A frozen embryo transfer (FET) cycle is a process that uses embryos that have been frozen During the FET cycle, the embryos are thawed and placed into the uterus. This is done at a time in your menstrual cycle that best supports a pregnancy. Frozen Embryo Transfer (FET) is a type of Fertility Enhancement Technology (FET) that involves thawing and transferring previously frozen embryos into the uterus of a woman who is trying to conceive. The embryos are typically frozen after being created through in vitro fertilization (IVF), allowing for their storage until they are needed. FET can be a useful option for individuals or couples who have undergone IVF but did not use all of the embryos created during the process. By freezing and storing the excess embryos, they can be thawed and used in a future attempt at pregnancy, often with a higher success rate than a fresh embryo transfer. The process of FET typically involves taking medications to prepare the uterus for implantation and then transferring the thawed embryos into the uterus at the optimal time. The success rates of FET can vary depending on factors such as the age of the woman, the quality of the embryos, and any underlying fertility issues.
