@gm0nkx I had no-scalpel no-stitch, the thing is, I cannot compare it to another vasectomy
Also memory on this is starting to get a bit blurry.
Anyway, the way I remember it they put a bit of glue on the wound to bring the skin together (it's really a small wound overall) and that piece of glue came of within 2 hours post surgery on my way home, so I think the surface wound took a little longer to heal than under normal circumstances but everything healed beautifully and I was back to almost normal within 2 weeks.
The thing is, the surface wound isn't the only wound and its a bit misleading (marketing?) in the sense that what makes the vasectomy painful is not just the skin incision but also the cutting of the ducts, because the ducts aren't just passive tissue but they are surrounded by muscle.
So the painful thing about the vasectomy is the swelling due to bleeding around the ducts and (assumption on my part) that the muscle and its nerves are cut. The latter is unavoidable. The former gets worse if you move too much too early.
So I was also given the advice to cool religiously the first few days, so "that the swelling doesn't get as bad in the first place".
If you start with sport too early, you risk swelling.
