Clinical and cytogenetic studies in undescended testes

Area of Science:

• Pediatric Urology
• Andrology
• Developmental Biology

Background:

• Undescended testes (cryptorchidism) and anorchia are common congenital conditions in boys.
• These conditions can impact testicular development, fertility, and endocrine function.
• Associated abnormalities may affect surgical outcomes and long-term health.

Purpose of the Study:

• To characterize the testicular volume, associated anomalies, and clinical presentation in boys with undescended testes or anorchia.
• To evaluate the impact of retention severity on testicular growth and associated conditions.
• To assess the efficacy of gonadotropin treatment and surgical interventions.

Main Methods:

• Retrospective analysis of 168 boys aged 2.5-16.8 years with undescended testes or anorchia.
• Assessment of testicular volume, presence of associated anomalies (epididymis, ductus deferens, spermatic vessels), and inguinal hernia.
• Evaluation of bone age, cytogenetic analysis, and outcomes of gonadotropin therapy and surgery.

Main Results:

• Undescended testes were significantly smaller than normal, with delayed pubertal growth. Severe retention (intra-abdominal) was noted in 25% of cases.
• Associated anomalies of the reproductive tract were present in a significant percentage of cases, particularly in anorchia.
• Inguinal hernia was a frequent comorbidity (62.8%), especially in severe cryptorchidism. One case of Klinefelter's syndrome was identified.
• Gonadotropin treatment showed success in 24% of patients, and surgical outcomes were satisfactory in 86.1% of operated testes.

Conclusions:

• Undescended testes and anorchia are associated with testicular hypoplasia and a high incidence of congenital abnormalities.
• The severity of testicular retention correlates with associated anomalies and inguinal hernia.
• While gonadotropin therapy has limited success, surgical management offers satisfactory results for undescended testes.
