Frozen Embryo Transfer (FET)
Frozen embryo transfer (FET) has revolutionized reproductive medicine, allowing the uterus to return to a calm, receptive physiological state while enabling preimplantation genetic testing and future family building. Learn how FET maximizes implantation and pregnancy success at VCRM.

At our Virginia fertility center, we offer customized fertility solutions tailored to each patient's physiological profile and reproductive goals. Frozen embryo transfer (FET) is an evidence-backed technique that has dramatically improved pregnancy outcomes worldwide.
Couples and individuals who undergo an IVF cycle frequently freeze their healthy blastocysts using ultra-rapid vitrification. Frozen transfers yield success rates that are equal to—and often higher than—fresh transfers. Because the woman's body has time to recover from the supra-physiological hormone levels of ovarian stimulation, the uterine endometrium is in a far more natural, receptive environment when the embryo is placed.
State-of-the-art vitrification guarantees virtually no cellular freeze damage.
Freezing all embryos eliminates ovarian hyperstimulation syndrome risk.
Allows ample turnaround for comprehensive chromosomal genetic testing.
Key Benefits of the "Freeze-All" & FET Strategy
Opting for a frozen embryo transfer cycle provides distinct medical and family planning advantages:
1. Physiological Uterine Recovery
During ovarian stimulation, estrogen and progesterone levels rise to 10–20 times normal levels, which can advance the endometrial lining prematurely. Postponing transfer to a subsequent cycle allows hormones to normalize, ensuring optimal synchrony between embryo and endometrium.
2. Seamless Preimplantation Genetic Testing (PGT)
PGT-A and PGT-M genetic screening requires 7 to 14 days for DNA sequencing. Freezing blastocysts enables thorough chromosome analysis so only euploid embryos are selected for transfer.
3. Future Sibling Transfers Without New Stimulation
Patients can store surplus high-quality embryos for years. When you are ready to expand your family in the future, you can undergo a simple FET cycle without repeating ovarian stimulation or egg retrieval.
How Uterine Preparation Works for FET
For patients undergoing FET at our Virginia fertility center, treatment begins with an individualized protocol designed by Dr. Fady Sharara:
- Evaluating the Endometrium: The woman needs a trilaminar endometrial lining of sufficient thickness (> 7.5–8 mm) and optimal sub-endometrial vascularity to support implantation.
- Programmed (Hormone Replacement) Protocol: Oral or transdermal estrogen is administered to gently build the lining, followed by progesterone (intramuscular injections or suppositories) once the lining reaches optimal thickness.
- Natural or Modified Natural Cycle: For women with predictable ovulatory cycles, FET can be synchronized with natural ovulation and monitored with ultrasound and LH testing.
- Endometrial Receptivity Analysis (ERA): For patients with prior implantation failures, ERA testing identifies the exact personalized timing for progesterone exposure.
The Frozen Embryo Transfer Procedure
The FET procedure is gentle, painless, and performed in our comfortable procedure suite in Reston:
1. Embryo Thaw
Our expert embryology team thaws the selected blastocyst in specialized warming solutions and assesses its re-expansion.
2. Ultrasound Guidance
Dr. Sharara uses high-resolution transabdominal ultrasound to visualize the exact catheter path through the cervix into the uterine cavity.
3. Gentle Placement
The embryo is softly deposited 1–2 cm from the uterine fundus. Patients rest briefly on the procedure table and resume normal activities that day.
FET Success Rates at VCRM
Because of our advanced Class 100 cleanroom laboratory, ultra-rapid vitrification systems, and Dr. Sharara's personalized uterine preparation protocols, VCRM's FET success rates consistently outperform national averages across all age categories.

Frequently Asked Questions About Frozen Embryo Transfer
Does freezing damage the embryos?
No. With modern vitrification (ultra-rapid flash freezing), ice crystal formation is completely eliminated. At VCRM, over 98% of cryopreserved blastocysts survive the thaw intact with full implantation potential.
How long can embryos stay frozen?
Embryos remain safely cryopreserved in liquid nitrogen at -196°C indefinitely. Healthy babies have been born from embryos stored for more than 15 to 20 years with no increase in health or developmental risks.
Is anesthesia required for a frozen embryo transfer?
No. The FET procedure feels very similar to a routine Pap smear and takes only 5 to 10 minutes. Anesthesia is not needed, and you can walk out of the clinic shortly after the transfer.
