title: Correlation of ultrasound-measured venous size and reversal of flow with Valsalva with improvement in semen-analysis parameters after varicocelectomy.
abstract: We studied 68 men with varicoceles to determine preoperative parameters that are associated with improvements in semen analysis after varicocelectomy. Ultrasound-measured venous diameter and reversal of flow were found to correlate with successful outcome.
