Frozen embryo transfer (FET) is a procedure in which a previously frozen embryo is thawed and transferred to the uterus of a woman who is trying to become pregnant. This procedure is typically used in in vitro fertilization (IVF) treatments, in which eggs are harvested from a woman, fertilized with sperm in a laboratory, and then either transferred to the uterus as fresh embryos or frozen for later use.
The frozen embryos are stored in a cryopreservation tank at very low temperatures in order to preserve the integrity of the cells. When the woman is ready for pregnancy, the embryos are thawed and then transferred to the uterus. This procedure allows for better timing of the transfer and improved pregnancy outcomes.
FET can also be used in cases of genetic testing, where the embryos are tested before being thawed and transferred, or in cases where the woman had a miscarriage or failed fresh IVF cycle.
The procedure for frozen embryo transfer (FET) typically involves the following steps:
It’s important to note that the timing of the transfer is crucial, and the best time to transfer the embryos is determined by the woman’s menstrual cycle and the development of the embryo.
Fresh embryo transfer (FET) is a procedure in which a recently created embryo is transferred to the uterus of a woman who is trying to become pregnant. This procedure is typically used in in vitro fertilization (IVF) treatments, in which eggs are harvested from a woman, fertilized with sperm in a laboratory, and then either transferred to the uterus as fresh embryos or frozen for later use.
During a fresh IVF cycle, fertilized eggs (embryos) are allowed to grow in the laboratory for a few days before being transferred to the uterus. The timing of the transfer is crucial, and the best time to transfer the embryos is determined by the woman’s menstrual cycle and the development of the embryo.
The fresh embryo transfer is performed by a thin, flexible catheter passed through the cervix into the uterus, the procedure is usually done under sedation or local anesthesia and is relatively quick and painless.
