Prolactin and plasma prostaglandin metabolite levels in patients undergoing nipple stimulation contraction stress tests

Twenty-five patients undergoing nipple stimulation contraction stress tests were enrolled in this study. Plasma 13,14-dihydro, 15-keto prostaglandin F2 alpha and plasma prolactin concentrations were analyzed before and during the contraction stress tests. Prolactin concentrations were significantly higher (p less than 0.01) in patients who responded with a successful stress test versus those who did not. No significant changes were observed in the mean concentration of plasma 13,14-dihydro, 15-keto prostaglandin F2 alpha levels between the two groups.
