Varicocele is more common in left side – Mechanism
- Varicocele is more commonly seen in the left side because of 3 reasons
- The left testicular vein opens at a right angle to the left renal vein
- The loaded sigmoid colon exerts pressure on the left testicular vein
- The opening of the left testicular vein is close to the opening of the adrenal veins – hence it is exposed to action of adrenergic hormones
