In response to growing demand, the thoughts and theories of the internationally acclaimed fertility specialist Dr Alan Beer have been documented. Is Your Body Baby-Friendly? explains for the first time ever why infertility, IVF failures and recurrent miscarriages happen. Even today, the cause of a majority of pregnancy complications (including premature delivery and stillbirth) in addition to IVF failure and infertility are labeled "unexplained." Dr Alan Beer has identified five categories of immune problem that can cause pregnancy loss, IVF failure and infertility. The logic behind the theories is considered, following an overview of how the immune system functions and why imbalances within it can affect pregnancy outcome. Since he began his pioneering tests and immune therapies over 30 years ago, Dr Beer has collaborated long-distance with fertility doctors, ob/gyns and REs across the world to help over 7,000 couples and achieved a pregnancy success rate of more than 85% within three natural cycles or IVF attempts. The book explains how the immune system can behave in a way that prevents a pregnancy from continuing. High levels of Natural Killer cells, genetic compatibility between partners and blood clotting problems are all significant causes of reproductive failure. Autoimmunity that can be inherited or environmentally triggered are a major reason for the increase in infertility and miscarriage today. This book also explains why such disorders are not just devastating to a pregnancy - they can also be markers of potentially serious health problems in the mother. This thoroughly researched and referenced text includes contributions from world-leading professionals, including Professor David Clark, Dr Carolyn Coulam, Dr William Matzner and Dr Geoffrey Sher. Best-selling author Zita West has also contributed a special chapter on holistic therapies and diet specifically for those with immune-based infertility and recurrent miscarriage. Dr Christo Zouves, author of "Expecting Miracles," who has worked with Dr Beer for over 15 years, has provided the Foreword.
