Abstract

Thirteen subjects were studied to compare changes in seminal immunoreactive prolactin produced by storage and freezing of semen and seminal plasma separated within 2 hours of ejaculation. Seminal prolactin was significantly higher in semen than in seminal plasma (paired t test, t = 3.29, p <0.005). The difference in prolactin between the two values correlated with sperm count (linear regression analysis, r = 0.65, p < 0.02). This study suggested that variations in reported correlations between sperm count and seminal prolactin might be explained in part by the time interval of semen collection, centrifugation, and/or freezing.
