Phosphate, zinc, calcium, citric acid, and acid phosphatase in human ejaculates as related to coagulation/liquefaction.

Variations in the coagulation-liquefaction property of human seminal coagula have rarely been correlated to their ingredients. A number of seminal components were evaluated in relation to the degree of coagulation and the liquefaction time of human ejaculates. Correlation analyses suggested that the vesicular coagulatory activity can better be assessed by the phosphate level rather than the fructose and N-acetylamino sugar levels. The results showed that the fresh ejaculates with a smaller amount of coagulum possess significantly higher prostatic but lower vesicular activities in comparison with that of the better coagulating samples. The study also revealed that liquefaction time-based fractionation of the whole ejaculate seems to give an idea about the origin of some seminal components like split ejaculation technique. It was concluded that the material characteristics of human ejaculate can be approximated simply by determining its degree of coagulation or liquefaction time.
