I had my vascectomy 30 years ago. It was done by my doctor in his rooms with local anaesthethic. No pain or problems. Went to the shops afterwards, had sex with my wife when we got home (just to make sure it still worked) and then did some work in the garden seeing I was having a day of work.
I had very little bruising and just a little itching from the two little scars at each side of my scrotum healing in the hot summer weather.
I notice no difference in sex and the volume of semen, if you can call it that, did not seem to change.
I have no regrets and it is a marvelous method of birth control
