Varicocele is the dilation of veins or varicose veins around the testicle. They are located around the testicle, inside the scrotum (skin that involves the testicles), and are much more frequent on the left than on the right.\u00a0<\/strong><\/p>\n The veins responsible for the varicocele are called spermatic or testicular veins, and they pass inside the spermatic cord, in the inguinal route.\u00a0<\/strong><\/p>\n Varicocele is more frequent on the left because the left testicular or spermatic vein drains into the left renal vein at a right angle, while the right testicular or spermatic vein drains into the inferior vena cava at a more favorable angle.<\/span><\/p>\n<\/div><\/div><\/div>
