What problems are caused by varicocele?

The main problems caused by a varicocele are that it may cause pain and it may affect a man’s fertility, or his ability to have children. These are the most common reasons a man chooses to have the varicocele treated. Not all pain in the genital area is caused by a varicocele. If you are having pain, please discuss your symptoms with your healthcare provider.
