| dc.subject | Objective: Varicocele can be defined as an abnormal tortuosity and dilatation of the veins of the pampiniform plexus. Contradictory results have been obtained from experimental animal models and a few clinical human studies on testicular arterial blood flow in varicocele. The purpose of this study was to determine the changes in testicular arterial blood flow parameters in patients with varicocele. Material and Methods: A total of 62 patients with a clinical diagnosis of left varicocele and a scrotal vein with a diameter of greater than or equal to3 mm on color Doppler ultrasonography were included in the study. A total of 44 fertile normal male volunteers served as controls. Results: Median testicular arterial blood flow and median flow rate in milliliters per minute per 100 g of testicular tissue were found to be significantly decreased in the patient group compared to the control group: blood flow, 1.42 and 2.00 ml/min; flow rate, 9.63 and 12.35 ml/min/100 g, respectively (p < 0.05). Positive correlations were found between sperm concentration and left testicular artery blood flow (p < 0.05) and between left testicular volume and testicular artery blood flow (p < 0.05). Conclusions: Testicular arterial blood flow was found to be significantly decreased in men with varicocele. This may be a reflection of the impaired microcirculation. Following decreased testicular arterial blood flow, impaired spermatogenesis may result from defective energy metabolism in the microcirculatory bed. | |
