Varicocele, characterized by dilation of the pampiniform venous plexus, is one of the most common correctable causes of male infertility. The pathophysiological mechanisms involve impaired venous drainage, elevated scrotal temperature, and increased oxidative stress within the testicular microenvironment.
Andrology evaluates the severity of varicocele through physical examination and imaging techniques when indicated. Not all cases require intervention; clinical decision-making depends on symptomatology, fertility goals, and laboratory findings.
When appropriately managed, correction of significant varicocele may improve spermatogenic efficiency and hormonal erotic stability. The condition illustrates the importance of vascular integrity in reproductive physiology.
