drawn daily or every 4 h for 24 h or every 10 min for 8 h. Peripheral arterial concentration of progestin was examined for 'peaks' using the Pulsar program which identified peaks in daily samples and in samples collected every 10 min, though less often than in daily samples. Ovariectomy did not affect the frequency or character of the peaks. The data suggest that large variations in progestin concentrations occur during the last half of pregnancy. They are superimposed on a gradual increase in average concentration and last for 2 to 3 days.
