Reciprocal IVF/ Egg Retrieval Advice! *Research*

I am looking for some advice please!

Myself and my partner are undergoing Reciprocal IVF (my eggs and she will carry). On the day of the puncture/ retrieval, they retrieved 29 viable eggs from me which seemed to shock the doctor. We decided to fertilize 17 of these as we understand that the success rate can be 30-50%.

The part shocking us is:

• On day 1, all 17 (100%) were successfully fertilized.
• On day 2, all 17 (100%) were successfully dividing.
• On day 3, all 17 (100%) are still successfully dividing/ developing.

There are roughly 2-3 days left.

Now we’re confused as these results seem quite high and 17 embryos is a lot, we knew this was a possibility but it’s still quite shocking (we know how lucky we are to have these results at this point and we are, of course, grateful). Does anybody have similar experiences or any advice please?
