Significant reduction in left testicular volume shown by ultrasonography in infertile patients with left-side grade 2-3 varicocele as compared to less than grade 2: An evidence for indication of varicocelectomy.

Purpose: Testicular volume (TV) is known to be one of the main parameters for testicular function (TF). This study was conducted to re-evaluate the indications of a varicocelectomy based on a survey of preoperative TV results in left-side varicocele patients considered to reflect the detrimental effects of a varicocele on TF.

Methods: TV results of infertile patients determined using ultrasonography by a single expert physician were retrospectively evaluated.
