In vitro fertilization results in embryos that are “grown” in the laboratory for 3-5 days (a blastocyst stage) where they are transferred inside the womb (embryo transfer) for the purpose of implantation of the fetus and thus the achievement of a pregnancy.
In several cases and for a multitude of reasons, embryo transfer cannot or will not be done in the current cycle, and there may be a need for cryopreservation of embryos.
Indications of cryopreservation of embryos:
- Insufficient endometrium (<7 mm)
- Ovarian Hyper-Stimulation Syndrome
- Abundance of embryos
- In women with multiple implantation failures in a “fresh cycle”
- Social cryopreservation
- Cases of cryopreserved embryos for pre-sun / cancer cancer.
And in other cases.
The cryopreservation procedure is completely safe and is done using the Vitrification method, resulting in excellent embryo survival rates after thawing (close to 100%).
Finally, on the basis of existing scientific data, children resulting from cryopreserved embryos do not run the risk of chromosomal abnormalities and other developmental problems in relation to the rest of the population.
