With modern methods, the probability of pregnancy after frozen embryo transfer is just as high as with fresh embryo transfer.
The key to a successful outcome is careful planning: the transfer is timed so that the uterus is as receptive as possible for embryo implantation. We always select the most suitable treatment method on an individual basis, taking your overall situation into account.
Frozen embryos can be transferred either during the woman’s natural cycle or during a cycle prepared with hormone therapy. Over 97% of embryos survive thawing well, and the success rate of the FET procedure averages 30–40%.
Frozen embryo transfer is particularly suitable for those who produce more than one high-quality embryo during IVF treatment. If pregnancy does not occur after a fresh transfer, these embryos can be used in the next artificial insemination procedure (FET) without undergoing new ovarian stimulation.
This makes the treatment easier and less taxing.
In summary, embryo freezing provides greater flexibility in scheduling treatment and increases the likelihood that a single treatment cycle can result in multiple opportunities for pregnancy.
Vitrification is a rapid and gentle method that prevents the formation of ice crystals and protects the embryo’s structure. Frozen embryos are stored in liquid nitrogen at –196 °C under strictly controlled conditions to ensure their safe preservation for future FET procedures.
The same method is also used to freeze eggs and sperm.
The transfer of a frozen embryo can be timed in several ways:
In a regular cycle, ovulation occurs approximately two weeks before the start of menstruation. With an irregular cycle, timing can be more challenging, and using an ovulation test can be helpful.
The precise determination of ovulation is essential for timing both insemination and embryo transfer. Our experienced fertility specialists will help you choose the most suitable method for your situation and develop an individualized treatment plan.
The results are often comparable to or even better than those of fresh transfers, especially when embryo quality and endometrial receptivity are good.
Embryo freezing provides flexibility in timing your fertility treatment and allows you to continue the process at your own pace. Embryos maintain their quality for years, making it possible to plan for future children without the need for a new stimulation cycle or egg retrieval. A single treatment cycle can provide multiple opportunities for pregnancy, offering a sense of security and peace of mind that you can proceed with your treatment exactly when the time is right.
