Surgical repair appears to have higher risks than varicocele embolization, with no clear advantage in terms of success rates, implying that embolization may be the preferred option for unilateral varicoceles in infertile men. What are the potential side effects of varicocele embolization? The technique is completely risk-free. Infection is one of the very infrequent dangers. The use of cyanoacrylate glue for varicocele embolization was found to be as safe as other embolic materials, resulting in less radiation (shorter scope duration, less kinetic energy emitted per unit mass, lower DAP) and a lower recurrence rate than other embolic materials.
