why would you have frozen eggs? with IVF, they will remove your wife's eggs, then fertilize them with your sperm. Then they will transfer however many embryos you and your RE decide on. If there are left over embryos you can freeze them and implant them later. IVF doesn't always work. Lots of women here have gotten pregnant via FET (frozen embryo transfer). If you have all the children you want and still have left over embryos, you can either donate them to another infertile couple to give them a chance at life, donate them for research (these donations help improve techniques for IVF/FET), or just choose to destroy them. If your wife is older (not sure age cut off here), you might not even have left over eggs.
I suggest you write up a list of what you refuse to do because of religious or whatever reasons and have your wife do the same with what she wants/refuses to do. Then meet with your RE to go over your concerns.
I hope you and your DW can work this out.
