When embarking on the journey of fertility treatments, many people hear the term “Frozen Embryo Transfer” or FET. This technique has become an increasingly popular option, providing more flexibility, control, and a higher chance of success for individuals undergoing in-vitro fertilization (IVF). At Nandi IVF, we frequently use FET to help couples realize their dreams of parenthood.
In this blog, we will take a closer look at what Frozen Embryo Transfer entails, how it works, its benefits, risks, and whether it’s the right option for you.
Frozen Embryo Transfer (FET) is a part of the IVF process where frozen embryos, which were either created in a previous IVF cycle or donated, are thawed and transferred into the uterus.
Embryos can be frozen at various stages of development—either at the cleavage stage (day 3) or blastocyst stage (day 5 or 6). Cryopreservation, or the freezing of embryos, allows couples to have multiple chances of pregnancy from a single IVF cycle.
The FET process involves several steps, including preparation of the uterus, thawing of embryos, and the actual transfer. Here’s a detailed breakdown of the process:
Before the embryos are transferred, the uterine lining must be prepared to ensure it is receptive. Hormone therapy is typically used to optimize the thickness of the endometrium.
The frozen embryos are carefully thawed on the day of the transfer. This is a delicate procedure where embryologists must ensure the viability of the embryos. The survival rate of frozen embryos after thawing is around 95%.
This is a relatively simple procedure that takes only a few minutes. Using a thin catheter, the embryos are placed into the uterus through the cervix. No anesthesia is required, and patients can typically return home shortly after the procedure.
After the transfer, a two-week wait ensues before a pregnancy test can be conducted to determine if the transfer was successful.
Frozen Embryo Transfer offers many benefits for couples seeking fertility treatment. Let’s explore some of the key advantages:
One of the most compelling reasons to consider FET is its higher success rate, especially when compared to fresh embryo transfers. Over the years, improvements in embryo freezing techniques, particularly vitrification (a rapid-freezing process), have contributed to better outcomes.
If you’ve undergone IVF and had multiple embryos created, FET allows you to save and use them for future attempts. This eliminates the need for repeated egg retrieval and hormone stimulation, which can be physically and emotionally taxing.
FET provides the flexibility to time the embryo transfer according to your schedule or your body’s readiness. If you’re not ready for immediate transfer after the initial IVF cycle, freezing the embryos gives you the freedom to wait until the conditions are optimal.
For women at risk of developing Ovarian Hyperstimulation Syndrome (OHSS) due to IVF medications, FET allows a safer alternative. In such cases, embryos can be frozen, and the transfer can take place after the body has recovered.
While FET offers many benefits, it’s important to understand that, like any medical procedure, it does come with some risks.
Though the vast majority of embryos survive the thawing process, there’s a small chance that some may not. Clinics like Nandi IVF use advanced techniques to minimize this risk, but it is something to consider when planning an FET.
Transferring more than one embryo increases the likelihood of multiple pregnancies (twins, triplets, etc.). While this may seem like a positive outcome, it also comes with risks, such as preterm birth or low birth weight. At Nandi IVF, we advise patients on the best number of embryos to transfer based on their individual circumstances.
As with any fertility treatment, FET can be emotionally challenging, especially during the waiting period between the transfer and the pregnancy test. It’s important to have a strong support system in place and to be prepared for various outcomes.
The decision to pursue FET depends on several factors, and the process is highly individualized. Here are some situations where FET might be the right choice:
If you’ve previously undergone IVF and have frozen embryos, FET allows you to use those embryos without needing another round of ovarian stimulation and egg retrieval.
For some women, especially those with high hormone levels or those at risk of OHSS, a fresh embryo transfer may not be ideal. Freezing the embryos and delaying the transfer until the body has recovered offers a safer alternative.
If you’re undergoing preimplantation genetic testing (PGT), the embryos will need to be frozen while the testing is carried out. After the results come back, only the healthy embryos are transferred.
Freezing embryos during your prime reproductive years can be an excellent option if you plan to delay pregnancy for personal or medical reasons. With FET, you can use the embryos in the future, giving you control over when you start your family.
