Cryopreservation is a group of processes of preparation, freezing and storage of human gametes, preimplantation embryos and tissues at ultra-low temperatures, most often in liquid nitrogen. It plays an important role in assisted reproduction, as it allows reproductive cells collected and / or fertilized in one treatment cycle to be used for fertilization and / or implantation in the patient’s uterus in a future treatment cycle. This increases the effectiveness of infertility treatment and reduces costs and discomfort for patients.
In 2008 SBALAGRM “Sofia” includes vitrification as the main method for freezing gametes and embryos. This is an ultra-fast freezing technique that results in the formation of a glassy state in the living cells. This method has been known to avoid the formation of ice crystals in the structure of reproductive cells and embryos during freezing and thawing. By thawing sperm, eggs and embryos frozen by vitrification, we achieve over 90% cell survival.
