Sexual function following high retroperitoneal lymphadenectomy.

K R Kedia, C Markland, E E Fraley

    The Journal of Urology
    |August 1, 1975
    PubMed
    Summary

    High retroperitoneal lymphadenectomy causes infertility in most men due to nerve damage affecting sperm production. This suggests potential for new reversible male contraceptives targeting these nerves.

    Area of Science:

    • Urology
    • Reproductive Medicine
    • Surgical Oncology

    Background:

    • High retroperitoneal lymphadenectomy (HRL) is a surgical procedure used in cancer treatment.
    • Post-surgical infertility is a significant concern for patients undergoing HRL.
    • The precise mechanisms causing infertility after HRL require further elucidation.

    Purpose of the Study:

    • To investigate the underlying causes of infertility in patients following high retroperitoneal lymphadenectomy.
    • To determine the impact of HRL on specific reproductive functions and structures.
    • To explore potential therapeutic targets for mitigating post-surgical infertility.

    Main Methods:

    • Study included 36 patients who underwent high retroperitoneal lymphadenectomy.
    • Evaluation focused on the mechanisms of infertility, including seminal vesicle and ductus deferential function.
    • Assessment included analysis of sperm production, potency, orgasm, and ejaculatory function.

    Main Results:

    • Infertility was observed in 35 out of 36 patients.
    • The primary cause identified was sympathetic denervation of the seminal vesicles and ductus deferens.
    • This denervation led to aspermia (absence of sperm in ejaculate) in affected patients.
    • Potency and orgasm remained unaffected, with no instances of retrograde ejaculation.

    Conclusions:

    • Sympathetic denervation of reproductive structures is the main mechanism of infertility post-HRL.
    • The findings support the investigation of sympatholytic drugs.
    • These drugs could potentially be developed as reversible male contraceptives.
