What Is Embryo Banking?
Embryo banking is the practice of completing multiple IVF retrieval cycles and freezing all resulting embryos before attempting any transfers.
How Embryo Banking Works
Instead of transferring embryos after a single retrieval, patients undergo two or more retrieval cycles and accumulate frozen embryos. All embryos may be tested with PGT before any transfer. This approach builds a larger cohort of embryos to increase the cumulative chance of live birth.
When Embryo Banking Is Used
Embryo banking is most common for patients over 37 who are expected to produce fewer euploid embryos per cycle. It is also used for patients planning multiple children and for intended parents working with a gestational carrier who want to minimize the number of transfer cycles.
Why It Matters in IVF
Embryo banking improves cumulative success rates by increasing the total number of embryos available for transfer. It separates the retrieval phase from the transfer phase, allowing more flexibility in timing.
