Hey Nic,
I had it done 3 years ago. My wife and I decided that after 3 kids ( and 2 miscarriages) our child bearing years were behind us; it seemed like the responsible thing to do. I had the exam to see if I was " a candidate". I also signed the forms.
The procedure lasts about 10 minutes; mine was TOTALLY painless, required 2 stitches ( dissolving) and had no after effects. I was back in action the next day.
It was a little embarrassing to be spread eagled on the table while the female doctors assistant " handled things" , the doctor performing the procedure was male.. It was even more embarrassing 1 month later to bring a sperm sample to the lab to assure that the procedure worked, prior to having any unprotected sex.
It was the best thing I ever did; to this day the hydraulics work as good as ever; but it is a personal decision. Some guys just do not want to do it; and that is OK.
