Embryo transfer can be done on the second or third day, or on the fifth or sixth day (blastocyst stage). Embryos are transferred to the uterus with a thin tool called a transfer catheter produced for this procedure. Embryo transfer is a very simple and painless procedure for the expectant mother. After the embryos are placed in the catheter and the cervix is ​​cleaned, they are usually placed into the uterus vaginally with an ultrasound scan performed from the abdomen. The number of embryos to be transferred is determined according to the expectant mother’s age and the quality of the embryos obtained. After the embryo transfer, the expectant mother can return home after a 1-hour rest. The person can return to their daily life and start working the day after the transfer. Progesterone hormone is used to support the pregnancy expected to occur after the embryo transfer. The patient is called back to the clinic for a pregnancy test 12 days after the embryo transfer. A pregnancy test (beta hCG) is performed here. The result of this test is used to determine whether there is a pregnancy. Those with a positive pregnancy test are called back 2 days later to have a test done again. In a healthy pregnancy, the beta hCG value is expected to increase approximately 2-fold after two days.
