Varicocele is the dilation of which vessels?

• A. Inflammation of the epididymis.
• B. Blockage of the ureter.
• C. Dilation of the scrotal veins (pampiniform plexus).
• D. Fluid collection around the testicle.

Answer: (C)

Varicocele is the dilation of the venous network that drains the testicle, specifically the pampiniform venous plexus within the spermatic cord. When the valves in these veins fail or venous pressure rises, the veins enlarge, producing a soft, “bag of worms” feel in the scrotum that often worsens with standing or Valsalva. This is a venous issue, not a fluid collection or a tissue infection, which is why other options don’t fit. Inflammation of the epididymis would be epididymitis, a blockage of the ureter would cause urinary obstruction with potential hydronephrosis, and a fluid collection around the testicle is a hydrocele. Varicoceles can affect fertility due to increased scrotal temperature and impaired testicular function.
