[Changes in blood prolactin in relation to the menstrual cycle].
Scientists are in general agreement on the hypothesis of a prolactin surge at midcycle. In order to test this hypothesis the Authors measured radioimmunoassayable circulating prolactin in the follicular phase and at midcycle in 15 normally menstruating health women. Due to the well known individual variability, mean prolactin values showed statistically poor differences in the two phases of the cycle. Though, a very good positive correlation (r = 0.72, p less than 0.01) was shown when individual follicular values were plotted against the corresponding midcycle values. The Authors conclude that at midcycle prolactin increases significantly and discuss physiological significance of this phenomenon.
