Abstract

The aim of the present study was to investigate the effect of oxytocin (OT) on progesterone secretion by bovine corpus luteum (CL) in different culture systems. When luteal cells were cultured for 1, 2, 4 and 15 h at a density of 6 × 104 cells/ml, OT (107 M) did not affect progesterone secretion. On the other hand, bovine LH strongly stimulated progesterone secretion by the cells 215 h after incubation (P-7 M). Slices were replaced every 1 h in a fresh medium during the 5 h incubation experiment. A 1-h stimulation with bovine LH and OT induced significant but different effects on the release of progesterone. OT acutely stimulated progesterone release at doses 10~7 M (155%; P
