Luteinizing release hormone tests in impotent diabetic males

A D Wright, D R London, G Holder

    Diabetes
    |October 1, 1976
    PubMed
    Summary

    Diabetic impotence in men may stem from nerve issues, not hormone imbalances. Pituitary-gonadal function tests showed no significant endocrine differences in impotent diabetic men compared to controls.

    Area of Science:

    • Endocrinology
    • Neurology
    • Diabetology

    Background:

    • Diabetic males frequently experience impotence.
    • The underlying cause, endocrine versus neurologic, remains debated.

    Purpose of the Study:

    • To assess pituitary-gonadal function in impotent diabetic males.
    • To differentiate between endocrine and neurologic causes of impotence in this population.

    Main Methods:

    • Luteinizing hormone-releasing hormone (LHRH) tests were administered.
    • Serum testosterone and sex-hormone-binding globulin (SHBG) capacity were measured.
    • Basal and incremental gonadotrophin concentrations were analyzed.

    Main Results:

    • Impotent diabetic males exhibited similar serum testosterone levels to controls.
    • Similar sex-hormone-binding globulin capacity was observed in both groups.
    • Basal and incremental gonadotrophin concentrations did not differ significantly.

    Conclusions:

    • Findings suggest a primary neurologic defect, not an endocrine one, underlies impotence in diabetic males.
    • Pituitary-gonadal function appears preserved in impotent diabetic men.
    • Further investigation into neurologic pathways is warranted.
