Introduction
In medical terms, FET usually refers to frozen-thawed embryo transfer. Frozen-thawed embryo transfer is part of the in vitro fertilization (IVF) procedure and is typically performed three months after a failed fresh embryo transfer. The success rate of frozen-thawed embryo transfer is associated with various factors, including the recipient woman's basic characteristics, endometrial thickness, and embryo quality grade.
In medicine, FET generally refers to frozen-thawed embryo transfer. The specific analysis is as follows:
Frozen-thawed embryo transfer is a procedure in which cryopreserved embryos are thawed and then transferred. Typically, after ovarian stimulation in women, 1–2 fresh embryos may be selected for initial transfer, while the remaining embryos are cryopreserved for later use. Frozen-thawed embryo transfer is part of the in vitro fertilization (IVF) process. It is usually performed three months after a failed fresh embryo transfer. The procedure involves preparing the woman's endometrium to bring the uterus into an artificial or natural cycle, following which the thawed embryo is placed into the uterine cavity via a transfer catheter, provided that embryos have already been formed. The success rate of frozen-thawed embryo transfer generally ranges between 40% and 60%. The exact probability of success depends on multiple factors, including the recipient woman's baseline characteristics, endometrial thickness, and embryo quality.
It is recommended that individuals considering IVF consult a reputable hospital and, under medical guidance, choose the most appropriate treatment approach.
