En Azul Fertility Experts, we continue to fulfill the dream of many women and couples of having a healthy baby at home, thanks to cutting-edge technology and high quality standards. Vitrification: Thanks to vitrification, today it is possible to conserve oocytes (own and from donors) and embryos without a time limit, keeping their characteristics unchanged. In this vitrification method, the drop in temperature is extremely rapid and prevents the formation of ice crystals that can break the cell membrane. In this way, a better preservation of the internal structures of the cells is achieved. The oocytes and embryos are loaded into special devices and immersed in liquid nitrogen at a temperature of -196 C for very short periods of time. These devices are stored in individual supports duly identified for each patient and are kept in liquid nitrogen tanks at the same temperature. Cryopreserved eggs can be thawed and fertilized in the laboratory and once the embryos are formed, they are transferred to the uterus for implantation. In turn, the vitrified embryos can be thawed and transferred to the patient when she wants to try a new pregnancy, without having to go through the entire process of ovarian stimulation and fertilization again. Today the success rate of vitrified embryos is exactly the same as that of fresh embryos.
