Paired bipolar electrodes were implanted in the corpus and uterotubal junctions in pregnant ewes. The temporal changes in uterine myoelectrical activity were monitored in conjunction with maternal and fetal plasma steroid and amniotic fluid electrolytes to evaluate the mechanisms regulating the prepartal uterine contractions in the ewe. Increases in total uterine myoelectrical activity were significant (P < 0.001) at both uterine locations as term approached, although significant (P < 0.01) variation existed between individual animals. Significant correlations between maternal progesterone (P < 0.05) and maternal and fetal estrogens (P < 0.01) and uterine myoelectrical activity were observed. The decline in maternal progesterone to levels of 2.03 ± 0.4 ng/mL and concomitant increases in both maternal and fetal total estrogens (199.3 ± 4.7 and 262.5 ± 11.0 pg/mL, respectively) resulted in a relatively high maternal estrogen/progesterone ratio just prior to parturition and corresponded to an approximate fivefold increase in total uterine electrical activity. Fetal cortisol concentrations were not significantly correlated with uterine myoelectrical activity; however, a positive correlation (P < 0.05) between fetal cortisol and maternal estrogen/progesterone ratios was obtained. The results of this study demonstrate a direct relationship between changes in the maternal estrogen/progesterone ratios and frequency and patterns of uterine electrical signals just prior to parturition, which may be ultimately triggered by the surge in fetal corticosteroid production.
