This study aimed to search whether there is a link between reflux flow and hormonal profile. Data of 250 patients were retrospectively investigated. Pre-operative and 6th month semen analyses of these patients' results were compared with pre-operative and post-operative 6th month serum levels of testosterone. Based on the venous flow on pre-operative Doppler ultrasonography, patients were divided into two groups. Patients with a venous flow ≤4 s were assigned to Group 1 and those with a venous flow >4 s to Group 2. Venous reflux time cut-off was calculated as 4 s using ROC curve according to the increase in testosterone level. When venous reflux time was selected as approximately 4.0 s, ROC had 79.8% sensitivity and 72.8 specificity. The probability of a post-operative increase in testosterone is high in patients with a venous reflux time longer than 4 s.
