Frozen Embryo Transfer (FET)

Frozen embryo transfer is a crucial aspect of modern fertility treatment, offering patients flexibility and increased chances of success in achieving pregnancy. At Advanced Fertility Center of Chicago, we provide expert care and cutting-edge technology to ensure the highest success rates with FET.

What is Frozen Embryo Transfer (FET)?

Frozen embryo transfer (FET) is a process where previously frozen embryos, created during an earlier in vitro fertilization (IVF) cycle, are thawed and transferred into the uterus. This procedure allows patients to use their frozen embryos in a subsequent cycle, which can be months or even years after the embryos were initially created.

When is FET Recommended?

FET is recommended in several scenarios, including:

  • Pre-implantation Genetic Testing (PGT): After embryos are tested for genetic abnormalities and the healthiest ones are selected, they can be frozen and transferred later.

  • Risk of Ovarian Hyperstimulation Syndrome (OHSS): For patients at risk of OHSS due to hormone stimulation, freezing embryos allows for a safer, more controlled transfer process once the body has recovered.

  • Fertility Preservation: For those undergoing medical treatments, like chemotherapy, or for personal reasons, freezing embryos offers the chance to conceive later.

  • Optimal Uterine Environment: Sometimes, the uterus may not be ready for immediate implantation. FET allows time for preparing the uterine lining to ensure a higher likelihood of successful implantation.

  • Family Planning Flexibility: FET enables patients to expand their family at a later date without undergoing another full IVF cycle.

The Role of Vitrification in FET

At Advanced Fertility Center of Chicago, we use a process called vitrification to freeze embryos. Vitrification is a rapid freezing technique that prevents the formation of ice crystals, which can damage the embryos. By cooling the embryos at an extremely fast rate, vitrification ensures that they are preserved in a highly stable state, maintaining their viability and quality for future use. This advanced technique significantly enhances the success rates of FET by ensuring that the embryos remain as healthy as possible when thawed.

Factors Contributing to the Success of FET

Several factors contribute to the success of FET:

  • Embryo Quality: The health and quality of the embryos at the time of freezing play a significant role in the success of FET. Higher-quality embryos are more likely to survive the thawing process and successfully implant in the uterus.

  • Uterine Lining Preparation: A well-prepared uterine lining is crucial for successful implantation. Hormonal treatments are often used to ensure that the lining is thick enough to support the embryo.

  • Age of the Patient: The age of the patient when the embryos were created can influence the success rate. Younger patients tend to have higher success rates due to better egg quality.

  • Thawing Process: The expertise of the embryology team in thawing the embryos is vital. At Advanced Fertility Center of Chicago, our highly skilled embryologists use the latest techniques to maximize the viability of thawed embryos.

  • Timing of the Transfer: The timing of the embryo transfer in relation to the patient’s menstrual cycle is critical. Ensuring that the transfer aligns with the optimal window for implantation can significantly improve success rates.

  • Overall Health and Lifestyle: A patient’s overall health, including factors such as weight, smoking, and stress levels, can also affect the success of FET. Maintaining a healthy lifestyle and following medical advice can increase the chances of a successful pregnancy.

The FET Process at Advanced Fertility Center of Chicago

  1. Thawing the Embryos: Our skilled embryologists carefully thaw the vitrified embryos using state-of-the-art techniques to maintain their viability.

  2. Preparing the Uterine Lining: To maximize the chances of a successful pregnancy, we prepare the uterine lining with hormones, ensuring it is optimal for embryo implantation.

  3. Embryo Transfer: Once the uterus is ready, the thawed embryo(s) are gently transferred into the uterus using a catheter, a process that is quick and typically painless.

  4. Post-Transfer Care: After the transfer, we provide personalized guidance and support to enhance the chances of implantation and a successful pregnancy.
