The importance of the early detection of varicocele in adolescent males.

Varicocele is a common finding in adult and adolescent males and may lead to potential infertility. Many methods are available to the practitioner for evaluation of the problem. The least invasive is color duplex imaging of the spermatic vein, to visualize the presence of reflux (backflow) in the vein, as well as to define flow characteristics. It is recommended that adolescent males be screened using this modality beginning at age 10-15 years if they appear to have physical findings indicating a varicocele or if there is a family history of male fertility problems or varicocele. If a varicocele is found, then referral can be made for intervention if needed.
