I went the informed consent route also, and my experience mirrors Devlyn's. The medical assistant asked about any general health issues, checked height and weight, then took blood pressure. Needless to say my BP was high due to being nervous and excited. Doctor came in and reviewed blood tests, then asked about my background and why I wanted HRT. I told the doctor my story, and after a few more generic questions I signed the paperwork and my prescription was on the way to my pharmacy. I did not feel that any gatekeeping was involved. I still present as 100% male, and that did not have any affect on the discussion.
For now I am taking finasteride (for BPH) and estradiol patches. My next checkup is end of July to see how things are progressing. Estradiol alone may work for some folks. Even without spironolactone, I was happy to get the journey started.
Best of luck on you appointment!
