Maternal plasma and amniotic fluid (AF) were obtained for measurement of prolactin concentrations from: 1) 20 patients with preterm labor and intact membranes who delivered within one week of amniocentesis; 2) 20 patients with preterm labor who responded to tocolysis and delivered at term; 3) 20 women at term who were not in labor and 4) from 20 women in active labor at term. No significant differences were found between: 1) maternal plasma prolactin concentrations in women with preterm labor who delivered prematurely and those who delivered at term (155 ng/ml vs 176.5 ng/ml); 2) patients at term who were not in labor (188 ng/ml) and those who were in labor (155 ng/ml); 3) AF prolactin concentrations in the two preterm labor groups (1987.5 vs 1282.5 ng/ml) and 4) AF prolactin concentration in the two term groups (562 ng/ml vs 701 ng/ml). Prolactin concentrations were generally significantly higher preterm than at term. We concluded that no significant changes in maternal plasma and amniotic fluid prolactin levels were found in preterm and term parturition.
