Fertilized eggs are referred to as "embryos," and embryos can be transferred at any stage up to the multicellular blastocyst stage. The most commonly preferred transfer method is the 5th-day transfer, aiming for embryos to be more mature and healthy. Nowadays, frozen embryo transfers are also frequently carried out. This method is an effective option used to enhance the success of treatment and allows embryos to be stored for a more suitable time.

However, one point to be aware of during embryo transfer is the transfer of multiple embryos. When two or more embryos are transferred, the risk of multiple pregnancies increases, and this can lead to unwanted complications after treatment. Therefore, single embryo transfer is a more commonly preferred practice today.

The transfer procedure is performed in an operating room under ultrasound guidance. It is not a painful procedure for patients and generally does not require anesthesia. After the procedure, the patient is given some medications to support the placement of the embryo into the uterus. These medications are used to strengthen the endometrium (the tissue lining the inside of the uterus) and facilitate the embryo's attachment. This treatment, called luteal phase support, continues until the 8-10th week of pregnancy and helps the embryo firmly attach to the uterus.

In vitro fertilization (IVF) treatment is a meticulous process that involves multiple stages, requiring patience and collaboration from couples. The guidance and support of the expert medical team throughout the treatment process increase the confidence of couples in the treatment and have a significant impact on enhancing the chances of success. In IVF, where each step is carefully and meticulously managed, the hope of having a healthy baby always remains alive.
