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.
Sure there are religions, but I'm asking about the political movement. Are there strides from any parties attempting to ban abortion to also ban IVF?
The reason I'm asking is pretty simple - I believe that many, many people are simply "for births", and politicians capitalize on that. They won't go against IVF since it leads to more births, but they go against abortions because they lead to fewer. Do you have any evidence going against this?
