Histoincompatibility in couples with unexplained infertility.

E Persitz, J R Oksenberg, E J Margalioth

    Fertility and Sterility
    |May 1, 1985
    PubMed
    Summary

    Human leukocyte antigen (HLA) frequencies did not differ between couples with unexplained infertility and fertile controls. Shared HLA antigens and mixed lymphocyte culture reactivity were also similar, suggesting HLA compatibility is not a cause of infertility.

    Area of Science:

    • Immunogenetics
    • Reproductive Medicine
    • Human Leukocyte Antigens

    Background:

    • Human leukocyte antigens (HLA) play a crucial role in immune responses.
    • Infertility can have various causes, and immune factors are sometimes implicated.
    • Previous research has explored the link between HLA compatibility and reproductive success.

    Purpose of the Study:

    • To investigate the association between human leukocyte antigen (HLA) antigen frequencies and unexplained infertility.
    • To compare HLA antigen sharing and mixed lymphocyte culture (MLC) reactivity in infertile couples versus fertile controls.

    Main Methods:

    • Determined Class I (HLA-A, -B) and Class II (HLA-DR) antigens in 18 infertile couples.
    • Compared HLA antigen frequencies with 30 fertile couples and a control cell panel.

  • Assessed one-way mixed lymphocyte culture (MLC) reactivity in infertile pairs.

    • Main Results:

    • No significant differences in HLA-A, -B, or -DR antigen frequencies were found between infertile and control groups.
    • The frequency of shared HLA antigens within couples was similar across all study groups.
    • MLC tests demonstrated normal immune reactivity in infertile couples.

    Conclusions:

    • HLA antigen profiles do not appear to be a significant factor in unexplained infertility in the studied population.
    • Immune compatibility, as assessed by HLA sharing and MLC, is unlikely to be the primary cause of infertility in these couples.
