I'll get back to you on that, but just to be clear transphobia on a medical level is more about gaslighting trans people and / or denying them the treatment they need.
The doctor in question could also campaign against allowing trans rights, spread misinformation or personally deny them a referral to get the treatment they need.
Wait times for trans-specific procedures can be astronomical compared to other procedures in the same country. Think years in wait time.
I don't think most trans people complain about doctors mentioning what genitals or conditions they may have in 1-1 conversations.
All of that said, I am not trans myself, so I'm not the right person to ask. It's best to ask trans people themselves about their experiences in the healthcare industry, but they have unique challenges.
