Varicocele

A varicocele is an abnormal dilation of the internal spermatic veins and pampiniform plexus that drain blood from the testis.

Incidence is 15% in adolescent boys and adult men; 90% occur on the left side; 10% are bilateral.

May impede adolescent testicular growth and affect adult sperm parameters and testosterone production.

40% of men being evaluated in a male fertility clinic will have a varicocele.

Diagnosis is usually clinical; ultrasound may be helpful where there is doubt about the diagnosis.

Surgical correction may reverse testicular growth arrest in adolescents and improve semen parameters in adults.
