Perhaps. I don't know the specifics. I trust that my doctor isn't lying - she's been nothing but green flags so far - but I doubt she's as familiar with diy as the community is.
Still, I wouldn't recommend diy for anyone who has other options. Having a doctor to help you transition is really important, assuming you can find a good one.
Wow! I'm so sorry for you. Informed consent is the backbone of medical care, I couldn't imagine going to a doctor who didn't practice that.
It can be hit or miss in the US, but fortunately I live in a pretty LGBTQ friendly area. I might have to flee the country due to what's happening at the federal level, but I'm actually very happy with the resources in my local community.
