My understanding is that studies in the past 3 years of so indicate that success rates for frozen eggs now rival fresh eggs, because of advances in cryopreservation. This is the same situation as frozen embryos - ie chances of a successful thaw are now better for FET because of freezing methods.
However this assumes the use of the latest technology to freeze the eggs. If your friend had the eggs frozen recently by a top grade IVF firm using the best available technology then she has a similar chance; if however the eggs were frozen some years ago, the chances may be reduced somewhat depending on what technology was used.
