Book excerpt: Through the lens of psychoanalytic thought about sexuality, the book examines changes in the area of procreation and generation, the disjunction between sexuality and procreation introduced by biotechnology and some new methods of reproduction, and their impact on the essential moments of existence (birth, illness, death) and the most intimate aspects of personal identity (sexuality, procreation, body). At the centre of this book is the thesis that the disjunction between sexuality and procreation brought about by biotechnology represents a new scenario and introduces elements of discontinuity. What kind of effects on individuals will the modifications introduced by biotechnologies in the field of procreation have? How can these changes affect even the most profound aspects of personal identity, including body and sexuality? How might they interfere with the sphere of desire? The book investigates the new scenarios and the consequences which are emerging, such as an alteration of personal boundaries, both in spatial and temporal terms, which is reflected in our way of thinking about ourselves and our relationships and the assertion of an unconscious fantasy that the limits imposed by sexuality and death can be surpassed. Offering a psychoanalytic reading of changes introduced in this field, this book will appeal to training and practising psychoanalysts, as well as philosophers, psychologists and gynaecologists.
