Involves freezing good quality embryos, which can be used in assisted reproduction treatments in the future.
The origin of these embryos can be:
- Remaining embryos of prior assisted reproduction treatment. These embryos are used to another attempt if pregnancy fails, or future attempts in case the couple wants to expand the family.
- Embryos specifically grown for storage and future use, especially when the couple want to preserve their fertility.
These embryos are kept in liquid nitrogen indefinitely, making it possible to search for a pregnancy with less effort and cost..
