If you value bodily autonomy (which I really hope you do – otherwise this discussion is kind of pointless) the only person who can decide what happens with their own body is the actual pregnant person – and no one else. This consequently means that we can only put this decision into their hands. It’s a function of the biological difference.
I mean, misogynist assholes like to bang on and on and on about biological differences (most often referring to things we don’t even really know are biological differences) and how those make it imperative to treat genders differently – but here we have a crystal clear example of a biological difference leading to different options for different people – and suddenly that’s no ok?
