Summary
True undescended testes, often unilateral, require orchiopexy before age 3 for optimal sperm function. Early intervention is crucial as testes don't mature normally after age 2 and can affect the other testis.
Area of Science:
- Pediatric Surgery
- Urology
- Developmental Biology
Background:
- True undescended testes (cryptorchidism) are common in infants.
- Unilateral cases account for approximately 80% of true undescended testes.
- Human chorionic gonadotropin (hCG) is rarely effective for correction.
Purpose of the Study:
- To outline optimal management strategies for true undescended testes.
- To emphasize the critical age window for surgical intervention.
- To discuss the implications of testicular position on morphology and function.
Main Methods:
- Review of current clinical guidelines and literature on cryptorchidism management.
- Analysis of the relationship between testicular position, age at intervention, and outcomes.
- Evaluation of the impact of cryptorchidism on testicular development and fertility.
Main Results:
- Orchiopexy before age 3 is recommended for optimal tubular development and sperm function.
- Testicular maturation is impaired after age 2, potentially affecting the contralateral testis.
- Higher testicular position correlates with increased dysgenesis; hypoplastic testes warrant early removal.
Conclusions:
- Timely orchiopexy is essential for preserving testicular function in cases of true undescended testes.
- Delayed surgical correction, especially before midadolescence for high-positioned testes, may necessitate orchiectomy.
- Management should consider testicular position, morphology, and potential adverse effects on fertility.
