Yes. Everyone should have autonomy over their own bodies, especially when it's a matter of something as major as pregnancy. Pregnancy is a medical condition, and the only person that should (legally) have any input in medical decision making for pregnancy is the person that's pregnant.

The mother clearly has a bigger stake in pregnancy than a father and I can't believe this needs to be explained. Yes, women get to choose if they want to be mothers for a variety of complicated and nuanced reasons. For men they can simply choose to not raw dog a woman. Obviously it's different if they were raped or their semen was stolen but those are much more rare cases.

The father made that choice when he decided it was a good idea to fuck without protection. You don't get to undo mistakes you made by telling someone else to undergo a medical procedure they don't want. It doesn't matter if you realized your mistake the next day and started telling them to use plan B. You can not want a baby all you want, but the only thing that matters is, did you willingly play your part in making it?
