On your profile you state “Every child conceived has a right to be born”. By definition rights don’t require actions by someone else. So if an embryo is fertilized envitro, how is that “right” excercised without requiring an action on the part of a woman to be implanted? There are untold thousands of frozen embryos out there. How would you ensure their “right” to be born?
There’s no way on earth to ensure this God-given right in the instances which you mention.
We have to rely on the fallible consciences of imperfect men and women.
