abstract = {What to do with the adolescent varicocele? With merging the information obtained from an extensive review of the literature with our own clinical research, I believe that we already have knowledge enough to say that the adolescent with a varicocele often is in the midst of a progressive disease process. Strong evidence already exists that well more than the majority of Tanner 5 boys with a varicocele and 20% asymmetry will already have abnormally low total motile sperm counts (TMCs) and likely abnormally low sperm concentration as well. There are now many studies in addition to common sense to support the value of % asymmetry as a marker of future abnormal sperm parameters. While we know that some boys at lower Tanner stages who present with asymmetry will have catch-up growth during adolescence, we also know that almost all boys with 15% asymmetry or greater in conjunction with a Doppler detected peak retrograde flow (PRF) of 38 cm/s or greater will end up with greater than 20% asymmetry on follow-up. There also are some boys of concern with less asymmetry but instead have small testes bilaterally, perhaps as a result of the left varicocele slowing the growth of the right testicle and/or an associated undetected or overlooked palpable right varicocele that is also negatively affecting the right testicle. Fortunately, we now have another marker available, i.e., total testicular volume (TTV), to assist in decision making for the adolescent falling into this scenario. Once markers are in place in an early Tanner stage boy with a varicocele that indicate that abnormal semen parameters will likely be present when a Tanner 5 stage of development is reached, there is no reason to wait until the child is older so that a semen analysis can be comfortably requested for the documentation. One argument in favor of waiting is that abnormal semen parameters in a Tanner 5 male usually are reversible. However, how do we know that once abnormal parameters are reversed they then will stay normal in a testicle that already has incurred damage. In other words, I feel it is best to operate once the indicators are in place. We do not want to be suddenly surprised when that individual when older has difficulty fathering a child at a time in life when surgery might be too late to resolve what has taken years to develop. Within this manuscript I will try to document my reasons for the aforementioned rationale.},
