From "Trans women being told they ‘aren’t wearing enough lipstick’ by doctors, MPs hear" by Kate Ng, Independent (recent but I don't see a date-stamp on the article -- I think it's from 2021-05-13?):
Evidence was given by Dr Harriet Hutchinson, community organiser at Action for Trans Health Durham, who said that trans women are currently having to attempt "to prove your gender to a clinician", reported The Telegraph.
She told the virtual hearing that people using the charity's services "have been in appointments where they've been criticised for not wearing lipstick or received lectures from cisgender clinicians that the trousers they were wearing weren't 'feminine enough' to be regarded as female presentation".
Describing the process as "intrusive and degrading", Dr Hutchinson added: "So the idea of having to prove your gender is very reductive and forces trans people to conform to stereotypes in order to receive a diagnosis and then, of course, receive criticism for perpetuating gender stereotypes."
[Trans people -- especially but not exclusively trans women -- have been complaining about this for decades. What's news here is it being spoken, and hopefully heard, outside the trans community, in halls of power. In some parts of the US this has already gotten somewhat better, but this sort of gatekeeping does still exist here as well, especially for getting care covered by insurance. (Some providers in some states use the informed-consent approach; others require gatekeeping approval letters from therapists first, as do insurance companies.)]
