Observing the practical situation of the techniques of assisted procreation in European societies, one is allowed to affirm that these techniques are largely in use in our societies, it did not find resistance among the secular groups of the society. It is not the case of the representatives of the Catholic church, hostile to each intervention on the reproductive mechanisms as being a violation against natural law, the most virulent opposition is linked to intervention on embryos or to each way (...) of reproduction outside of the canonic marriage, considering therefore artificial insemination as immoral and anti-juridical.The opposition between secular and the catholic groups is of unequal intensity in the different European countries, it did not stop the application and the use of these reproductive techniques although it made the adoption difficult of measures in some states, and even in the European Parliament. However, they could not oppose the scientific and medical corporation and their arguments of treatment of diseases and of sterility of men or women. This way to present these reproductive techniques in terms of lowering of suffering of couples not able to reproduce naturally received a full social acceptance and legitimation, acceptation because the origin of these techniques is incontestably scientific and legitimation because the goal is essentially medical.
