If you're looking for Anti arguments:
The religious perspective as put forward by morningpaper - if life begins at conception then, in many cases, you are deliberately causing embryos to be created which will not be emplanted. True, many will not be of good enough quality to divide sufficiently successfully for freezing and later implantation, but there is still an element of playing God in that at various stages you have to make choices. You can only put back 2 (exceptionally 3) embryos at a time. The remaining embryos have a much lower chance of fulfilling their potential. There is also the issue of selecting "the best" embryos at this stage - is this one where we should have this ability? Some christians (and muslims as noted above) don't necessarily believe that the spiritual life begins at the moment of conception, though this is the RC (and often evangelical) standpoint.
Another anti argument is "why, given the surplus of children looking for a home, don't you adopt? Aren't you being selfish". Usually this is cited by people who know little about the realities of adoption at present, and of course the argument holds for all parents, not just the infertile.
Funding is clearly still an issue for many. Given how much children cost once they are born, shouldn't those couples, presumably both earning, fund their own family. And as misdee pointed out there are many more urgent areas where funding would be needed.
There is also the "nature" issue - perhaps infertility is nature's method of natural selection, and some people just shouldn't be parents.
Another argument is that by opening the door to this advance, where does it stop? Can we simply start to select characteristics of our children? Can we artificially delay parenthood into our 50s and 60s. How can we control what people do with this?
I think that the religious argument is in some ways the hardest - here it is just a different belief system. I know there has been some work in this area to come up with methods where only sufficent embryos are created which can then be implanted (is no surplus embryos are created). Haven't read the last RC document on this though, so there may still be other issues unaddresses.
