Unfortunately, you have not identified where these "bumps" actually are
. If they are not so much "bumps", as soft "ripples" showing in your scrotum (commonly described as a "bag of worms") when you are standing
(or sitting) but not lying down, and if you can slide your scrotum skin over
the bumps, then you probably are describing a varicocoele. If on the other hand, the "bumps" are fixed in the skin and relatively small, they are definitely not
the varicocoele - and more likely little cysts around the hair follicles.
No doubt as you are coming here and asking this question, you have already looked around a fair bit on the "net". We might wonder why you are asking it here, but I am of course, more than happy to answer - sexual health (men and women) is pretty much my field. If you note this article
for example, you will observe that the condition is common, whereas surgery for it is not common, because you only
need surgery if either you are complaining of pain, or are having an infertility problem and it is suspected the varicocoele is contributing to this.
Note that I say contributing
, because for one thing, you have two testicles and if only one is affected by a varicocoele, then it will have no effect on fertility unless the other testicle is already not working, and even then, it is unlikely to be responsible for major infertility. More importantly, the operation itself
carries a risk of damage to the testicle, so as with all surgery, there has to be a good enough reason to do it, to accept that risk.
