Anti-zona pellucida activity in human sera.

A G Sacco, K S Moghissi

    Fertility and Sterility
    |May 1, 1979
    PubMed
    Summary

    Autoantibodies to the zona pellucida were detected in many human sera, including fertile and infertile individuals. This suggests that positive results may not always indicate specific autoimmunity against the zona pellucida component.

    Area of Science:

    • Reproductive immunology
    • Immunology
    • Human reproduction

    Background:

    • Autoimmunity to the zona pellucida is a potential cause of infertility.
    • Understanding the prevalence of zona pellucida autoantibodies is crucial for diagnosing infertility.

    Purpose of the Study:

    • To investigate the incidence of autoantibodies to the zona pellucida in human sera.
    • To determine if positive autoantibody detection correlates with infertility.

    Main Methods:

    • Human sera from fertile and infertile males and females were analyzed.
    • Fluorescent techniques were employed to detect autoantibodies against porcine and human zonae.

    Main Results:

    • A high prevalence of positive sera for zona pellucida autoantibodies was observed across all tested groups.
    • Positive results were found in both fertile and infertile individuals, irrespective of sex.

    Conclusions:

    • The presence of autoantibodies to the zona pellucida is common in the general population.
    • Positive autoantibody detection in female sera may not exclusively signify specific autoimmunity to a zona pellucida component, warranting further investigation into other causes of infertility.
