If you are asking about her chances of successful pregnancy, it is good. No doctor will implant all 7 embryos at the same time but they will pick the best combination of 2 or 3 for immediate transfer, then freeze the rest for future cycles. There is a good chance that at least one out of those seven eggs will stick (whether it be in the first fresh cycle or in a subsequent cycle where frozen embryos are thawed and transferred), but a lot will depend on her fertility history (why does need IVF in the first place?).
