In Vitro Fertilization (IVF)

Embryo Freezing

In almost all IVF cycles, the number of embryos which are produced is more than the number which are actually transferred. In these cycles, it may be desirable to cryopreserve (freeze) these "extra" embryos, provided that they are of high enough quality.

Such frozen embryos have a very good chance of success in subsequent treatment cycles, and enable many couples to conceive on multiple occasions from one IVF egg retrieval, since frozen embryo cycles do not require the time or expense of additional fertility medications, egg harvestings, or laboratory procedures.
