Varicocele infertility chance?

Ok I'm 16 and I think i might have varicocele in fact I'm pretty sure, and yes I know I'm not a doctor and i should have it checked, but thats not the point, I want to know if I did have it what are the chances of becoming infertile, also does it get worse over time, I've have it for a number of years, but when I go to my doctor to get a physical he doesn't say anything and I think its pretty obvious.

A varicocele is enlarged veins in the scrotum. Yes, a varicocele may get larger as most varicoceles develop over time. Also, most develop on the left side.

A varicocele can be a very common cause for low sperm production and poor sperm quality. It is also a cause for infertility. Most varicoceles are not treated unless they are causing pain or infertility. However, it is a good idea to see a urologist, the proper doctor to handle this problem, so that he can at least diagnose you and follow your condition.

Your family doctor probably doesn't mention the varicocele to you since you do not complain of any pain. Without pain, no action would be taken. And, at 16, the doctor figures you aren't seeking treatment for an infertility issue. You can bet that, if you do have a varicocele, he has documented it in your medical records though.
