Cryopreservation cycle
It is an IVF cycle that uses frozen biological material – embryos. If necessary, the cryopreservation cycle makes subsequent assisted insemination attempts cheaper, faster and more convenient. It has been proven that cryopreservation does not affect the future child’s health in any way.
What is a cryopreservation cycle?
An IVF procedure allows inseminating not just one or two egg, but close to ten. Two or three embryos are planted into the uterine cavity in a single IVF cycle, while the remaining ones can be frozen so that the attempt can be repeated in case of failure (or after some time for another pregnancy). The cryopreservation cycle ends with the transfer of unfrozen embryos into the uterine cavity.
What are the advantages and downsides of the cryopreservation cycle?
A cryopreservation cycle is cheaper than a full IVF cycle, but its success rate is lower – 30%. The cryopreservation cycle eliminates extra hormonal stress, as it does not require additional stimulation of follicles.
How long can frozen embryos be stored? How safe is this method?
Frozen embryos can be stored for decades. They are stored in liquid nitrogen in special containers at minus 196 degrees Celsius. ISIDA clinic has extensive experience storing frozen genetic material. In our practice, a woman gave birth to a healthy child after unfreezing an embryo cryopreserved for seven years.
