Provides the most up-to-date information on transgender science and its applications, for gender-diverse people, their supporters, and the professionals who assist them to lead healthy, happy, and successful lives.The number of people presenting at gender clinics worldwide for assistance has increased exponentially in the last decade. Transgender people also have become much more prominent in the media. An increase in political populism, however, has brought unprecedented attacks on trans* people. Covering a wealth of topics relevant to transgender people and their supporters, both social and professional, Heath and Wynne help readers to see through the flawed arguments of those who wish to inflict damage on the trans* community. The content of this book ranges from theoretical ideas about the origin of gender diversity to practical solutions for trans* people to enjoy life in their chosen gender. Physical health topics include hormone therapy, puberty blockers, breast augmentation/reduction, gender confirmation surgery, and speech therapy. Mental health topics include dealing with discrimination, bullying, and transphobia. The text is presented so that it can be understood with no scientific background, but is also highly relevant to the health professional. Copious footnotes and references allow those wishing to delve more deeply into the topics to do so easily. The book is also supported by readily accessible resources available online and on social media.
