You have made it through the daily hormone injections, the egg retrieval, and the stressful days of waiting for updates from the embryology lab. You finally have a healthy, developing embryo. The embryo transfer is the final clinical step of the IVF process. It is the moment we carefully place that embryo into your uterus so it can implant and grow.
Despite being the most important milestone, the embryo transfer is actually the fastest and easiest part of the entire IVF cycle physically. There is no anesthesia, no surgery, and no pain.
Fresh vs. Frozen: Which is Better?
Depending on your specific cycle, Dr. Lakshmi Priya will recommend either a Fresh Embryo Transfer or a Frozen Embryo Transfer (FET).
- Fresh Transfer: This happens 3 to 5 days after your egg retrieval. We take an embryo that has just finished developing in the lab and transfer it immediately. This is usually recommended if your hormone levels remain stable after the retrieval and your uterine lining looks receptive.
- Frozen Transfer (FET): This is becoming the most common and successful approach. IVF stimulation medications push your hormones to artificially high levels, which can sometimes make the uterine lining less receptive to a newly implanted embryo. By flash-freezing the embryo, we allow your body a full month to rest and recover. In your next cycle, we can precisely control the preparation of your uterine lining, ensuring the “soil” is perfectly ready for the “seed.”
How Do We Choose Which Embryo to Transfer?
If you have multiple embryos, our senior embryologist evaluates them to select the one with the highest chance of resulting in a healthy baby. We look at two main factors:
- Visual Grading: We evaluate how the cells are dividing. An embryo that is expanding well and has tightly packed inner cells gets a higher grade.
- Genetic Testing (PGT-A): If you opted for genetic testing, we already know the exact chromosomal makeup of each frozen embryo. We will only transfer an embryo that has the correct number of chromosomes, which drastically reduces the risk of miscarriage and IVF failure.
The Procedure: What to Expect on Transfer Day
You will be awake and alert for the entire process. In fact, many patients bring their partners to watch the ultrasound screen.
- A Full Bladder: We will ask you to arrive with a full bladder. This helps tilt your uterus into a straight position and creates a clear “window” for the ultrasound, allowing Dr. Priya to see exactly where she is going.
- The Placement: You will lie back on the exam table, similar to a routine pelvic exam. Dr. Priya will insert a speculum. Using a very thin, incredibly soft, and flexible catheter, she will gently pass the embryo through your cervix and into your uterus.
- The Screen: Guided by the ultrasound, she will place the embryo in the exact optimal spot in your uterine lining. Once she removes the catheter, our embryologist will check it under a microscope to guarantee the embryo was successfully deposited.
- The entire process takes less than 15 minutes.
The Two-Week Wait
After a short rest in our clinic, you can go home. You do not need strict bed rest; in fact, light movement promotes good blood flow to the uterus. We just ask that you avoid heavy lifting or high-impact exercise.
The embryo will attempt to implant into the uterine lining within the next 48 to 72 hours. From there, the hardest part begins: waiting 10 to 14 days for your official blood pregnancy test (beta hCG). We will guide you on exactly which progesterone medications to continue taking to support your lining during this crucial window.
