| Abstract: | The composition of seminal plasma in the sperm-rich split ejaculate fraction was studied in a group of men with a low zinc content in their sperm chromatin, to evaluate the availability of zinc at ejaculation. Men with low-chromatin zinc had, in the sperm-rich split-ejaculate fraction, high amounts of seminal-vesicular fluid, a low zinc:fructose molar ratio, and a high percentage of zinc bound to high molecular weight ligands of seminal vesicular origin (HMW-Zn). This indicates premature admixture of vesicular fluid at ejaculation. It is suggested that the zinc:fructose molar ratio and HMW-Zn in the sperm-rich fractions could be used as a measure of the availability of zinc in seminal plasma. |
