Summary

Varicocelectomy in adolescent boys with varicoceles improves Leydig cell function and testosterone production. This surgical correction can address early endocrine dysfunction, leading to better hormonal health.

Area of Science:

  • Pediatric Endocrinology
  • Urology
  • Reproductive Medicine

Background:

  • Varicoceles affect 5-19.5% of adolescent boys.
  • Visible left-sided varicoceles were studied in five adolescent males (17-20 years old).
  • Participants had achieved stage V pubertal development with normal testicular volumes.

Purpose of the Study:

  • To evaluate the endocrine function in adolescent boys with varicoceles.
  • To assess the impact of varicocelectomy on gonadotropin and testosterone levels.
  • To determine if varicocelectomy can correct early Leydig cell dysfunction.

Main Methods:

  • Measured serum gonadotropin (luteinizing hormone [LH] and follicle-stimulating hormone [FSH]) response to gonadotropin-releasing hormone (GnRH).
  • Measured serum testosterone response to human chorionic gonadotropin (hCG).

  • Evaluated hormonal levels before and 3 months after varicocelectomy; testicular biopsies were performed.

    • Main Results:

    • Basal gonadotropin levels were in the pubertal range, with no significant pre- vs. post-surgery difference.
    • GnRH-stimulated gonadotropin responses decreased significantly after varicocelectomy.
    • hCG-stimulated testosterone levels significantly increased after varicocelectomy (780 +/- 210 ng/dL to 1850 +/- 170 ng/dL).
    • Testicular biopsies showed normal histology and spermatogenesis.

    Conclusions:

    • Endocrine evaluation can detect early Leydig cell dysfunction in adolescent boys with varicoceles.
    • Varicocelectomy can correct this dysfunction, improving testosterone production.
    • Surgical intervention may be beneficial for hormonal health in affected adolescents.
