<DIV>Max Wolf Valerio crafts a raw, gripping, and poetic account of life before, during, and after injecting testosterone. Valerio's detailed observations about a lesbian transitioning from female to a heterosexual male highlights the physical and emotional differences between women and men, and alternately challenges and confirms readers' assumptions about gender. <BR><I>The Testosterone Files</I> addresses the most fundamental issues of transitioning, from buying men's underwear to choosing a male name, as well as the profound subjects of male privilege, physical power, and existing as a male who was once distrustful and critical of men's intentions. Valerio's honest and forthcoming opinions on gender, identity, and self-perception comprise the core of this intensely personal and absorbing narrative which grapples with the tough and complex issues that emerge in a world whose assumptions about gender binaries are being increasingly challenged as more people openly self-define across the gender spectrum.</DIV>
