@PorcelinaV Or you could just say, "biological females". I mean, trans people don't deny that "sex is real" right? So what is wrong with saying, "biological females" or just "females"?
Or we could credit that trans men are probably smart enough to understand that women's reproductive healthcare does apply to them also.
The problem is that an awful lot of people talk about "changing sex", especially in North America. And an amazingly large number of people, especially young people - and almost all trans men are young - actually believe that if you have the surgeries and take the hormones you do physically change sex.
I have a smidgeon of sympathy for healthcare workers in this case. Some of them surely know it's BS, but feel they have to use this language in order to persuade the ignorant, the misguided and the delusional to take up appropriate health care.
Until everyone in society accepts once more that sex is binary and immutable, and declares that unequivocally, we'll continue to get this kind of language.
