Enzyme activities of human seminal plasma having different states of coagulation.
Aminopeptidase, a chymotrypsin-like enzyme, and alpha-d-glucosidase activites of human seminal plasma were compared amongst four groups of human ejaculates, classified according to initial state of coagulation, i.e., coagulated, fully gelled, partly gelled, and liquid. Liquefaction times of liquid and partly gelled groups were significantly lower than those of the other two groups. Aminopeptidase was significantly higher in liquid and partly gelled groups in comparison with that of coagulated and fully gelled ejaculates. Activities of the other two enzymes did not differ significantly among the four semen groups.
