What is Frozen Embryo Transfer (FET)?
Frozen Embryo Transfer (FET) is a revolutionary fertility treatment that allows individuals and couples to achieve their dreams of parenthood with flexibility and precision. This process involves thawing a previously cryopreserved or frozen embryo and transferring it into the uterus to establish a pregnancy. FET is a cornerstone of modern assisted reproductive technology (ART), empowering patients to pursue parenthood on their terms.
The benefits of FET include:
- Higher Success Rates: Innovations like vitrification (a rapid freezing process) have significantly increased embryo survival and live birth rates.
- Flexibility: FET allows you to plan transfers at the optimal time for your health and schedule.
- Cost Savings: By cryopreserving embryos during an initial cycle, you can avoid multiple egg retrieval procedures, reducing overall treatment costs.
At Kindbody, we specialize in providing personalized care, helping you navigate the emotional, physical, and financial aspects of your fertility journey.
The FET Process Step-by-Step
Navigating FET can feel overwhelming, but understanding each step can make the process smoother and less intimidating. Here’s what you can expect during an FET cycle:
1. Preparation and Baseline Testing
The first step involves evaluating your body’s readiness for an embryo transfer. Blood tests and ultrasounds are used to assess hormone levels and ensure the uterine lining is prepared for implantation.
Why is this important? A healthy uterine lining (endometrium) is essential for a successful embryo transfer.
What to expect: These tests are minimally invasive and take place during your initial consultation or at the start of your cycle.
2. Cycle Synchronization (aka Syncing)
Depending on your body and medical history, your doctor may recommend one of two approaches:
- Natural Cycle FET: This approach leverages your natural ovulation, with no hormonal preparation required.
- Hormone-Controlled Cycle FET: Estrogen and progesterone are administered to create an optimal uterine environment for the embryo.
Your Kindbody care team will guide you through this decision, tailoring your protocol to meet your unique needs.
3. Frozen Embryo Thawing
When it’s time for the transfer, your cryopreserved embryo is thawed in our state-of-the-art lab. Embryologists monitor the embryo’s viability before proceeding.
4. Embryo Transfer Procedure
The embryo is carefully placed into the uterus using a thin catheter. This quick, minimally invasive procedure typically doesn’t require anesthesia and takes only a few minutes.
5. Post-Transfer Care
After the transfer, you’ll receive detailed instructions to support implantation, including any necessary medications like progesterone. Rest assured, we’ll be with you every step of the way, ensuring you feel supported and informed.
FET Calendar: Timeline at a Glance
A typical FET cycle takes about 4–6 weeks. Below is a detailed look at each stage:
- Weeks 1-2: Baseline Tests and Cycle Preparation
During this phase, your care team conducts initial evaluations, including ultrasounds and bloodwork, to confirm that your body is ready to start the cycle.
- Weeks 3-4: Hormonal Therapy and Monitoring
If you’re undergoing a hormone-controlled cycle, you’ll begin taking medications like estrogen to prepare the uterine lining for implantation. Regular monitoring appointments ensure the lining is thickening as expected.
- Week 5: Embryo Thawing and Transfer
Your embryo is thawed and transferred into your uterus during a quick and minimally invasive procedure.
- Week 6: Pregnancy Test and Follow-Up
Approximately 9–12 days after your transfer, you’ll return for a blood test (beta hCG) to confirm pregnancy. If positive, we’ll schedule follow-up appointments to ensure everything is progressing smoothly.
Who is a Good Candidate for FET?
FET is a versatile treatment option for many individuals, including:
- Those with Cryopreserved Embryos: If you’ve undergone IVF in the past and have frozen embryos, FET offers a chance to build your family without additional egg retrievals.
- Patients with Specific Medical Conditions: FET is ideal for those with conditions like endometriosis, polycystic ovary syndrome (PCOS), or unexplained infertility.
- Fertility Preservation Patients: If you’ve preserved embryos before undergoing cancer treatments or other life events, FET allows you to pursue parenthood when the time is right.
At Kindbody, we work closely with every patient to create a plan that aligns with their unique circumstances and goals.
Success Rates and Factors Affecting FET Outcomes
Several factors influence the success of a frozen embryo transfer, including:
- Embryo Quality: Higher-grade embryos often yield better outcomes.
- Maternal Age: Younger patients typically experience higher success rates.
- Uterine Environment: Optimal preparation of the endometrium is crucial.
Kindbody leverages state-of-the-art technology and evidence-based practices to maximize your chances of success.

| Day | Activity | Details |
| Day 1 | Baseline Ultrasound & Bloodwork | Tests to confirm your uterine lining and hormone levels are ready to begin the cycle. |
| Days 3-10 | Start Estrogen | Oral, patch, or injection forms to prepare the endometrium for implantation. |
| Day 11 | Monitoring Appointment | Ultrasound and bloodwork to evaluate uterine lining thickness. |
| Day 14 | Begin Progesterone | Progesterone injections start to support implantation and early pregnancy. |
| Day 19 | Embryo Transfer Day | The frozen embryo is thawed and transferred into the uterus. |
| Day 28 | Pregnancy Test | Blood test (beta hCG) to determine if implantation was successful. |
This calendar is a general guide, and your specific treatment plan may vary based on individual needs and medical history.
Medications and Monitoring in Detail
The FET calendar includes medications like estrogen and progesterone, which are critical for preparing the uterine lining and supporting implantation.
Estrogen
- Taken in pill, patch, or injectable form.
