Why Testicular varicocele would occur mostly on the left testis veins or left pampiniform plexus

Testicular varicocele predominantly occurs on the left side due to anatomical and physiological factors: Venous Drainage Anatomy: The left testicular vein drains into the left renal vein at a right angle, which creates higher venous pressure compared to the right testicular vein, which drains directly into the inferior vena cava2. Valve Dysfunction: The valves in the veins of the pampiniform plexus may be incompetent or absent, leading to blood pooling and vein dilation. This is more pronounced on the left side due to the longer course of the left testicular vein. Nutcracker Syndrome: Compression of the left renal vein between the aorta and the superior mesenteric artery can increase venous pressure, contributing to left-sided varicocele. Gravity and Blood Flow: The vertical orientation of the left testicular vein makes it more susceptible to gravitational effects, which can exacerbate venous pooling #varicocele
