Thanks for the replies, everyone.
I've been on HRT before, and I saw the same endo back in the day. I believe he's the only trans-specific endo in BC so he's usually booking a month or two in advance. He requires a psych referral as well as a letter from your family doctor. When he gets those, he sends over a lab requisition. He does this so he can have time to go over everything in your appointment and send you out the door with a prescription in hand. All of my blood work was handed in a month ago and he has all of my family history and health records on file. This appointment is really more to re-evaluate my transition goals and find an HRT regimen that'll work for me, as I'm not socially transitioning this time around.
Sadly, I know all about the loss of sexual desire from the four months of prior HRT experience. I have realistic expectations of how my sex life could change and my questions are tailored around that.
I've heard that progesterone can aid in breast development but haven't really researched it. Is that an old wive's tale, or is it something I should bring up with him?
