Amino sugar levels in normally coagulating and poorly coagulating human ejaculates.

Free and total amino sugar levels were determined in human prostatic fluid, vasectomized semen, presumably fertile semen, and in ejaculates having different degrees of coagulation. About 87% of the total amino sugar in seminal plasma was found in the bound form. The seminal vesicles were the richest source for seminal amino sugar, being followed by the prostate, while the epididymes contributed negligibly, if at all. Total amino sugar level of the poorly coagulating ejaculates was found to be significantly lower than those of the vasectomized, presumably fertile, and normally coagulating ejaculates. The degree of coagulation and the amino sugar level of human ejaculates were related by a correlation coefficient of .468 (n = 60; P less than .001).
