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.
