Cryopreservation of embryos is a process in which embryos are frozen and stored at ultra-low temperatures for future use in assisted reproductive technology (ART). This technique is commonly used during in vitro fertilization (IVF) when more embryos are created than can be immediately implanted. After fertilization, the embryos are typically cultured for a few days until they reach the blastocyst stage, at which point they are frozen using either slow-freezing or vitrification, a rapid freezing method that prevents ice crystal formation and preserves the integrity of the embryos. Cryopreserved embryos can be thawed and transferred to the uterus in a future IVF cycle, offering flexibility and additional chances for pregnancy without the need for repeated ovarian stimulation and egg retrieval procedures. Cryopreservation of embryos is often used by individuals or couples who wish to delay pregnancy for personal, medical, or financial reasons, as well as by those undergoing medical treatments, such as chemotherapy, that could affect fertility. It is also used in fertility preservation for individuals facing age-related fertility decline or for those participating in egg donation or surrogacy programs. While cryopreservation of embryos is generally safe and effective, with high survival rates upon thawing, potential complications include damage to the embryos during the freezing or thawing process, which could reduce their viability. Additionally, there is a small risk of loss or misidentification during storage. Legal and ethical considerations also arise regarding the long-term storage of embryos, including decisions about the disposition of unused embryos. Despite these challenges, embryo cryopreservation remains a vital tool in fertility treatments, significantly enhancing the flexibility and success rates of IVF.
