This narrative follows the lives of a group of transgendered prostitutes ("travestis" in Portuguese) in the Brazilian city Salvador. Travestis are males who, at an age as young as ten, adopt female names, clothing styles, hairstyles and linguistic pronouns. They ingest massive doses of female hormones and inject litres of industrial silicone into their bodies to create breasts, wide hips and large thighs and buttocks. However, no travesti identifies herself as a woman, moreover they regard any male that does so as mentally disturbed. The text analyzes the ways that travestis modify their bodies, explores the motivations that lead them to choose this particular gendered identity, and examines the complex relationships that they maintain with one another, their boyfriends and their families. Also examining how they earn their living through prostitution and discussing the reasons that prostitution for most travestis is a positive and affirmative experience. Arguing that transgenderism never occurs in a natural or arbitrary form, the text shows how it is created in specific social contexts and assumes specific social forms, suggesting that travestis may distill and perfect the messages that give meaning to gender throughout Brazilian society and possibly throughout much of Latin America.

Within twenty, maybe forty, years most people in developed countries will stop having sex for the purpose of reproduction. Instead, prospective parents will be told as much as they wish to know about the genetic makeup of dozens of embryos, and they will pick one or two for implantation, gestation, and birth. And it will be safe, lawful, and free. In this work of prophetic scholarship, Henry T. Greely explains the revolutionary biological technologies that make this future a seeming inevitability and sets out the deep ethical and legal challenges humanity faces as a result.
“Readers looking for a more in-depth analysis of human genome modifications and reproductive technologies and their legal and ethical implications should strongly consider picking up Greely’s The End of Sex and the Future of Human Reproduction…[It has] the potential to empower readers to make informed decisions about the implementation of advancements in genetics technologies.”

“[Greely] provides an extraordinarily sophisticated analysis of the practical, political, legal, and ethical implications of the new world of human reproduction. His book is a model of highly informed, rigorous, thought-provoking speculation about an immensely important topic.”
