Embryo adoption is not a legal 'adoption' at all, at least in the sense of a traditional adoption which occurs after birth,' the National Embryo Donation Center says. (abc7chicago.com)
The American Society for Reproductive Medicine says, 'Application of the term 'adoption' to embryos is inaccurate, is misleading, and could place burdens upon recipients and should be avoided. (abc7chicago.com)
This paper will evaluate the morality of these four possible solutions, particularly frozen human embryo adoption in the light of the Magisterium of the Catholic Church, which in its Instruction Dignitas Personae, appears to have opted to consider this practice as illicit. (uchile.cl)
We also review the various stances of expert moralists in favour of or against frozen human embryo adoption, and we reflect on the extent to which the doctrine contained in Dignitas Personae can bind the moral conscience of the Catholic faithful. (uchile.cl)
Finally, we make a personal evaluation of frozen human embryo adoption, in an attempt to find moral reasons that substantiate the negative opinion manifested by the Catholic Magisterium on this matter. (uchile.cl)
In conclusion, we suggest that the moral assessment of frozen human embryo adoption as set forth in Dignitas Personae might not be considered as settled. (uchile.cl)

In the frozen embryo context, we have the possibility of another viability line, this one at an extremely early stage of embryonic development rather than at a relatively late stage of fetal progression. (dorfonlaw.org)
As in the later viability situation, someone arguing on behalf of a frozen embryo can say that the embryo is "viable" in the sense that it can survive without the conscription of an unwilling womb in its service. (dorfonlaw.org)
The viability of a frozen embryo is distinct from the viability of a late-term fetus in some ways, of course -- the latter can live without being inside any womb and the latter has also reached a developmental stage at which many more people would regard it as having rights (perhaps because it has by now become sentient).
