[Testosterone serum concentrations after subcapsular orchiectomy (author's transl)]

T Senge, T Hülshoff, U Tunn

    Der Urologe. Ausg. A
    |November 1, 1978

    Summary

    Subcapsular orchiectomy in advanced prostate cancer patients led to sustained low testosterone levels. Human chorionic gonadotropin (hCG) stimulation did not restore testosterone production, indicating permanent testicular suppression.

    Area of Science:

    • Urology
    • Endocrinology
    • Oncology

    Context:

    • Advanced prostatic carcinoma (stage C or D) often requires hormonal therapy.
    • Orchiectomy is a surgical method to reduce androgen levels.
    • Subcapsular orchiectomy aims to preserve the scrotal sac appearance.

    Purpose:

    • To evaluate the long-term effects of subcapsular orchiectomy on serum testosterone levels.
    • To assess the residual testicular function after subcapsular orchiectomy.
    • To determine if human chorionic gonadotropin (hCG) can stimulate testosterone production post-orchiectomy.

    Summary:

    • Twelve patients with stage C or D prostate cancer underwent subcapsular orchiectomy.
    • Serum testosterone levels were monitored for up to eight months post-surgery.

    Related Experiment Videos

  • Testosterone levels initially decreased and then stabilized between 0.42-0.67 ng/ml.
  • Subsequent hCG stimulation failed to increase testosterone concentrations.

    • Impact:

    • Subcapsular orchiectomy results in profound and sustained suppression of testosterone production.
    • This procedure effectively achieves medical castration, similar to other orchiectomy methods.
    • Findings suggest permanent testicular suppression, impacting future hormonal management considerations.
