Frozen Embryo Transfer

FET

There are situations in which, after an in vitro fertilization procedure (IVF) and ovarian puncture, many eggs are obtained, and after fertilization, more embryos are left than necessary for transfer in a certain cycle, or for various reasons, embryo transfer is impossible in this cycle. Then, at the request of a couple, embryos can be saved by resorting to cryopreservation (in our clinic, vitrification is used – the method of rapid freezing). Frozen material may be used if necessary later. When the couple is ready to conceive again, the embryos are thawed and can be used to retry if the IVF procedure is negative and / or for the birth of the second and subsequent children in the future. When the couple decides to try again, the embryos are thawed and transferred into the uterine cavity using a thin catheter and under ultrasound control. This procedure is completely painless and occurs without the use of anesthesia. Sometimes, before the embryo is transferred to the uterine cavity, the preparation of the endometrium (uterine mucosa) with hormonal preparations and always is necessary. Also during the transfer of embryos, ultrasound control is necessary, but, unlike the fresh IVF cycle, repeated stimulation and ovarian puncture is not needed.

After embryo transfer into the uterus, there is no need to observe any particular regimen. After manipulation, the patient can go home, to work and do all the usual things. Odanako, it is worth remembering that after embryotransfer women are not recommended physical and emotional stress.
