Abstract

Seven young men provided a semen sample every 8 h for 2 days. Citric acid, zinc, acid phosphatase , spermine, fructose and protein were measured in the samples. Despite a dramatic reduction in semen volume, the concentration of the majority of the parameters remained constant during the period of study. The protein profile of the ejaculates, as assessed by 2-dimensional electrophoresis, also did not change. Levels of citric acid, zinc and acid phosphatase were closely correlated, while spermine, which is also believed to be of prostatic origin, showed no correlation with these other parameters. The spermine concentration of the ejaculates increased significantly during the period of high ejaculation frequency and returned to normal levels after a 3 day abstinence period. In view of the fact that spermine accumulation in tissues appears to be associated with growth and protein synthesis this increase in seminal spermine may reflect a stimulation of prostatic cell activity.
