Frozen Embryo Transfer is a tactic that refers to a step in the process of assisted reproduction in which embryos are stored frozen in liquid nitrogen at a temperature of -1960C.Before transfer Embryo are thawed to normal temperature. Subsequently, they are placed into the uterus of a female with the intent to establish a pregnancy. Interestingly, pregnancy rates are increased following FET, and perinatal outcomes are less affected, compared to embryo transfer in the same cycle as ovarian hyperstimulation was performed. The embryo transfer procedure starts by placing a speculum in the vagina to visualize the cervix, which is cleansed with saline solution or culture media. A soft transfer catheter is loaded with the embryos and handed to the clinician after confirmation of the patient’s identity. The catheter is inserted through the cervical canal and advanced into the uterine cavity. After insertion of the catheter, the contents are expelled and the embryos are deposited. Limited evidence supports making trial transfers before performing the procedure with embryos. After expulsion, the duration that the catheter remains inside the uterus has no effect on pregnancy rates. Limited evidence suggests avoiding negative pressure from the catheter after expulsion. After withdrawal, the catheter is handed to the embryologist, who inspects it for retained embryos. Then after some other medical processes are followed and the procedure stands effectively in the formation of zygote.
