BTW my dh's doc told him the risks of complications go down if you make sure a qualified urologist does it, ask him/her how many people s/he has done it on, his success rate and how many of his/her patients had complications.
And this is the biggest one, if the doc tells your dh to sit on the couch for 3 days after surgery then that is what he is supposed to do, use the ice bags, really don't lift anything etc. Many times complications arise because guys take the few days off work as a vacation and go golfing etc. My dad's friend did this the day after his vas and his testicals got all infected and swelled up like a balloon. There are no bones in the area and the area is rich in blood vessels so there isn't much that can be done to control swelling if you don't take it easy and rest! Many complications can be avoided this way. Not all of them of course but it really does make a difference in some people.
And if your dh goes through with it, about a week later he might look all bruised up but if there isn't any swelling he is ok. I had forgotten about this but a month after dh's he had a bit of pain and some redness/itching turns out he got a mild skin infection in the area which they treated with antibiotics. Could have been because he didn't change his dressing as often as he should have the first week and then we resumed 'relations'
way before we were supposed to, that could have contributed also.
And again if he goes through with it after the initial healing is done and the stitches disolve or are taken out there might be a tiny hole is what it looks like but it usually goes away about 2 weeks after the stitches come out. If it gets bigger or doesn't start to heal up have the doc re-look at it but from talking to others that had it done my dh realized it's pretty normal but at first he was concerned.
