freeze-all strategy
IVF approach where all viable embryos are cryopreserved rather than transferred fresh.
Full Definition
A freeze-all strategy involves cryopreserving all viable embryos from an IVF cycle instead of proceeding with fresh embryo transfer, with subsequent transfer occurring in a later, unstimulated cycle. This approach allows optimization of endometrial receptivity, reduces OHSS risk, permits comprehensive genetic testing, and may improve overall pregnancy rates in certain patient populations. The strategy has become increasingly popular with advances in vitrification technology that achieve excellent embryo survival rates.
Usage
Usage note: Strategic decision affecting entire cycle management; increasingly common in modern IVF.
