Embryo adoption is a very interesting moral grey area, and I realize the Church has not ruled definitively on it (although it has come close if
Dignitas Personae deems it morally problematic).
Here’s a few other problems that I see with it, though:
- If the practice of embryo adoption becomes widespread, it could encourage more couples to practice IVF if they know that there is a good chance that someone will adopt their “unused” embryos.
- There are thousands of children in the foster system in the U.S. (and in orphanages overseas) waiting for adoption. These children face very poor prospects if they do not find a permanent home and family before age 18. There are currently far more children waiting for a home than there are couples willing to adopt them. Shouldn’t these children receive first priority among couples considering adoption? Not everyone is called to adopt from the foster care system, but those considering adoption should at least prayerfully discern it, as the need is urgent. Frozen embryos stored from IVF do not yet have awareness, and while it is very wrong to create these little humans and keep them suspended in a freezer, it seems to me that given the choice between saving an embryo and a living child in need, one should choose the child.
Not that it has to be either/or; one could adopt both, but it seems that opening the door wide to embryo adoption would further reduce the number of families willing to adopt foster children.
