The most controversial issue
Steptoe and Edwards achieved the first full-term pregnancy from an embryo obtained by in vitro fertilization. They had previously made a large, though undetermined, number of unsuccessful attempts issue . There is no issue that has raised more controversy in the no longer short history of bioethics than in vitro fertilization techniques. They provoke very intense feelings of acceptance and rejection. And this affects moralists and people in the street as much as scientists. It is very difficult to be impartial and goal. Researchers and specialists select and interpret data according to their convenience. For example, they keep telling us a story of the first 14 days of the embryo, woven of assumptions and voluntarism. It is understandable that this is the case, since this problem touches the most intimate core of what is human. The Nobel Prize to Edwards will not solve it.
In my opinion, until today no one has seriously refuted, with rational arguments and data contrasted, the ethical reasons contained in the declaration "Donum vitae", a work that carries the signature of Cardinal Ratzinger.
Fortunately, children do not present serious problems, even if, with some frequency, they manifest annoying but not serious disorders. As they are closely followed up on their development, in case serious malformations appear, they are usually aborted. This improves the statistics. On the other hand, it seems that the internship has been imposed to reduce the high rate of twins years ago, a matter that caused many problems.
