Ran into this while searching for gender therapists. It's a 250 page report on transmen, testosterone, and masculinity. I have yet to read any of it, but the table of contents looks pretty awesome. They even have an embodiment/phenomenology piece, which especially excites me because I've never come across another person who wrote about this before in the transgender sense, let alone in the FtM sense. The author's sources show that they really did their work. I have to admit I'm a little jealous that somebody beat me to it...and with many of the same sources! Well, now I have something to cite.
