Cryopreservation is the process of freezing biological material for its long-term storage with the possibility of subsequent defrosting and restoration of all biological functions. At the Nurai Clinic, we offer cryopreservation services for eggs, sperm and embryos. Cryopreservation is most effective at a young age, when the sex cells have not yet undergone age-related changes. If you have questions or are considering cryopreservation, the specialists at the Nurai Clinic are ready to provide detailed advice and support at all stages of the process.
