Transfer Of Embryos Into The Uterine Cavity

The final fourth stage of a successful IVF protocol is transferring the embryo to the mother’s uterus (biological or surrogate). This process is also called a boost transfer. In CLINIC, embryo transfer into the uterine cavity is mainly performed on the 5th-6th day (the developmental stage of the “blastocyst” embryo), which is the most influential modern method based on severe and extensive world research in this field In vitro fertilization. According to indications, in rare cases, embryo/embryo transfer can be performed on the third day after puncture and fertilization. This is the end of the phase where reproductive and embryologists intervene during conception. The embryo develops naturally after being transferred to the uterine cavity. What is included in IVF stage 4? The embryo transfer stage includes:

• Select one or more embryos to transfer to the uterine cavity.
• Prepare the woman for the pick-up procedure and determine the date she will go to the clinic.
• Personalized Embryo Transfer.

After the operation, women do not need to maintain a supine position for a long time and do not need to monitor and stay under a doctor’s supervision. Therefore, she usually leaves the clinic within an hour of talking with a fertility specialist. Preparing a woman for embryo transfer If natural (unfrozen) embryos are used for replantation in the current IVF cycle, the woman does not need special preparation. After puncturing and collecting mature eggs (oocytes), she is advised to: Avoid hypothermia, and avoid contact with people who have signs of respiratory infection, fever, or recent travel. Do not take any other medicines or herbs without consulting a doctor. After all, some of them have potential teratogenic effects (they can cause fetal malformations), affect the uterus’ tone and hormone levels, and change the state of the blood clotting system. Continue to maintain a healthy lifestyle and limit exposure to unfavorable physical and chemical factors. The purpose of all these recommendations is to maintain the most favorable embryo implantation conditions after reimplantation, reduce the risk of abnormal development, and prevent spontaneous abortion of pregnancy. Preparing embryos for transfer The preparation phase includes the mandatory selection of embryos to be transferred. In this case, embryologists will focus on many signs:

• The usefulness of the external morphology of the embryo;
• The correctness of the structure formation in all cells of the blastocyst;
• Sufficient speed and unity of their previous division.
• If indicated, a preimplantation genetic diagnosis can also be used.

The embryos used for replantation are expected to have the highest possible quality. After all, this significantly increases the likelihood of implantation, which is the beginning of pregnancy. However, embryos of medium or even low quality are usually transferred. How embryo transfer is performed Embryo transfer does not require the woman to be hospitalized, and it takes no more than 10 minutes. This procedure does not cause any obvious discomfort to the patient, so that the procedure can be performed even without local anesthesia. This includes: When the woman is in the gynecological chair’s lying position, the vaginal speculum is introduced into the cervix. A special catheter with a diameter of no more than 2 mm is precisely guided, and the non-invasive tip is passed through the cervical canal.
