Image of Aiden in transition As I hope readers of this essay can see, these videos have documented the ways in which T therapy has radically changed the very bodies of some FTM young men. This is a physical change, one which I have read it here as a form of social constructivism in which performance of gender is facilitated through very physical means including both T therapy and surgery to allow the FTM subjects of this essay (and many more I've documented) to create a richer performance of gender than changes in behavior alone (important as they are) might manage.

Most of the men in these studies describe their passing/performance as very successful. This is usually expressed by the term "100%" which means no failures in which the gender performance was challenged even in extreme situations as when Charles urinates publically in a bar with no one even noticing, a claim he makes with evident pride in several videos.

This use of physical tools—though I still maintain that they are a form of social constructivism—may require us to modify what we mean by a construct, though in no way do I wish this essay to be read as a nod towards any kind of essentialism. As a queer man, I resist the idea of biological determinism, though the changes detailed in these videos challenge me (and I hope others) to think through the boundaries and limits of constructivism.

As Lynda Birke noted in her Feminism and the Biological Body, "[. . .] opposing determinism is one thing; throwing out discussion of biology altogether is quite another. In the zeal to reject biologism, the embodied subject and the biological body seemed to be forgotten [by some feminists]" (21).

I see surgery and T therapy as one means (but only one means) to gender construction since it is clear from the vlogs produced by transmen that getting access to hormones, to the operating room, and to required therapy is not something that comes easily to transmen. It is—depending on an individual's situation—expensive and the battle to get it time consuming. Nonetheless, these physical changes, though solidly in the realm of gender as performance, still transform the body in ways that are at least as significant as is dress or changing the way one moves.

Further research here is necessary—the tension between the need to affirm constructivism (ultimately the biological cannot trump the social, especially without universal access to transformative treatments such as T) and the need to affirm the real changes caused by hormone therapy is a difficult queer position to maintain but is rich territory to explore.
