Answer
A varicocele is much more common on the left side due to a simple difference in your body's anatomy and how your veins are structured. The left testicular vein, which drains blood from your left testicle, has a longer and more vertical path to follow before it connects to a larger vein in your abdomen (the left renal vein). It joins this larger vein at a sharp, 90-degree angle. This plumbing arrangement can make it harder for blood to flow out efficiently, creating higher pressure in the left testicular vein. In contrast, the right testicular vein has a shorter, more direct path and joins a major vein (the vena cava) at a gentler angle, allowing for easier blood flow.
This anatomical difference is the primary reason why about 80-90% of all varicoceles occur on the left side. Understanding your body is important, and the experts at SCI hospital can provide clear explanations. For any concerns, schedule an online or offline consultation with us.
