Answers to common questions about Frozen Embryo Transfers to increase your chances of conception
Frozen Embryo Transfer (FET)
A Frozen Embryo Transfer (FET) is a cycle during which frozen embryos from a previous fresh in vitro fertilization cycle (or donor egg cycle) are thawed and then transferred into a woman’s uterus.
Why Choose Frozen Embryo Transfer
Frozen Embryo Transfer (FET) has been shown to increase implantation rates and improve obstetrical outcomes. FET is also considered a healthier implantation process because it allows for a better connection between the placenta and the mother. In addition, frozen cycles, versus fresh transfer cycles, show higher birth weight deliveries and lower risk of prematurity.
FET also allows for optimal timing and a more natural transfer experience since the embryo can be cryopreserved or “frozen” until your hormone levels return to a more natural, receptive state, usually on their next cycle.
Preparing for Frozen Embryo Transfer
Preparation for a FET involves blood tests and ultrasound monitoring so that an optimal time for implantation can be established. In some cases, you may also be given hormone medications in order to increase the chances of conception.
FET is an outpatient procedure that does not require sedation. After the transfer is completed, there is minimal downtime, discomfort, or side effects. Frozen embryos remain viable for well over ten years, so you may schedule implantation whenever the timing and conditions feel right.
Frozen Embryo Transfer Success Rates
Based on published data and large trials from RMA and other fertility programs around the world, RMA has now made Frozen Embryo Transfer (FET) a standard of care for all patients undergoing IVF.
And now, with Pre-Implantation Genetic Testing for Aneuploidy (PGT-A), RMA doctors can identify the healthiest embryos for transfer in advance of implantation. Embryos that are imbalanced, with too few or too many chromosomes, often result in a failed IVF cycle or miscarriage. RMA only uses Juno Genetics for embryonic screening.
Frequently Asked Questions About Frozen Embryo Transfer (FET)
Frozen Embryo Transfer (FET) is a procedure in which a previously frozen embryo is thawed and transferred to the uterus. FET allows patients to use embryos from prior IVF cycles, increasing flexibility in family planning.
FET provides patients the option to space out pregnancies, reduces the need for additional egg retrieval procedures, and allows time for genetic testing on embryos if desired.
The FET procedure involves carefully thawing a frozen embryo and then transferring it into the prepared uterus. This procedure requires hormonal preparation to ensure the uterine lining is optimal for embryo implantation.
Candidates for FET include those with previously frozen embryos, individuals who wish to delay pregnancy after an IVF cycle, or patients who want to avoid multiple fresh cycles. FET can be particularly beneficial for women undergoing genetic testing.
FET is generally safe, but as with any procedure, there are some risks, including a small chance of embryo loss during thawing. However, advancements in cryopreservation techniques have significantly reduced these risks.
