>>There is absolutely no need to kill anything with IVF. Ever. The whole point of IVF is to make life.<<
But it’s happening. Those babies who never make it out of the freezer and those who are implanted and are the second or third when the parents only wanted one.
If this was one embryo was made and one baby was born, it’s wouldn’t be a problem.
The problem is that IVF is to make life, but only the strong survive.
But “only the strong survive” with natural procreation too.
In a natural pregnancy, many, many naturally fertilized embryos fail to implant or grow further, and many, many fetuses miscarry naturally. Nature is imperfect and there is a lot of attrition.
IVF is no different.
Not every fertilized egg makes it to a live birth, whether with natural or IVF pregnancies.
