How is Embryo Transfer Done?

We perform embryo transfer on the 5th day, that is, at the blastocyst stage, in patients whose embryos of appropriate quality and number are selected according to the existing embryo quality 2 days after the oocyte pickup day, and on the 3rd day, that is, in the cleavage stage, in patients who have a small number of embryos and therefore do not have a choice.

With embryos in the blastocyst stage, that is, transferring 5 days after oocyte pickup, the chance of pregnancy becomes higher compared to the 3rd day transfer. Because some embryos cannot continue their development from 3 to 5 days and they are naturally eliminated. Thus, the embryo with a high chance of attachment to the uterus can be selected with higher accuracy. Of course, the embryos can be followed up to the 5th day in the laboratory become available only in the presence of appropriate laboratory conditions. You can find detailed information on this subject in my article “Microinjection and Embryo Follow-up”.

In our clinic, we transfer on the 5th day in 70-75% of our patients that have fresh transferred embryo.

In patients with good quality embryos, apart from those transferred, embryos of appropriate quality can be frozen and stored using the vitrification technique on the 5th or 6th day. After freeze-thaw treatment, survival rates are 99-100% and pregnancy rates can be achieved at least close to fresh embryo transfer. You can find detailed information on this subject in my article called “Embryo Freezing”

Embryo transfer is done during a state of congested urine. Because when the bladder is full, the inclination of the uterus is corrected and thus, it is possible to see clearly from the abdomen with ultrasonography, and the embryo can be transferred much more easily.

An examination instrument called speculum is placed in the vagina before the transfer of the embryo, and then the cervix is cleaned with sterile liquid. Afterwards, the map of the entry route into the uterus is drawn with an empty trial catheter, and then the embryo-loaded transfer catheter is passed through the cervix and the embryos are transferred into the uterus. During the procedure, the uterus is observed by ultrasonography from the abdomen and the place where the embryos will be placed is clearly seen and decided.

During the embryo transfer process, no pain is felt. We transfer our patient to her room on a stretcher, so she can leave from our clinic after resting for 30-45 minutes. It is possible to go to the toilet 10-15 minutes after the transfer or urinate on disposable sliders in bed.

After transfer of the embryo, some supportive drugs that enhance the attachment of the embryo to the uterus should be used, and these drugs may vary according to the drug protocol we apply to the couple. Our nurses will tell you which drugs and for how long you should use these drugs.
