Hi,
I would leave things as they are. I had a vasectomy in 2000 and ended up with a hematoma of the left hemi scrotum. I received emergency surgery to ge the hematoma removed.
As a result of this, my left testicle seemd to be anchored to the upper end of the scrotum. There also seemed to be a small opening about the pin of a needle size that did not close.
When I went to see a urologist about it, I was told that I would be better off to leave it since the possibility of having to remove the left testicle was very likely.
About 2 weeks after that the once little hole in my scrotum had now transformed the left side of my scrotum to about the size of a large grapefruit,
I than underwent emergency surgery to have a left orchiectomy. It turned out to be a staph infection, and the scrotum was left open to heal from the inside out.
If you can live with it than leave it, if not you must be prepared to loose the testicle.
Good Luck,
Ron
