Why are varicose veins on the left?

Varicocele is the left side may be caused by long veins, increased blood flow resistance, sigmoid compression and other reasons.

1, the left side of the

spermatic vein length is longer than the right testicle spermatic vein, due to the increase in the length of the vein leads to increased internal pressure, so the left side of the disease is more likely than the right side.

2, blood flow resistance increased

left spermatic vein blood flow into the ipsilateral renal vein, easily leading to increased blood circulation resistance, resulting in left varicocele.

3, sigmoid compression

The lower segment of the left spermatic vein is prone to sigmoid compression, increased venous pressure, so the incidence of left is higher than the right.
