We will let you know at the time of your embryo transfer whether your remaining embryos are of a sufficiently high quality for cryopreservation. Embryo cryopreservation and storage is done on site.
The implantation rate of the surviving embryos is similar to the "fresh" embryos.
The complexity and the cost of frozen embryo transfer are greatly reduced compared with repeating the full IVF, surrogacy or egg donation treatments.
The main emphasis of the process of frozen embryo transfer is on the preparation of endometrial lining and its synchronization to receive and support the frozen-thawed embryos.
If you conceived during the initial IVF or egg donation treatment and then you achieve a frozen embryo transfer pregnancy, you will have a set of twins (triplets) born months or years apart!
The transfer of cryopreserved/thawed embryos consists of:
- Preparation of endometrial lining
- Thawing and culture of cryopreserved embryos
- Transfer of the surviving embryos into the uterus
- Establishment of pregnancy
There is no increase in birth defects among frozen-thawed embryo pregnancies compared with spontaneous conception pregnancies.
