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. 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.
