A fetus can be frozen as a blastocyst, typically around 5 to 6 days after fertilization, when it has developed sufficiently for cryopreservation. This process is commonly used in assisted reproductive technologies, such as in vitro fertilization (IVF). The freezing is done using specialized techniques to ensure the embryo's viability upon thawing. It's important to note that the term "fetus" generally refers to a later stage of development, while embryos are the correct term for the early stages before fetal development begins.
