    Summary

    This study measured zinc levels in human seminal plasma, finding concentrations between 2.5-25.7 mg%. Zinc is crucial for sperm motility and creating a conducive environment for sperm activity.

    Area of Science:

    • Biochemistry
    • Reproductive Biology
    • Analytical Chemistry

    Background:

    • Seminal plasma is vital for sperm function.
    • Zinc is a key trace element in biological systems.
    • Understanding seminal plasma composition is important for reproductive health.

    Purpose of the Study:

    • To quantify zinc concentration in normal human seminal plasma.
    • To explore the functional roles of zinc in seminal plasma.
    • To investigate the necessity of zinc for sperm motility and activity.

    Main Methods:

    • Instrumental neutron activation analysis (INAA) was used for zinc quantification.
    • Analysis was performed on samples from normal human seminal plasma (n=9).

    Main Results:

    • Zinc concentration in normal human seminal plasma ranged from 2.5 to 25.7 mg%.
    • Two primary functions of seminal plasma zinc were identified: supporting sperm motility and facilitating sperm activity.
    • The role of zinc in providing a favorable medium for sperm activity can be substituted by other ions.

    Conclusions:

    • Zinc plays a dual essential role in human seminal plasma, directly impacting sperm motility and indirectly supporting sperm function.
    • The concentration of zinc in seminal plasma is significant, with a defined range observed in healthy individuals.
    • While essential for sperm activity, the environmental role of seminal plasma zinc is not unique and can be fulfilled by alternative ions.
