Infertility and the suffering associated with it has always been a tragic part of the human experience. This is especially true today. Various medical remedies have been developed to deal with human infertility with artificial reproductive technologies being widely used. There are many treatments for infertility which are approved by the Catholic Church. But the use of in vitro fertilisation IVF and related technologies have been condemned as contrary to the natural moral law. This book porvides both an account of Church teaching and why the Church teaches what she does in a way that is accessible to the interested layperson. Dr John Fleming reflects on and amplifies this new teaching document of the Church to make it all the more accessible to those who ought to benefit from it not only those in the pew but also those in the laboratory who are not even religious.
