How serious is a grade 1 subclinical varicoele? I m 35 years old, and I was just diagnosed with a grade 1 varicocele . Can a grade 1 varicocele affect fertility? My wife and I are trying to conceive. - my sperm count is 10 mil, but my motility and everything else are fine. Is my varicocele and low sperm count related? Why or why not? - about 5 years ago I experienced a dull ache in my testicles . It either eventually went away, or I just got used to it. After researching online (big mistake I know), I read that swollen varicoceles can cause this. Can a grade 1 varicocele cause this? I only ask because the ache only returned after I got the news. Is it all in my head? - can varicoceles get worse? over time, can it go from a grade 1 to a grade 3? Can grade 1 develop to the worm stage? - if the ache does not go away, should I consider surgery? Would that help my fertility chances as well?
