Excerpt from the Church's document on certain issues regarding procreation, Dignitas Personae: On Certain Bioethical Questions (September 2008). With new research and procedures, it is most important to be informed and to know the moral dimensions. Here is part 8.

Such a relationship of domination is in itself contrary to the dignity and equality that must be common to parents and children. ......

Cryopreservation is incompatible with the respect owed to human embryos; it presupposes their production in vitro; it exposes them to the serious risk of death or physical harm, since a high percentage does not survive the process of freezing and thawing; it deprives them at least temporarily of maternal reception and gestation; it places them in a situation in which they are susceptible to further offense and manipulation.
The majority of embryos that are not used remain "orphans". Their parents do not ask for them and at times all trace of the parents is lost. This is why there are thousands upon thousands of frozen embryos in almost all countries where in vitro fertilization takes place.
