Diagnóstico prenatal. Realidad y esperanza

The bioethical problems connected with prenatal diagnosis have something to do with difference between diagnostic possibilities and therapeutics impossibilities. There are 3.500 genetic diseases, but only three or four of then can be cured at the present. The prenatal diagnosis is normal y designed to elirninate a malformated foetus. This behaviour reuces the malformated person to category of undesirable malformation. To inform rightly to parents is necessary a no-directive approach, because the language is a subtil tool which can produce big changes in the way of understanding the reality. The author, a well-known expert in bioethics, has his hope pinned on a use of biomedical techniques to service of life, and taht genetists anb obstetricians will be faithfull to principie Primum non nocere.
