Abstract

The relationship between varicocele and infertility has long been defined. About a third of the male patients undergoing evaluation for infertility present with a varicocele. Sixty male patients between 17 and 35 years of age (mean 25.6) were examined with a colour-doppler flow imaging system. The diameters of the veins in the pampiniform plexus were measured by gray-scale sonography. Our findings were classified with regard to venous diameter, the existence or non-existence of reflux, the circumstances under which these findings were recorded (e.g. during normal respiration and standing position or during Valsalva manoeuvre and supine position). Finally our results suggest that: (a) the clinical significance of the presence of dilated veins or reflux during increased intraabdominal pressure and under similar circumstances should be regarded with caution; (b) positive findings during normal inspirium are highly significant (grades III and IV).
