Then why is there no large-scale moral outcry over IVF? The process creates and discards a number of fertilized eggs, each of which has unique DNA. Isn't that the much more pressing issue, both considering the procedure is never medically necessary for survival of the woman, and considering that the embryos are created in the knowledge only few will develop into a full human?
Not sure how you define large scale but there are religions who do have a moral objection or at least rules around Ivf. As an example for Catholics each embryo must be treated as sacred and respected as human life. If you have extra embryos you must do everything possible to respect that life (ie transfer the embryos to someone in need and/or keep in cryo until that can happen). These rules aren’t typically known because ivf is a small minority of people that actually go through the process.
