Abstract
Varicocele is a common cause of male infertility; it can be treated by percutaneous retrograde embolization of the internal spermatic vein in order to improve sperm parameters and male fertility. The aim of this study was to verify the improvement of semen parameters after varicocele retrograde sclerotherapy. We evaluated 223 patients with left (206) or bilateral (17) varicocele (mean age±SD, 27.3±4.7 yr, range 18–37) by clinical, Doppler and seminal examinations; all the patients underwent phlebography, using 5F Cobra catheter from the right femoral vein access to the internal spermatic vein and varicocele sclerosing with Hydroxy-polyaethoxydodecanol. Doppler and seminal examinations 6 months after sclerotherapy were requested for the follow-up. Sixty-seven patients with left or bilateral varicocele who did not undergo sclerotherapy were studied as controls. Six months after sclerotherapy, a complete resolution of left varicocele was present in 172 patients (77.1%), while a partial improvement was obtained in 34 patients (15.3%). In these 206 patients seminal examination showed a significant improvement of sperm concentration (mean±SEM, 52.1±4.1 vs 44.2±3.6 million/ml, p=0.002) and progressive motility (40.5±2.2 vs 33.3±2.0%, p=0.0001), but not of normal sperm morphology (38.9±2.3 vs 37.4±2.1%, ns). In the control group no significant variations of seminal parameters were observed 6 months after the basal examination. In conclusion, varicocele retrograde sclerotherapy is a well-tolerated technique with a low cost-benefit ratio, able to improve semen parameters.
