Even if all the embryos could always be saved, IVF would still be unethical, for other reasons.

What other reasons?

[adiaireton8]

Even if all the embryos could always be saved, IVF would still be unethical for these reasons:

First, procreation should not be separated from the conjugal act. To do so is to treat human procreation as something less than it is.

Second, the unitive aspect of human procreation is not to be separated from biological reproduction. Such a separation is contrary to what human reproduction is by its very nature.

Third, no human should be produced or manufactured by technology. Such treatment is contrary to the dignity proper to humans by their very nature. (This is also the reason why human cloning is unethical.) The use of technologies that supplant the natural process of human reproduction inherently treat the child as a mere artifact, which is to treat the child contrary to what he or she is.
