i think the answer is obvious. you have no sperm. you are sterile. you cannot father a child anymore (unless you have a vasectomy reversal). if your girlfriend is pregnant you cannot be the father. just in case repeat your semen analysis. many women want to become pregnant so desperately they can create some of the symptoms to the point where they believe it is true. go with her to the gynecologist. see the pregnancy test or the ultrasound. if she is truly pregnant then you will need to have a long talk.
my girlfriend says she's pregnant. i had a vasectomy and a sperm analysis test & showed no live sperm is this possible?
