Frozen Embryo Transfer

Frozen Embryo Transfer Proccess

When using frozen embryos for conception, the embryos are inserted into the woman’s womb using a delicate tube and are released with a syringe. The process is monitored via an abdominal ultrasound to ensure proper implantation.

After the process is complete, the syringe used for the transfer is examined in the lab to ensure that all embryos were inserted into the womb.

Normally, the patient is advised to rest for an hour or two after the procedure. About 11 days after embryo transfer, blood tests are conducted to check for the presence of the HCG hormone, indicating that successful implantation has occurred and pregnancy has begun. Other tests will be conducted (blood, ultrasound, etc.) to ensure that the pregnancy is progressing normally.

If pregnancy is achieved, the patient must take medicines crucial for the proper development of the embryo for seven weeks after its transfer. There are several options for transferring embryos.

Transfer using the woman’s natural cycle

The physician monitors the development of the follicles up to the ovulation event, and the embryos are transferred for implantation. This process is as natural as possible and does not require the patient to undergo any special hormonal treatments. This method is suitable only for cases in which the patient has regular cycles and normal ovulation.

Transfer using an artificial hormonal cycle

In this case, the patient receives hormonal treatment, which includes estrogen tablets and progesterone capsules inserted into the vagina, and testing of the endometrium. If conditions are ideal and the endometrium achieves the desired thickness, the frozen embryos are inserted.

Transfer using ovulation medication



This procedure is carried out in parallel with attempts to conceive naturally via sexual intercourse. Medications such as Pergonal are used to stimulate the natural ovulation process in the woman’s body. This method is suitable mainly for situations in which the inability to conceive cannot be explained, and there is a high chance of conceiving independently. These medications help prepare the endometrium and enable the implantation of the embryos.
