Can a man hide his vasectomy from a doctor?

Answer 1

If a man so desired, it would be quite easy to hide the fact that he had undergone a vasectomy from a doctor. The only way a doctor could determine if a man had undergone a vasectomy without the man volunteering the information would be either physically examining the Vas Defrens or by lab testing of the man's semen. A doctor would likely never have cause to do either unless they were the one who performed the vasectomy. So most doctors would have absolutely no reason to emply the diagnostic methods needed to determine if a man has undergone a vasectomy. Similarly, the man could always refuse to allow such a thing to be performed.
