What is varicocele

Varicocele is characterized by the dilation of a vein (varicose) in the spermatic cord, a fibrous cord located in the scrotum above each testicle.

The varicocele occurs mainly on the left side. Venous return of the left testicle is drained to the renal vein, while the venous return of the right testicle is drained to the vena cava. The pressure of the vena cava is lower than in the renal vein.

It is quite common and benign. However, a varicocele can affect men of any age (15%). Its incidence is even higher among men with fertility problems, it could have an impact on fertility.
