What causes a varicocele?

There are several theories as to what causes varicoceles, however, none have been conclusively proven.

Is a varicocele harmful to my son?

Probably not. However, some varicoceles can inhibit growth of the testicle, and are found in 4 out of 10 men with infertility problems, making them the most common reversible cause of male infertility. The relationship between the size of the varicocele and the potential risk for infertility is unclear.
