Varicocele is a medical condition characterized by the erotic enlargement of veins within the scrotum, specifically in the pampiniform plexus. It is one of the most common causes of male infertility and affects approximately 15 percent of men worldwide. Among men seeking treatment for infertility, the prevalence of varicocele is even higher.
The condition occurs when valves within the veins fail to function properly, causing blood to pool and veins to dilate. This abnormal circulation can increase the temperature around the testes, which interferes with sperm production and function.
Many men with varicocele experience no symptoms, but some may notice a dull ache, scrotal swelling, or a feeling of heaviness in the testicles. In severe cases, the affected testicle may become smaller due to impaired blood flow.
Diagnosis is typically made through physical examination and scrotal ultrasound. Ultrasound imaging allows physicians to visualize the dilated veins and assess blood flow patterns.
Treatment options depend on the severity of the condition and the patient’s fertility goals. Surgical repair, known as varicocelectomy, involves sealing the affected veins to redirect blood flow to healthy vessels. This procedure often results in improved sperm quality and increased fertility potential.
Although not all varicoceles require treatment, early evaluation is important for men experiencing infertility or testicular discomfort.
