Either or both. Vasectomy is usually outpatient.
only if the doctor didnt do the visectomy right
The male or female could wear a condom, this reduces the chance of it happening. If you never want to ever give birth to your own children, the male could get a visectomy, or the female could get her tubes tied. (male procedure is much safer) But do not get this done without second thought.
Temporary are methods like the a condom, the pill, the patch, or the ring. Things like that at which you can stop using at any time to try to become pregnant. Permanent methods are like a visectomy or getting your tubes tied. Things that will last for the rest of your life if you decide you never want a baby.
It happened to my mom and step dad. My mom had a tubal done 11 years ago (at the time it happened) and my stepdad had a visectomy done 13 years ago(from the time it happened). A vasectomy is not considered 100% effective and the doctors told my mom after 10 years tubes can come untied. And that's how my little half sister got here. Remember, nothing is ever considered 100% effective, weird huh?
