What can I expect from my vasectomy?

A little discomfort for a few days and most likely no problems (AS LONG AS YOU FOLLOW DOCTORS INSTRUCTIONS). Afterwhich you will have plenty of carefree never having to worry about pregnancy again. Oh, do use some form of birth control till you get the "all clear" from both after tests. I have two female cousins whos husbands did not, and sure enough, preggers again.
