Gonadotropin-releasing hormone stimulation testing was performed on 10
4 adolescent males with a unilateral left varicocele to determine the
frequency of testicular dysfunction in this group of patients. An abno
rmal test result was noted in approximately 30 percent of varicocele p
atients. We believe that an abnormal test result indicates a higher ri
sk for future fertility problems, and early treatment may reduce this
risk.
