Why does that only apply to trans people and how they want to be addressed? What about cis-women that want to be addressed as women, but now the medical profession is refusing to grant them that basic request for dignity?
I also don't just mean accomodation in terms of words: if trans men have any needs different to cis women, then medical literature on pregancy must include this when in circumstances where it's appropriate.
Serious question: do you suppose that that trans men have different needs than cis women (in a medical sense) with regard to pregnancy?
That said, if they've transitioned they (I think) need to stop taking testosterone, which points out that hormone stuff could perhaps be different. There's also the social aspect of a man attending/needing typically women only support.
