A 50-60% chence of taking home a baby from the hospital would be a reasonable expectation, if the following criteria are met:
1. There is realitively synchronous growth of the donor's follicles during the stimulation and the E2 is appropriate at the time of hCG (about 250 pg/ml for each mature follicle)
2. The donor provides 12-20 eggs and is NOT shared between two or more recipents
3. About 80% of the eggs are mature at the time of retrieval.
4. About 80% of mature eggs fertilize normally (one sperm - one egg)
5. About 50% of the resulting embryos make it to the blastocyst stage
6. Two high quality blastocyst stage embryos are transferred and any remaining embryos cryopreserved.
You can see there's a lot of "ifs" above and a lot of things have to go just right to get in the 50-60% of the couples that are successful from DEIVF. However, in a good program (i.e. one with a consistent 50-60% live birth rate from DEIVF), you can be confident that all these factors are being controlled as best they can. You can't control everything and sh** happens.
DEIVF provides the best chances of pregnancy for all ART treatments. Its expensive, but from a strictly financial viewpoint, its the best "bang for the buck".
A word about superlatives and IVF. I realize you were poking fun with all the superlatives in your post and I'm glad you made that point. Sometimes docs use supleratives, as you did above, and give patients a false sense of security and then, when sh** happens, the world caves in. It is important to maintain a realistic outlook, ever when you are bombarded with superlatives from docs and nurses. I probably don't have say much more about that on this board. Patients wouldn't be here if the superlatives turned out to be true.
