Embryo transfer

Cryo-embryo-transfer (FET)

• The term FET, which stands for frozen embryo transfer or cryoembryotransfer, is usually used for the transfer of a previously frozen embryo.
• The essence of cryoembryotransfer is to prepare the endometrium, that is, to perform the transfer when the chances of embryo implantation are highest.

It is done in women who have regular periods.
• The patient comes to the office when she gets her period and an ultrasound examination is scheduled. In
• Depending on the size of the dominant follicle, the day when blood sampling for LH analysis begins is determined.
• Most often, LH is analyzed for 3-4 days to determine the day of ovulation and then on the second, third or fifth day after ovulation, embryo transfer is performed, depending on the day the embryo was frozen. After the transfer, progesterone is most often used.

Embryo transfer

Embryo transfer is a key step in in vitro fertilization, where embryos are transferred into the uterus to achieve pregnancy.

Embryo transfer by day

Embryo transfer is done on the second, third or fifth day after aspiration.

Depending on how many embryos there are, how they are developing, previous procedures, and discussions with the couple, it is decided on which day the embryo will be returned to the uterus.

An embryologist talks to a patient.

Most often, a single embryo transfer is performed, while in certain situations two embryos are returned.

 

  • The patient arrives for the embryo transfer with a full bladder about 30 minutes before the planned transfer time and is placed in the patient room.

Embryo transfer

  • After that, the patient goes to the operating room where the transfer is performed. The transfer is performed on the gynecological table.
  • Anesthesia is not required for embryo transfer.
  • A speculum is placed in the vagina, which allows visualization of the cervix.
  • The assistant holds the ultrasound probe on the stomach.
  • The gynecologist places a thin external catheter into the cervix.
  • When the tip of the catheter is visible on the ultrasound screen, the embryologist brings in the internal catheter with the embryo.
  • An internal catheter is then placed into the uterine cavity.
  • When the tip of the catheter is identified in the middle of the uterine cavity, the embryo/embryos are “inserted” into the uterine cavity.
  • After the embryo transfer is complete, a “white dot” of about 1-2 mm is visible on the screen, which is actually the fluid and air surrounding the embryo. The embryo is 0.1-0.2 mm in size and cannot be seen on the screen.
