Adolescent varicocele.

Currently, we recommend varicocele repair in adolescents when (1) the results of semen analysis are abnormal, (2) the volume of the left testis is at least 3 mL less than that of the right, (3) the response of either luteinizing hormone or FSH to Gn-RH stimulation is supranormal, (4) bilaterally palpable varicoceles are detected, or (5) a large symptomatic varicocele is present. When surgery is necessary, the Palomo approach significantly decreases the risk of operative failure and has facilitated "catch-up" growth of the left testis that is comparable to that after artery-sparing procedures. It is important to note that there is potential for impaired fertility whenever a palpable varicocele is present. Unfortunately, no test or group of tests can predict with absolute certainty whether an adolescent with a varicocele will be fertile or infertile. Therefore, it is important to observe untreated patients until they complete their families. Patients who are unwilling or unable to adhere to the follow-up protocol may be candidates for surgical intervention.
