Periodic collections of uterine venous blood were obtained from three nonmated, three pregnant and two mated but nonpregnant ewes in which uterine veins were cannulated with polyvinyl tubing on day 11 postestrus. Frequent sampling was achieved in three of these ewes with additional cannulae in the ovarian veins. Blood samples were collected at 3-hr intervals from 0600 on day 12 to 1800 on day 13 and then 6-hr intervals through day 15. On day 13, three additional samples at 30-min intervals were collected between 1400 and 1530. Prostaglandins F (PGF) in plasma were quantified by radioimmunoassay. On day 12, one ewe in each group had at least one measurement which suggested an increased rate of release of PGF into the uterine vein. Seven of eight ewes on day 13 appeared to have increased rates of release of PGF from the uterus between 0900 and 1500. The highest level measured in each ewe during this period ranged from 2.7 to 11 ng per milliliter. Concentrations of PGF in ovarian venous plasma in two of three ewes were positively correlated (P less than .05) with concentrations of PGF in uterine venous plasma (r equals .64 in each ewe). No evidence was obtained that pregnant and nonpregnant ewes differ in rate or pattern of release of PGF from the uterus into the uterine vein on days 12 and 13. Comparisons could not be made with confidence concerning PGF either in uterine veins on days 14 and 15 or in ovarian veins on all days due to limited number of observations.
