Frozen Embryo Transfer


Timing is key, and knowledge is power.

Frozen Embryo Transfer (FET), which is when embryos are frozen until doctors are ready to transfer them into the woman’s uterus, are done for two reasons. First, they preserve embryos while chromosomal testing is performed, and second, they allow embryos to be placed back inside the uterus when it is ready to receive the embryo.

Like lock and key.

Not only have FET’s shown to increase implantation rates, but they have also resulted in improved obstetrical outcomes.


Frozen Embryo Transfer

Based on published data and large trials from our sister practice, RMANJ and other fertility programs around the world, Reproductive Medicine Associates of Northern California has made Frozen Embryo Transfer (FET) a standard of care for all patients undergoing IVF.

Fresh VS Frozen

In addition to showing an increase implantation rates, FET has shown to improve obstetrical outcomes including higher birth weight deliveries and lower risk of prematurity over fresh transfer cycles.

Timing Is Everything

FET usage allows a more natural transfer experience by safely cryopreserving, or “freezing,” the embryo and waiting until the patient’s hormone levels return to a more natural state to receive the embryo, usually on their next cycle.

Evidence Based

FETs have been Reproductive Medicine Associates of Northern California’s recommended method of embryo transfer.
