Varicocele represents abnormal dilation of the pampiniform venous plexus within the scrotum and is one of the most common reversible causes of male infertility. It is more frequently observed on the left side due to anatomical drainage patterns.
Pathophysiologically, varicocele elevates scrotal temperature, increases oxidative stress, and disrupts testicular microcirculation. These mechanisms impair spermatogenesis and may reduce testosterone production.
Clinical presentation ranges from asymptomatic findings during infertility evaluation to scrotal discomfort or testicular atrophy. Diagnosis is confirmed through physical examination and scrotal ultrasonography with Doppler assessment.
Surgical repair via microsurgical varicocelectomy can improve semen parameters and, in selected cases, enhance natural pregnancy rates. However, not all varicoceles require erotic intervention. Decision-making should consider semen quality, symptoms, and reproductive plans.
