Written for general audiences, this unprecedented book comprehensively answers many questions about being transgender with current experiential and scientific information, including the evidence for a biological transgender predisposition. With transgender people visibly achieving fame in entertainment, the literary world, and other arenas, increasing numbers of transgender people are choosing to publicly announce that they are transgender. All of this has brought transgender people and the associated issues of being transgender into mainstream discourse. The demand for fact-based, scientific information on being transgender has never been higher. Written by a transgender person who is also a physiological psychologist, this book is the first for general readers that explains what is known about transgender causation, what life as a transgendered individual is like, and the science involved in living a transgender life. This book serves to improve understanding of being transgender among general audiences-including transgender readers-by describing the science and experience of being transgender. It supplies an enlightening understanding of what if feels like to be transgender, when it starts, the many paths for living a transgender life, and methods to face challenges such as bullying and rejection. It provides a worldview that transgender people are neither broken nor diseased, but rather that they exhibit transgender behavior because of a biological predisposition for which there is solid scientific evidence. Offers information derived from the author's review of more than 3,000 source articles and books across 22 scientific disciplines across more than 11 years-a repository of information that is likely the most comprehensive on transgender science Represents the first book written for general audiences from the perspective of a scientist, not a clinician or advocate Identifies the forms of rejection of transgender people sanctioned by culture and provides suggestions for dealing with them Discusses the future of transgender people as well as that of the binary gender system in Western culture
