Abstract
Varicocele is clinically defined as an abnormal dilatation of the veins of the pampiniform plexus with continuous or intermittent reflux of the venous blood. It is actually considered the most common correctable cause of male infertility, even though the mechanisms responsible for infertility are still unclear. The prevalence of this disorder in the general population is approximately 15–20 % [1], and it is involved in up to 40 % of cases of men infertility [2–4].
