The seventh World Summit of National Ethics Committees, which was held in Paris in 2008, has proved to be fruitful on two main levels. First of all, in face of the gradual development of manipulation techniques upon the elements of the human body, the international awareness of ethical stakes is getting more acute. The States are looking for common ground by bringing out some universal principles through their Ethics Committees. Secondly, even though those legal authorities manage to agree on fundamental values, they express divergences on the concrete way to implement them. Prenatal medicine and assisted reproduction reflect those discrepancies.
