IVF treatment, where a cryopreserved embryo created in a full IVF cycle is thawed and transferred to a woman’s uterus
Transfer of frozen embryos is a part of the assisted reproductive technique, which involves thawing and transfer of frozen embryo/embryos obtained as a result of the complete in-vitro fertilization cycle in the uterine cavity.
Growth of the embryo/embryos obtained during in-vitro fertilization, and, if necessary, freezing occurs on the 2nd -3rd or 5th -6th day of their development. 5-6 day old embryos are called blastocysts.
Preparation of the endometrium in the uterus for the transfer of the frozen embryo/embryos takes about 2-4 weeks. The frequency of pregnancy is equal in both frozen and fresh IVF cycles. Pregnancy is confirmed in 10-12 days after embryo transfer.
