Sexual health is now seen as multi-dimensional, a product of complex interplay between biological, psychological, and socio-cultural factors. This book brings together 34 expert Australian practitioners and researchers to provide a comprehensive, authoritative, up-to-date, and stimulating perspective on sexual health. In numerous and significant ways the book differs from its predecessor-volume, published in 2005. Chapters are now grouped in to five parts:  Sexual health in Australia;  Foundations for sexual health;  Sexual health in clinical practice;  Sexual health in specific populations; and  Prevention and promotion. All original chapters have been thoroughly reviewed and updated. Six new chapters are included, on:  Sexual health in society;  Contraception, and options for unintended pregnancy;  The legal environment of sexual healthcare practice;  Lesbian, gay, bisexual, and transgender people;  Health promotion; and  Prevention strategies. Chapters on sexual health in adolescence and in older adults have been expanded. A section on refugees is now included (with sections on homeless youth, sex workers, and prisoners) in a chapter on the sexual health of 'other vulnerable populations'. This book is one-third longer than its predecessor-volume. For tertiary-level students of nursing, medicine, public health, health promotion, and sexology, this new book will continue to be an ideal textbook. For healthcare practitioners working in reproductive health, sexual health, maternal and child health, and many other specialist fields, it will be an invaluable first reference.
