Resumen: The aim of this article is to investigate whether techniques used for artificial reproduction safeguard or promote the future child¿s welfare, and whether they are capable of offering potential future children the best possible chance for the best life, in keeping with guidelines derived from the Principle of Procreative Beneficence. This analysis will be important for discerning the parental responsibility of couples or single reproducers who plan to use or have used any of these techniques, and also for those who defend the Principle of Procreative Beneficence, which implicitly entails the use of techniques of assisted human reproduction. The paper concludes that prospective parents should be informed not only of the specific level of risk and potential damages associated with each IVF technique, but also of the fact that given the available evidence none of the standard IVF techniques can be considered to be risk free, there is reason to believe that none of these techniques can be reconciled with the responsibility of prospective parents to the promote welfare of future children and/or to offer them the best possible life.
