Abstract
PURPOSE: The aim of this study is to evaluate the potential effect of varicocele in the hormonal and clinical profile of adolescents. METHODS: Twenty adolescents at Tanner stage 4-5 with left varicocele were studied and compared with a control group of 20 healthy adolescents. All patients underwent ultrasonographic testicular volumetry as well as hormonal evaluation of inhibin B, testosterone, baseline and gonadotropin-releasing hormone stimulated, follicle-stimulating hormone as well as luteinizing hormone. Statistical analysis was performed using the student's t test with p value <0.05 taken as statistical significant. RESULTS: Patients with varicocele showed reduced levels of inhibin B compared to controls and a significant reduction in the testicular volume on the affected side. The response of luteinizing hormone to gonadotropin-releasing hormone stimulation was significantly higher in the varicocele group compared to the control group. Furthermore a significant inverse relationship of inhibin B compared to follicle-stimulating hormone was noted. CONCLUSION: Serum inhibin B levels could represent a useful marker of Sertoli cell damage caused by varicocele.
