Undescended testes: treatment with gonadotropin

Area of Science:

• Pediatric Surgery
• Endocrinology
• Urology

Background:

• Testicular maldescent, or undescended testes, is a common congenital condition in infants.
• Successful treatment requires evaluation of both testicular descent and subsequent fertility.
• Indications for surgical intervention include ectopia, hernias, and advanced puberty.

Purpose of the Study:

• To evaluate the therapeutic success of human chorionic gonadotropin (hCG) treatment for testicular maldescent.
• To assess the impact of treatment on fertility outcomes.
• To determine the optimal timing and indications for intervention.

Main Methods:

• Analysis of large European and American clinical statistics on hCG treatment for testicular maldescent.
• Comparison of success rates based on inclusion criteria (prescrotal testes, retractile testes).
• Evaluation of fertility rates in relation to treatment response (hormonal vs. surgical).

Main Results:

• hCG treatment shows success rates of 50-55% in European studies and 30-40% in American studies.
• Ectopic testes were more common in cases unresponsive to hormonal treatment requiring surgery.
• Fertility rates were higher in cases achieving descent with hCG alone compared to those requiring additional surgery.

Conclusions:

• hCG treatment is indicated for testicular maldescent unless surgical intervention is clearly necessary.
• The second year of life is the optimal period for initiating hCG therapy.
• Unilateral testicular maldescent generally has a better fertility prognosis than bilateral cases.
