I heard a teacher say that some girls can self fertilize themselves.. no doctors or anything... just... yeah.. is that even possible??
Yes and no. They can get pregeant by not having sex, but the only way to do that is for an injection up down there... if you know what im getting at. watch the movie "Baby Mamma", the whole plot is based around that...its an awesome movie, and educational in the question you're asking.
No. There are some animals that can. Humans cannot self fertilize. If you're religious, even Mary needed some help from God.
