Frozen embryo transfer step by step

Obtaining frozen embryos


The timeline of the FET procedure starts with getting embrions. IVF procedure is usually used for this purpose. IVF with frozen embryo transfer  is also provided by our company.

Follicle development monitoring


Fet procedure does not require the surrogate mother to take fertility drugs, estrogen injections or any form of fertility stimulation. It is done as part of a woman's natural cycle. Thus it does not increase risks of side effects like ovarian hyperstimulation syndrome. However embryo implantation may only take place during ovulation, a special phase of the female monthly cycle of surrogate mother. Inasmach as the exact timing of this phase shows great individual variability, it is important not to get attached to any specific calendar. To ensure the most precise determination of the right moment, the center's physician performs a transvaginal ultrasound scan.  

LH surge monitoring


Shortly before ovulation, there is a dramatic increase in luteinizing hormone levels. Therefore, physicians add a luteinizing hormone level analysis for the highest accuracy as ovulation approaches.

Documenting Ovulation


Sometimes after an LH surge, the follicle containing the egg does not open and ovulation does not occur. In this case, special medications like methylprednisolone and doxycycline can be used to stimulate ovulation in this case.  

Embryo transfer


According to our clinic's statistics, the success rate of an embryo  freezing thawing procedure is 60-70%. Usually 1-2 embryos are transferred, which reduces the risk of multiple pregnancies. The implantation procedure itself is similar to IVF. A thin catheter is gently inserted into the uterus and the embryos are transferred with a small amount of fluid. The whole procedure is monitored by ultrasound, which increases the reliability of the procedure.

Pregnancy Test


After 14 days, the pregnancy test confirms the success of the procedure and on the 21st day, the heartbeat can be detected by ultrasound check.

Create U Future takes care of the pregnancy all the way to delivery.
