According to world statistics, programs that use cryopreservation of embryos are at least as effective as programs that use fresh embryo transfer. What is the reason for this? Firstly, when using an FET program, the endometrium is better prepared, which means that the chance of attachment of the embryo is higher. Secondly, many reproductive health clinics use only high-quality cryopreservation techniques.

What Is Embryo Transfer?

The frozen embryo transfer procedure is embryo transfer into the uterine cavity. It’s painless for a patient, and it doesn’t need anesthesia while taking only 10 minutes. A female patient rests for 30 minutes after the embryo transfer, and then she can return home, yet any stresses must be avoided.

Implantation Timeline

As a rule, a doctor transfers embryos within 2-3 days of the moment of taking the eggs. Couples with repeatedly failed transplants are advised to implant the embryo 5 days after the puncture (blastocyst stage). Thus, the maximum organicity of natural cycles is observed. For frozen embryo transfer, the doctor uses the best embryo that has the maximum chance for a successful pregnancy.

What is a Cryoprotocol?

It stands for several procedures when embryos are frozen and then transferred to the uterine cavity. The difference between IVF and the cryoprotocol is that the eggs to be fertilized are frozen for a while, followed by embryo transfer.

A frozen embryo transfer cycle is used for the second phase. It’s the second menstrual cycle of a woman (during the first cycle, preparations and deriving of eggs take place). It’s very important to adhere to the calendar for frozen embryo transfer, which is monitored by doctors. As a rule, embryo transfer is performed in 4 weeks, although longer periods are possible, depending on the specific situation and the needs of the patient or couple.

The second phase of the cryoprotocol, also called the frozen embryo transfer protocol, is used even in the cases when the sexual function is dying out in the female body.

The thawing of embryos occurs according to a special temperature scheme. Such an approach preserves the viability of the embryo.
