During these months this section is devoted to excerpts from the Church's document on certain issues concerning procreation 2008). With new research and procedures, it is most important to be informed and to know the moral dimensions. Here is part 6.

15. ......Embryos produced in vitro which have defects are directly discarded. Cases are becoming ever more prevalent in which couples who have no fertility problems are using artificial means of procreation in order to engage in genetic selection of their offspring. In many countries, it is now common to stimulate ovulation so as to obtain a large number of oocytes which are then fertilized. Of these, some are transferred into the woman's uterus, while the others are frozen for future use. The reason for multiple transfer is to increase the probability that at least one embryo will implant in the uterus. In this technique, therefore, the number of embryos transferred is greater than the single child desired, in the expectation that some embryos will be lost and multiple pregnancy may not occur. In this way, the practice of multiple embryo transfer implies a purely utilitarian treatment of embryos. One is struck by the fact that, in any other area of medicine, ordinary professional ethics and the healthcare authorities themselves would never allow a medical procedure which involved such a high number of failures and fatalities. In fact, techniques of in vitro fertilization are accepted based on the presupposition that the individual embryo is not deserving of full respect in the presence of the competing desire for offspring which must be satisfied.
This sad reality, which often goes unmentioned, is truly deplorable: the "various techniques of artificial reproduction, which would seem to be at the service of life and which are frequently used with this intention, actually open the door to new threats against life".
