What to do if i discovered out i have a varicocele, is this harmful?

Don't worry: Varicoceles may sometimes be associated with male infertility. You have nothing to worry about if you already have children & most men with varicoceles are perfectly fertile. U can get a semen analysis, if plan to be a father & check for sperm count & % of motile forms. If U wish fatherhood & counts low, or varicocele painful or uncomfortable might consider spermatic vein ligation/varicocelectomy
