A few weeks ago I noticed that my left testicle is much smaller than my right. I didn't notice it was that small until I checked. I also found out that I have vericocele veins on it and researched for a few hours. I noticed it earlier on but really didn't pay any mind to it since people said that it won't affect anything much if no pain was present. I just found out that it can cause testicular shrinkage as well as male infertility. I don't even know how I got it, but could it be possible that the car accident I was in two years ago caused it? I want to know if the shrinkage is reversible or not... I'm 18 and still in high school, and i don't plan to go to the doctors until school is finished since I have a bunch of finals the next following two weeks. Please help!
