title: Patterns of Doppler recordings and its relationship to varicocele in infertile men.
abstract: Incompetence of the testicular vein appears to be the basic pathology of testicular dysfunction in varicocele. Doppler recording is a very sensitive method for detecting this reflux even when varicocele is not evident clinically. One hundred and seventy-eight men with infertility were studied. The presence of reflux in the pampiniform plexus as demonstrated by Doppler recording was compared with clinical varicocele. Reflux patterns were recorded on graph paper and various grades of reflux were observed. The three grades of reflux identified varied between a momentary reflux during vigorous Valsalva manoeuvre to significant reflux on minimal increase in intra-abdominal pressure brought about by normal respiration and deep breathing. Ninety-four per cent of the patients with clinical signs of varicocele had refluxes of grade 2 and 3 on Doppler study. Forty per cent of the patients without clinical evidence of varicocele were found to have reflux of grade 1 and 2 in the testicular veins.
