Approximately one in twenty men have sperm counts low enough to impair fertility but little progress has been made in answering fundamental questions in andrology or in developing new diagnostic tools or management strategies in infertile men. Many of these problems increase with age, leading to a growing population of men seeking help. To address this, there is a strong movement towards integrating male reproductive and sexual healthcare involving clinicians such as andrologists, urologists, endocrinologists and counselors. This book will emphasize this integrated approach to male reproductive and sexual health throughout the lifespan. Practical advice on how to perform both clinical and laboratory evaluations of infertile men is given, as well as a variety of methods for medically and surgically managing common issues. This text ties together the three major pillars of clinical andrology: clinical care, the andrology laboratory, and translational research.
