It's not "pro-life" to make 10 or 20 or 30 embryos so that one can survive until birth.
It's also not pro-life to convert human beings into manufactured products -- which is exactly where IVF tends to go -- in part because, inherent in the idea of a manufactured product, is the idea that you throw it away the "defective" ones.
IVF is not pro-life in any way, shape, or form.
Oh please, if the embryos are “defective” they would not have survived in the womb anyway and those that are not used can be donated to other childless couples. It is also a “manufactured product” when the egg meets the sperm normally and the defective ones don’t survive, so that point is moot as well.
