Has anyone's partner had a varicocele?

My husband discovered this in his left testicle a little over a year ago when we was doing vigorous exercise and said it caused discomfort. Naturally we went to check if everything was alright. From what I can remember they said that if it doesn't cause discomfort then he would be fine living with it. Also from what I can remember, thy said from the ultrasound that the flow pattern into both testicles was the same. We are currently 19w3d pregnant and had no issues getting pregnant. What I'm worried about is down the road when we want to have a second and maybe someday third child.. Has anyone's husband or boyfriend experience this and decided to not surgically fix it and has been able to get pregnant succefully multiple times? I don't want to have him undergo surgery if it won't cause any future issues.
