My brother had this operation many moons ago, when he was still in the army.

It was done in London, at a private clinic and, after resting for an hour he got on his motor bike and rode back to his unit - in Germany. He reckoned he was a bit sore for a while after. Eighteen months later he contracted mumps....

Good on you guys if you go for this. My ex went so deathly pale when it was suggested, once we decided not to have more children, that I ended up having the tubes cut instead.
