It will be the last stop in the journey towards building your family. While this will look similar across the board, we take great pride in our diligence, security, and carefulness when it comes to any point in the IVF process, especially the embryo transfer. Often times, your doctor will make a suggestion which is best for your protocol.
Instead, it will be monitored and grown in the lab for approximately 5 days. If all levels appear optimal, the fresh transfer will happen at that point. The frozen embryo was also monitored and grown in the lab for days to make sure of its viability, then it was carefully stowed away for cryopreservation until your eventual embryo transfer.
The timing of the ET can differ and will depend on if you are proceeding with a fresh or frozen embryo transfer. The ET process usually takes place five days after egg retrieval.
During that waiting period, the eggs are mixed with sperm so fertilization can take place. By day five, the embryo s are now considered a blastocyte, consistency of cells, and are ready for transfer. Your pregnancy test is approximately 9 long days after Transfer. Your embryos were most likely frozen five, six, or in some cases, seven days after egg retrieval.
In cases like this, the process can take weeks from the time you get your menses. Once cleared to start a cycle, you will take an oral medication called Estrace for approximately weeks. This helps to thicken and optimize the lining of your uterus for implantation. You will then be instructed to begin intramuscular progesterone injections ouch! Your Transfer will take place 6 days after starting progesterone.
The timing is critical to the success of your Transfer. Similar to a fresh embryo transfer, your pregnancy test will take place about 9 days after transfer. Both partners must sign. When you decide to begin a frozen cycle, please contact our office and let us know. We will then review your records to ensure your pre-screening is up to date. If necessary, we will order any repeat screening tests. If appreciable time has passed since you last consulted with your physician, we will schedule a follow-up visit with your physician.
A FET cycle will take approximately 6 to 8 weeks. A cycle typically begins with 3 to 4 weeks of daily birth control pills to suppress the normal ovarian cycle, as it would lead to ovulation. After the course of birth control, you will need a baseline assessment involving bloodwork and ultrasound. Depending on the test results, your physician may instruct you to begin sequential injections of estrogen to build the uterine lining.
After a designated period of time on the estrogen injections, you will return for bloodwork and a transvaginal ultrasound lining check. If the lining check demonstrates that your hormone levels are appropriate and your endometrial lining has thickened, your physician will likely instruct you to add daily injections or vaginal suppositories of progesterone to your medication regimen.
Your nurse will then confirm an FET date and you will come in for your transfer several days later. Estrogen and progesterone continue after the transfer, and through the blood pregnancy test about 2 weeks later. Success rates for frozen embryo transfer cycles vary considerably by the program handling the case. Embryo implantation after frozen blastocyst transfers FET can be slightly delayed compared to that seen with fresh blastocyst transfer. However, the embryo implantation process is not different enough to warrant changing the timing of the blood pregnancy test.
Frozen blastocyst transfers should have hatching and the beginning of implantation by about days after the FET. Early pregnancy detection following blastocyst transfer is possible with a sensitive blood assay for HCG hormone by about 9 days after a fresh or frozen blastocyst transfer.
A urine HPT home pregnancy test can be done by 10 to 12 days after blastocyst transfer fresh or frozen , if it is a sensitive, high quality test kit. We are here to answer any questions or concerns you may have so that you feel completely confident when taking the first step toward building your family.
