Clinical Significance of GnRH Stimulation Test in Adolescent Varicocele / 대한비뇨기과학회지

ABSTRACT

We measured the gonadotropin responses to the intravenous injection of gonadotropin releasing hormone(GnRH) in 16 adolescent varicocele patients and the results were compared with those of normal control group. After GnRH stimulation, LH response was very exaggerated in all the adolescent varicocele patients compared to the response of normal control but FSH response was not different from that of normal control. Testicular size and size difference were not correlated with GnRH stimulation test. We suggest that GnRH stimulation test may detect testicular dysfunction before the change in testicular size and early treatment may reduce the potential risk for infertility in adolescent varicocele patients, but long term follow up will be required to confirm our data.
